Understanding White Box Testing: An In-Depth Guide

Introduction

Software testing is a critical phase in the development lifecycle, ensuring that applications meet quality standards and perform as expected. Among the various testing methodologies available, white box testing stands out for its focus on the internal structure and workings of the software. This comprehensive guide explores what white box testing entails, its techniques, advantages, disadvantages, comparison with black box testing, tools used, best practices, and more.

1. What is White Box Testing?

White box testing, also known as clear box testing, open box testing, or glass box testing, is a method of software testing that evaluates the internal structures, design, and coding of an application. Unlike black box testing, which assesses functionality without knowledge of internal code, white box testing delves into the code itself. This approach requires testers to have access to the application's source code and employs various techniques to validate its correctness and completeness.

1.1 Definition and Terminology

In software testing parlance, white box testing refers to a testing approach that scrutinizes the internal logic and structure of the code. Testers examine how the software processes inputs and executes code paths based on the internal workings, ensuring that all components function as intended.

1.2 Importance of White Box Testing

White box testing is crucial for several reasons. It helps in identifying security vulnerabilities, ensuring code quality by detecting bugs early in the development cycle, and improving overall software functionality. By understanding the inner workings of the application, testers can provide developers with actionable feedback to enhance code robustness and reliability.

2. White Box Testing Techniques

Various techniques are employed in white box testing to ensure thorough evaluation and validation of the software code.

2.1 Statement Coverage

Statement coverage involves executing all executable statements in the source code at least once during testing. This technique ensures that every line of code is tested and contributes to identifying areas of the code that have not been exercised.

2.2 Branch Coverage

Branch coverage aims to test all possible branches or decision points in the code. Test cases are designed to ensure that each decision in the code is evaluated both true and false, thereby validating different logical paths within the application.

2.3 Path Coverage

Path coverage aims to test all possible paths through the code, considering different combinations of decisions and loops. This technique ensures comprehensive testing by verifying that every possible execution path is exercised during testing.

2.4 Loop Testing

Loop testing focuses on validating the loops in the code to ensure they function correctly under various conditions. Test cases are designed to execute loops with different inputs, ensuring that they iterate the correct number of times and terminate appropriately.

3. Advantages of White Box Testing

White box testing offers several advantages that contribute to the development of robust and secure software.

3.1 Improved Code Quality

By examining the internal structure and logic of the code, white box testing helps in identifying and rectifying bugs early in the development process. This proactive approach improves code quality and reduces the likelihood of critical issues surfacing in production.

3.2 Early Detection of Errors

White box testing facilitates early detection of errors by uncovering issues in the codebase before they manifest into significant problems. This early detection allows developers to address and resolve issues promptly, minimizing the impact on project timelines and costs.

3.3 Better Test Coverage

White box testing ensures comprehensive test coverage by scrutinizing the internal workings of the application. Testers can design test cases specifically to target critical components and functionalities, thereby validating the entire codebase thoroughly.

4. Disadvantages of White Box Testing

Despite its advantages, white box testing has certain limitations that need to be considered.

4.1 Requires Deep Knowledge of Code

White box testing demands an in-depth understanding of the codebase, which can be challenging for testers who are not familiar with the application's internal structure. This requirement necessitates skilled resources capable of effectively navigating and evaluating complex code.

4.2 Time-Consuming

Due to its detailed nature, white box testing can be time-consuming, especially for large or complex applications. Testers need to design comprehensive test cases, execute them thoroughly, and analyze results meticulously, extending the overall testing timeline.

4.3 High Cost

The need for specialized skills and the extensive time requirement in white box testing can lead to increased testing costs. Organizations may need to allocate additional resources and budget for training testers and implementing robust testing strategies.

5. White Box Testing vs. Black Box Testing

To understand white box testing better, it is essential to compare it with black box testing, another prevalent testing methodology.

5.1 Key Differences

White box testing and black box testing differ fundamentally in their approach, scope, and focus areas. While white box testing examines the internal structure and logic of the code, black box testing evaluates the software's functionality from an end-user perspective without knowledge of internal code.

5.2 Complementary Approaches

Despite their differences, white box testing and black box testing are complementary testing methods. Organizations often employ both approaches to achieve comprehensive test coverage, combining internal code validation with user-centric functionality testing.

6. Common Tools for White Box Testing

A variety of tools are available to facilitate white box testing, each offering unique features to aid in the testing process.

6.1 JUnit

JUnit is a popular testing framework for Java applications that supports the creation and execution of white box tests. It provides assertions, test fixtures, and test runners to automate and streamline the testing process.

6.2 NUnit

NUnit is a widely-used testing tool for .NET applications, offering robust features for white box testing. It supports parameterized tests, assertions, and setup/teardown methods to validate the internal logic and behavior of .NET code.

6.3 Selenium

Selenium, primarily known for automation testing, can also be utilized for white box testing, especially for web applications. Testers can leverage Selenium WebDriver to interact with web elements, execute JavaScript, and validate the internal functionality of web applications.

7. Best Practices for Effective White Box Testing

Adhering to best practices can significantly enhance the effectiveness and efficiency of white box testing efforts.

7.1 Comprehensive Test Planning

Developing a well-defined test plan is essential to ensure thorough and systematic white box testing. Testers should outline test objectives, identify critical areas of the codebase, and prioritize test cases based on risk and impact.

7.2 Code Reviews and Inspections

Regular code reviews and inspections play a crucial role in white box testing. Collaboration between developers and testers helps identify potential issues early in the development cycle, fostering code quality and reducing the likelihood of defects.

7.3 Continuous Integration

Integrating white box testing into the continuous integration (CI) pipeline promotes early error detection and resolution. Automated testing frameworks can be leveraged to execute white box tests automatically whenever code changes are committed, ensuring code stability and reliability throughout the development process.

Is integration testing White box testing

In the previous month's blog I wrote about integration testing….so now we are very clear about Integration testing….  In this blog, I am having a blog about Integration testing with White box testing…  So let’s learn ‘White Box’ testing….  Basically in  Integration Testing, there are 2 types of Testing :  1. White Box Testing  2. Black box Testing  —-----------------  Let’s  take description note for White box testing:  In White Box testing tester is having deep knowledge of source code, technology and architecture used in system…    So while doing Integration testing with white box methodology..tester test the system with combining source code of 1-2-3 module and try to track occurred error…   

Black Box Testing :   Where as in black box testing tester do not having knowledge about system and he/she test  system as end user….    Conclusion : Yes Integration Testing is White Box Testing.

── try again

a/n. i've been sitting on wanting to create a small scene like this for a while now. so here ya go! lemme tell ya'll... breastfeeding is not always this magical and beautiful thing that people make it out to be. it hurts like hell, my bloody nipples can attest.

cw: domestic fluff. angst with comfort. satoru's trying to make breastfeeding easier for you.

“Satoru,” you whisper, voice tight with frustration. “She won’t latch.”

You’re trying not to cry.

Looking down at your newborn, you can see her frustration—tiny fists clenching, soft, hungry cries spilling from her mouth as she wriggles restlessly in your arms. You shift again, adjusting her position, cradling her closer, trying—begging—for something to click.

But it doesn’t.

Her mouth bobs and searches blindly, cheeks flushing red with effort, and the desperation building in her fragile little body mirrors your own.

“I—I don’t know what I’m doing wrong,” you choke out, blinking hard as tears blur your vision.

You’re exhausted. Beyond it. The sleepless nights at the hospital. Your body aches in places you didn’t even know could hurt. And this—this thing that was supposed to be natural, instinctual, beautiful—feels awkward and impossible—like a test you’re failing over and over again.

“Please, baby girl…” your voice trembles as you guide her to your breast one more time. “Just—c’mon—o-ow!”

She latches, but it’s wrong. A searing pain shoots through your chest and you flinch, instinctively pulling her away. Your nipple throbs—red, sore, screaming for relief. With a shrill cry, your baby’s tiny face crumples in protest, and your own tears finally fall—hot and helpless.

“Why is this so hard?” you whisper, voice cracking as you hold her close, shaking.

“Hey, hey… it’s okay. You’re doing everything right.”

Satoru's voice is low behind you—steady, but laced with worry.

His hands come to rest gently on your shoulders, warm and trembling, his thumbs moving in slow circles like he can massage away the frustration knotting in your muscles.

“She’s only a few days old…” he murmurs, leaning down to kiss the top of your head, lips lingering in your hair. “She’s still learning. Fuck… we are too.” He exhales shakily. “You’re doing the best you can, sweetheart. Please don’t be so hard on yourself.”

He straightens, blue eyes darting around the room like he’s searching for something—anything—to help.

“What can I do? Do you need anything? Where’s that—hang on—where’s that damn pillow thing…?” he mumbles, and you watch through watery eyes as he scrambles, clumsily grabbing the nursing pillow, adjusting it like he’s trying to solve a puzzle without the picture on the box. His movements are uncoordinated, frantic—but full of love.

Satoru kneels beside you as you try again, baby blue eyes flicking between your face and your daughter’s, willing the pieces to fall into place.

"C'mon baby girl... be nice to your momma for me, yeah?"

But when your little one latches again and you gasp, pulling her off with a pained cry, your resolve shatters.

“I—I can’t do it Satoru!” you say, brokenly. “I can't get her to latch, and when she does… it just hurts. So much.”

You feel like a failure. How can you not feed your baby?

As you look up at him through watery lashes, tears clinging to your cheeks, Satoru's expression cracks. He nods quickly, white brows furrowing as his lips press into a tight line, like he’s holding back the helplessness swelling in his chest.

“I know, baby. I know. Just… wait one sec.”

He’s on his feet in an instant, practically tripping over the edge of the rug as he rushes across the room. A moment later, he’s back—dragging a stool with one hand and clutching a spare pillow in the other. Dropping down in front of you, he crouches low, gently lifting your legs and placing them on the makeshift footrest.

“There,” he murmurs, positioning the pillow with care. “Put your feet up. Maybe if you’re more comfortable…”

Satoru fluffs the nursing pillow again with extra care, tucks the baby’s blanket around her tiny frame, then grabs your water bottle from the side table—uncapping it as he gently places it in your hand.

“C’mon momma... gotta stay hydrated.”

His voice is hushed, but purposeful. You sniffle, taking a sip of water, and he's shifting back toward the kitchen, glancing over his shoulder.

“Um… do you want a snack? I think there’s some of those lactation cookies in the kitchen…" his blue eyes flick back to you, and you see the gears turning in his head. "Or... I can make you something? Or—shit—I’ll Postmate something! What do you want? Fuck, I’ll Postmate everything if it’ll help.”

A tired, wet laugh escapes you—half amusement, half relief. “Great..." you wipe the tears from your eyes, smiling softly. "Now you’re spiraling too...”

He huffs out a sheepish breath, dragging a hand down his face as he plops beside you again. “Yeah… yeah, I am definitely spiraling.”

Reaching up, he brushes a damp strand of hair from your face, fingers grazing your temple with featherlight tenderness.

“You’re in pain...” he murmurs, blue eyes shimmering with concern. “And... I feel helpless just standing here. I can’t feed her. I can’t fix this…” he pauses, lips dropping into an exaggerated pout. “My nipples are completely useless, by the way.”

A choked, breathless laugh escapes through your tears, and his entire face softens at the sound, like it’s the only thing that’s mattered all day.

“What?” he grins. “It’s true. I’ve got nothing going on up here. Decorative at best. Yours, on the other hand—” he gestures with a flourish, “—doing heroic work. Damn sexy, too. Just sayin'.”

You roll your eyes through the blur of tears, laughing again, and lean into the warmth of his palm as it cradles your cheek.

It still hurts. You’re still exhausted, still raw, still aching in every possible way.

But in this moment—wrapped in Satoru's love, soothed by his gentle chaos and relentless care—you don’t feel quite so alone.

And somehow, with him by your side, you find the strength to try again.

And again.

And again.

Until finally… you get it right.

Raspberry Girl Previous + masterlist + AO3 Simon Riley/female reader CW: 18+ daddy kink, size kink, forced orgasm.

“Ghost.” 

He looks over the rim of his glasses before sliding them off completely and tossing them onto the stack of papers spread out in front of him. "Gaz." 

“You out of here soon?” Kyle’s in the doorway with his arms crossed, slight smirk twisting his lips. 

“Tryin’ to be.” The administrative side of this job will be the death of him one day, leaving him buried beneath mountains of paperwork. “Guys get their gear done?” He nods. “Shoot test?” 

“All complete. Evals loaded in the portal.” He’s frighteningly efficient, something Simon’s come to rely on.

Kyle has no idea there’s a recommendation for promotion in this stack of nonsense on his desk. 

He’s going to miss him when he makes captain. 

“Good work as always then.” His phone buzzes. Three times. 

>I think I should be another hour, or maybe less. 

>But of course don’t feel like you have to rush over here, I’m fine to wait. I don’t mind. I know I gave you a time estimate this morning so of course I don’t expect you to work around me. 

>I just meant to say I’m ready whenever. That’s all. But no rush, again. 

Kyle sighs with a chuckle. "That your girl?" Simon waves him away.

“Have a good weekend, Lieutenant.” 

“You too, Captain.” 

“Hi.” Something in him settles at the sight of you. Tired, but excited. Half ready for bed, half ready for him, you’re standing in the shop next to one of the little tables, your work bag and jacket slung on a chair. 

“Hi sweetheart.” You’ve shed some layers in the last week, become a little less inhibited with him, a little more confident, slowly adjusting, and he’s proud of you. 

You’ve been good. 

“How was your day?” 

“Oh, fine. I’m tired.” Your eyes go wide with panic. “Not too tired though, not like t-tired I want to go home. Like, to mine uh, I still-” It doesn’t take much to knock you off balance, still exploring this new world, the one he’s building for you, his sweet fresh fawn. 

“It’s alright.” He reaches, cupping your cheek. Physical contact seems to soothe you. He thinks it’s because there’s a live, tangible tether connecting you to the now, to him, instead of whatever is going on in your head. “You were up really early sweetheart, it’s understandable you’re tired.” You were awake before him this morning. Sent your usual wake up text well before the sun rose with a hurried explanation about a last minute catering order and a panicking bride. 

I said I’d do it. I felt bad. 

It wouldn’t be so rough if you hadn’t been at work late the night before for something else. 

It’s clearly wiped you out, and he’ll need to shift gears. “Are you ready to go?” You take a half step back and hold up your pointer finger, inclining your head towards to the back of the bakery. 

“Uh, wait. I forgot something, one sec.” 

You return with a big white box cradled in your hands. 

“What’s in there?” 

“Oh I made you something. Us. I made us something. For after dinner, if you want. Obviously if you don’t want it that’s fine you don’t have to eat it, it might not even be your thing, which is fine, I just-” He steps into your space and you trail off, eyes going to his without prompting. He blocks the world out, closes in, palms the back of your neck.  

“It’s me baby. Just you and me, and there's nothing to worry about. You’ll never make a single thing I won’t like, right?” 

“R-right. I know that.” You’re bobbing in a continuous nod, looking away to study something on his shirt. 

“What is it?” 

“Pie. Boston cream pie.” Cream pie. Blood flows to his cock and he momentarily gets lost in his own head. 

“Tell me.” Fat tears roll down your cheeks, hands following him desperately as he rears back and folds your knees to your chest, staring at where his cock is moving in and out of your body, everything about him too big, nearly too big to fit inside you. “Where do you want daddy to put his cum?” 

“I-inside. I want your cum inside me daddy, pl- oh- please.” His balls tighten as he grinds his hips, licking an errant tear running down your face. His girl. His. In his arms, his bed, crying on his cock. 

“Only good little girls get daddy’s cum, baby. Have you been good?” 

“I’ve been good, I’ve b-been so- ah- f-fuck-” The wand buzzes to life, hovering just over your clit as you shake your head frantically. “No nonono, I can’t anymore, I c-can’t.” 

“Yes you can,” he thrusts deep and you gasp. You’ve already come four times, but he wants more, needs more, wants to wring every single one he can get out of you before he empties his balls inside your pussy. 

When he finally slides it across your swollen little nub, you howl. 

“Oh- no-” you whine, nails digging into his forearms, muscles already bearing down on him, breaths turning into short rasps.  

“I know. Breathe baby,” he glides it back and forth, kisses your cheek, your mouth. “Breathe through it- that’s my girl. You can take it.” You’re oversensitive, battling a war between pleasure and pain, and your legs instinctively try to close, prevent the impending explosion you know is coming. “Keep your knees open.” He gives the head of the wand firmer pressure, and you cry, shaking your head no again. 

“It’s too- too much.” Your feet are on his sides, partially bent in half, and he forces one of your thighs wide, giving him a better view of your puffy, tortured clit. 

“Knees open baby girl. One more and daddy will fill you up nice and deep.” You nod, already so close he can feel it, scorching heat pulsing around him, legs trembling as they go lax. “There you go…” he pets your hip, mouth at your ear, soothing and comforting as it rips through you. It pushes him over the edge and he tosses the wand, pins you. Traps you beneath him. All his. 

“Oh my god,” you slur, still riding the wave of your own orgasm, eyes rolling back in your head. It pushes him over the edge.

“Good girl, good fucking girl, so proud of you, takin’ my cum- fuck-” his own voice is choked off as he floods you, ruts like an animal, instinctively forcing as much of his seed into your belly as he can. 

When it’s over, he drinks in the sight of the milky white cream dripping out of your hole before scooping it up with two fingers and pushing it back inside. You’re limp the whole time, and when he slips the plug in, you barely notice. You’ll be pumped full of him until later, and he’ll take it out to give you more. 

“Daddy?” You mumble, half asleep, and he brushes his lips across yours, tucking you into his chest. 

“Right here, baby. I’m right here.” 

“- it’s not really. I mean, the best part about it is the cream, you know? That’s what makes the cake but the layers have to be moist on their own. You can’t just rely on the…” He swallows your words, licks them out of your mouth, cups your face and presses his thumb into your bottom lip afterwards, edging it across your top teeth. “Oh.” You blink, blindsided, and he runs a hand down the back of your head, strokes the back of your neck. 

“Ready then?” You lean into him, a little dazed, off kilter. 

“Y-yeah.” 

 Your toes scrunch at the threshold of the living room, afraid to cross until he flattens his palm on the small of your back.

“Go get comfortable sweetheart.” Battling nerves with a need for sleep, you were unsettled at dinner, sitting at the table, swallowing over and over again long after your food was chewed. There’s something more at play, something larger weighing on you. You left your plate half empty, fork resting at three oclock, twirl of spaghetti and red sauce waiting, and he should have told you to finish, or take one more bite. 

But it's a slow game right now. A careful one. 

“Alright.” You scamper towards the couch, settling into the far side, toes tucked between the cushions. It’s a balancing act, not too much, too too little, and when he sits down next to you with a giant slice of the cake on a plate, you watching him anxiously. Curiously. 

He forks a piece free, and holds it in front of your mouth. “Open.” You do. Immediately. You trust him to feed you, and it calls to the thirst thrumming in his blood, the power of control. “Good girl.” He waits, patiently, ignores the flex of your throat, the butterfly flutter of your lashes. There’s plenty of time for it all. There will be a lifetime (if he’s alive to live it) with you. "What do you say?" 

“Thank you.” 

“Thank you…” He leads, and you follow. His good fucking girl. 

“Daddy,” your whisper is shy, cautious and brave at the same time. “Thank you daddy.” A kiss finds its place on the corner of your mouth, then the full furl of your lips, and you burn alive, flames flickering in your eyes. He takes a bite himself and groans 

“Christ baby.” 

“Do you like it?” When he nods, you grin. 

“Not everyone likes them because they expect a cream pie and that’s not what they get, it’s a cake with vanilla cream between the layers, see?” You point to the thick custard. “It’s not like coconut cream pie, or a banana cream pie, you know?” Cream pie. If you say cream pie one more time. 

“It’s really good sweetheart. Too good.” He helps himself to another bite, offers you one, and then has a third before finally setting the plate down. Silence hovers in the air and he lets it languish, giving you time, all the space you need to give him the worry, the doubt, the weight that's holding you back. 

“Simon.” He smothers his surprise. It’s not the first time you’ve used his name, but your voice wavers on it. Wide doe eyes stare back at him, and then they find the floor. That won’t do. “I don’t know what to do with…”

“With what sweetheart?”

“You. This. U-us? If that’s… if that’s what-” 

“That’s what it is.” He closes what little gap there was between the two of you and pulls your knotted together fingers free, dwarfing your hand with his. “That’s what this is, baby.” The hope, the happiness, blooms across your cheeks and lasts for all of two seconds before worry overtakes it, and you begin tracing the lines in his palm, head down, focusing on the task, slightly shaking. Giving you a chance to walk away would be the right thing to do. 

But he won’t. 

He can’t. 

He’d never give you up now. 

“I’m not… I’ve never… done something like this, I don’t know how.” 

“That’s okay sweet girl, you don’t have to.” The nervous tracing turns to a light scratch. He lets it continue for a beat before folding your hand between his, stopping the movement. 

“I don’t?” 

“No. I’m here, and I’m going to take care of you, make sure you have everything you need. I’m going to keep you happy and healthy and safe, and you don’t need to worry.” A shaky exhale rattles free from your chest, weight of a thousand questions evaporating into thin air, decisions and deliberations rapidly falling away as you settle into a new reality, a new life. One where you’re cared for, supported, and loved. “All you need to do is listen, okay?” 

“Okay daddy.”

Understanding Black Box Testing: An In-Depth Exploration

In the realm of software development, ensuring that an application functions as intended and meets user expectations is paramount. One of the fundamental techniques employed to achieve this is testing. Among the various testing methodologies, black box testing stands out due to its unique approach and versatility. This article delves into the intricacies of black box testing, exploring its definition, techniques, advantages, disadvantages, and best practices.

What is Black Box Testing?

Black box testing, also known as behavioral testing, is a method of software testing that focuses on evaluating the functionality of an application without peering into its internal structures or workings. The tester is only aware of the inputs and expected outputs and is oblivious to the implementation details, such as code structure, design, and architecture. The primary objective of black box testing is to validate whether the software behaves as expected under various conditions.

Techniques of Black Box Testing

Several techniques are employed in black box testing to ensure comprehensive coverage and thorough validation. Here are some of the most commonly used techniques:

Equivalence Partitioning:

This technique divides the input data into equivalent partitions that are expected to be processed similarly by the software. Test cases are then derived from each partition, reducing the number of test cases while maintaining coverage.

For example, if an input field accepts values from 1 to 100, the partitions could be: valid (1-100), invalid (less than 1), and invalid (greater than 100).

Boundary Value Analysis:

Boundary value analysis focuses on testing the boundaries between partitions. Since errors often occur at the edges of input ranges, this technique is highly effective in uncovering boundary-related defects.

For instance, if the valid input range is 1 to 100, the boundary values to be tested would be 0, 1, 2, 99, 100, and 101.

Decision Table Testing:

Decision table testing involves creating a table of conditions and actions, capturing various input combinations and their corresponding outputs. This technique is useful for testing complex business logic and rules.

Each column in the decision table represents a unique combination of conditions, ensuring that all possible scenarios are tested.

State Transition Testing:

This technique is used when the system under test changes state based on input events. State transition diagrams or tables are created to model the states and transitions, and test cases are derived to validate each transition.

For example, testing a login system might involve verifying transitions from the "logged out" state to the "logged in" state based on correct or incorrect credentials.

Use Case Testing:

Use case testing involves creating test cases based on use cases that describe how users interact with the system. This technique ensures that the software meets user requirements and supports typical user scenarios.

Each use case is analyzed to identify the main success path and alternative paths, which are then translated into test cases.

Advantages of Black Box Testing

Black box testing offers several benefits that make it an indispensable part of the software testing process:

User-Centric:

Since black box testing focuses on the application's functionality and user interactions, it closely aligns with user requirements and expectations.

Unbiased Testing:

Testers are not influenced by the internal implementation, leading to unbiased testing and a higher likelihood of uncovering functional defects.

Effective for Large Systems:

Black box testing scales well for large and complex systems, as it abstracts away the internal complexities and focuses on user-visible behavior.

Early Detection of Defects:

By validating functional requirements, black box testing can uncover defects early in the development cycle, reducing the cost and effort required for fixing issues.

Complementary to White Box Testing:

Black box testing complements white box testing (which focuses on internal code structures) by providing a holistic view of the software's quality.

Disadvantages of Black Box Testing

Despite its advantages, black box testing also has certain limitations:

Limited Coverage:

Black box testing may not cover all possible input scenarios, especially if the input space is vast or the test cases are not comprehensive.

Difficulty in Identifying Non-Functional Issues:

Since black box testing focuses on functionality, it may not effectively identify non-functional issues such as performance, security, and usability.

Blind Spots:

Testers may miss certain defects due to their lack of knowledge about the internal implementation, leading to potential blind spots in testing.

Dependency on Test Cases:

The quality of black box testing heavily depends on the quality and completeness of the test cases. Inadequate test cases can result in incomplete testing.

Best Practices for Black Box Testing

To maximize the effectiveness of black box testing, it is essential to follow best practices:

Comprehensive Test Planning:

Develop a detailed test plan that outlines the scope, objectives, techniques, and test cases for black box testing. Ensure that the plan aligns with user requirements and business goals.

Prioritize Test Cases:

Prioritize test cases based on critical functionality and risk. Focus on testing high-priority features and scenarios that have a significant impact on users.

Use a Combination of Techniques:

Employ a combination of black box testing techniques to achieve comprehensive coverage. Techniques like equivalence partitioning, boundary value analysis, and decision table testing can complement each other.

Automate Where Possible:

Leverage test automation tools to automate repetitive and regression test cases. Automation enhances efficiency, consistency, and coverage in black box testing.

Collaborate with Stakeholders:

Engage stakeholders, including developers, business analysts, and end-users, in the testing process. Their insights can help identify critical test scenarios and improve test case design.

Review and Refine Test Cases:

Continuously review and refine test cases based on feedback, changes in requirements, and defect analysis. Keep the test cases up-to-date to reflect the current state of the application.

Perform Exploratory Testing:

In addition to structured testing, conduct exploratory testing to uncover defects that might not be captured by predefined test cases. Exploratory testing encourages creativity and critical thinking.

Conclusion Black box testing is a powerful technique for validating the functionality of software applications. By focusing on inputs and outputs without delving into the internal implementation, it ensures that the software meets user expectations and business requirements. Employing a variety of black box testing techniques, following best practices, and continuously refining test cases can significantly enhance the effectiveness of black box testing. While it has its limitations, when used in conjunction with other testing methods, black box testing plays a crucial role in delivering high-quality, reliable software.

Havin' his baby

neighbor!joel x f!reader

series masterlist | ao3 | masterlist part 2

summary: "I'm pregnant." His face. His totally normal face that was there seconds ago. It goes blank. White as a ghost. Joel blinks once. "You're what?" "It's yours," you blurt out, panicking. "I haven't been with anyone in awhile, and you were the last person..." The one in which you are pregnant with Joel miller's baby.

authors note: so, apologies in advance. this is a prologue of sorts. there won't be some smut for a while. i wanted there to be a bit of build up at first. i imagine reader is like 30s. but you can make her younger. but i still hope everyone enjoys!! tags: MDNI, pregnancy symptoms, implied age gap, joel is older, reader can be anywhere between 28 and mid 30s. reader is not described in this just that you have breast and long enough hair(eventually), no use of y/n, lots of pregnancy in this one. strangers to lovers vibes, pregnancy test. mention of being a mother, mentions of ultrasounds. tommy is in a few seconds of this. tbh, this can be either game joel or show joel. word count: 3.2k

The morning felt worse than the few before. You had woken up in the middle of the night more than once–not ‘cause you couldn’t sleep, but ‘cause you couldn’t shake that feeling of anxiety in your stomach all night. 

The clock beside your bed says 7:45. Small bits of sunshine slip through your cheap not-so-great curtains. The summer heat in Texas. God. And your shitty lack of air conditioning wasn't helping you feel any better.

You sigh. 

Not because you spent most of the night tossing and turning. But for the first time in a year, you missed work. Not just a day. An entire week. You had to get a substitute to cover most of your days.

Teachin’ life and what not. 

You were sick. Nauseous. Your head was killing you. At first, you chalked it up to some bad leftover chinese you’d had.  But by the second day?

You told yourself it was just from being around kids. Kids carried all kinds of germs. Practically little petri dishes, never washing their hands.

By day four. Most definitely, you were gaslightin’ yourself. Telling yourself it wasn’t anything serious. Until you realized your period never showed. You were never late. Never. Always right on time. 

Instead of staying in bed. You drove all the way to the furthest pharmacy from your house that you could find. You didn’t want to run into a single person you knew. 

Truth was, you’ve never had a pregnancy scare in your entire life. 

Not even when you were a reckless teenager fuckin’ around with Billy Davis behind your parents back.  Or that long term boyfriend you had up until last year, Jesse. 

Never even needed to look at a test. But there is a first time for everything, you suppose. You looked over all the boxes. 

How in the hell were there so many different brands? Different kinds? Some had two pink lines. Some had a blue plus sign. What is the difference between a digital one and a regular one?

You pick up the digital box. Flipping it over. Reading the words slowly. Was there really a need to know six days early when you already were a week late? 

This was all…confusing. You feel it too. How drained you are. Filled with so much anxiety that this is real. You are really standing in the middle of a pharmacy because you might actually be pregnant. 

So, you do the only thing you can think of. You buy six different ones. 

‘Cause there was no way six tests could all lie to you, right? No way one of them could give you a different result. 

The drive home was terrible. 

Maybe it’s the car making you feel sick. The Texas heat since the air conditioning in your car also sucked too. Or maybe it’s just… really all of this.

After an awkward run in with Mrs. Sims on your way into the house and fifteen minutes of standing in the bathroom. Six pregnancy tests are spread out in front of you. 

The first four are the easy ones, the kind with the little lines. Two pink lines on the first two. A large square pink plus sign on the other set. Positive.

The digital ones were next. Ninety-nine point nine percent accurate. The first one you pick up has a smiley face on it. 

Like that’s supposed to make you happy. Instead of making you want to cry on your bathroom floor. 

The second digital one just confirms your fate. 

Pregnant.

Six different tests. Six different ways of telling you that you’re definitely expecting. 

Having a mental breakdown about being pregnant wasn’t exactly on your to-do list today. Not ever. 

There’s no pep talk you can give yourself. Tell yourself that everything is gonna be just fine. You’re not happy. You aren’t exactly devastated. You are just numb. 

The handbook of life never taught you how to react when you’re finding out you’re pregnant. Especially when this wasn’t part of the plan. Any plan. 

The details from that night aren’t really there. You remember the bar. You remember goin’ into his house.

You’d only gone out to that rundown bar a few streets over because of Rebecca, your college friend. Who wouldn’t stop complaining you never went out. Never enjoyed life outside of work. 

Girls’ night, she called it. 

But you’d seen him.  Your neighbor. Joel Miller. 

You barely know him. He lives across the street. Waves back at you when you’re getting the mail. Greets you with that southern drawl. Says, “Mornin’.” Helps with things occasionally.

He’s always working. Has a daughter in college. Not that you ever saw her, or paid much attention to what was across the street.

Joel Miller hadn’t been much of an interest to you. Not until that night.

That night he was sitting by himself on a barstool. At the same bar you were at. 

He’s older. Dark greying hair. Hazel eyes. Spends more time looking ahead than looking at you. Which was a change for once. 

After two hours, it turned out you had a lot more in common than you would’ve thought. Both of you like older music. Spent half the night talkin’ about old records alone. Your friend? She was long gone. You’d practically ditched her to talk to someone else. So, Joel offered you a ride home. 

When you got back to his house. The night faded away. You had a few more drinks. But, so did he.

But you. You kissed him first. Drinkin’ and makin’ terrible choices was a thing that happened to you before. That’s why you never liked to drink. But on his couch, in his living’ room, you made the first move.

From there? It was nothin’ you can remember.

You didn’t talk after that. Not really. You had to leave early for work, and Joel? He was in the shower when you snuck out. Not your proudest moment pickin’ up pieces of your clothes. Heading back home. 

The two of you would occasionally wave. And smile. The same polite nods you’d given each other before. But weeks went by, and now. You’re staring’ at six positive pregnancy tests on the counter wondering where this all went wrong. 

You weren’t on birth control. It’s not like you remember much of what happened that night.

That feeling of needing to throw up already started creeping’ back. You’ve barely kept down crackers and ginger ale wasn’t helping either.

And now, you’re back on your knees. Throwing’ up into the toilet again. 

You’re pregnant with Joel Miller’s baby. Something you never thought would happen in a million years. But here you are. 

It’s been over two weeks since you found out. Three days since you went to the OBGYN. Who confirmed what six home pregnancy tests already told you. 

The first appointment was how you expected it to be. Normal. As normal as it could be. You were alone. Too scared to break the news to Joel yet. 

You discussed your options. Which you had spent way too much time thinking about. Eventually you decided that you were gonna keep it. Even before the appointment. 

The doctor talked to you about what to expect. At almost nine weeks. 

How the nausea might last until twelve weeks. Maybe longer. 

“Every woman is different. Experiences different symptoms,” she said. 

She gave you some suggestions. How you can take something called B6 to help. A few home remedies that you could try. Even a wristband that you could put on a pressure point.

She sends you for a dating scan the next day. To confirm how far along you are. Though, by your blood work she estimates nine weeks. But you already knew. 

You sit in the ultrasound room. The smell of those lemon scented bleach wipes filled the room. It was cold. Freezing. And the sweet ultrasound tech shows you your baby. A tiny little bean lighting up the black-and-white screen. You cry. Not because you’re upset…but because it’s real. All of it. A small part of it might be due to hormones. 

They send you home with a photo. That flimsy photo paper. One small, tiny photo of your baby. Yours and Joel’s baby. 

You’re back to work. Back to a room full of kids. Pretending that you’re okay. Pretending that Brenda’s lunch doesn’t make you a little sick. Or that really nasty coffee they kept in the teachers lounge. How was it possible that an off-brand made you nauseous? But the name brand didn’t? When you get home, you look across the street. His brown house. The porch lights off. His truck ain’t there. It rarely is. Maybe it was on the off chance he decided to take a day off. 

You take out your phone. Pulling up his contact. Just Joel. The only text you’ve ever sent him is still sitting there. Not like you deleted your text messages.

It’s from over a year ago. Something about the school needing’ to hire a contractor. 

You: Hey.  You: Are you home?

You knew he wasn’t. 

But you needed an excuse to talk to him. After all…you needed to tell him. This was his baby too. 

Joel: Workin’ late tonight. You need somethin?

You leave him on read. But the truth was. You can’t avoid it forever. 

Saturday morning, while you ate your breakfast. You decide it’s finally time. You leave early enough. Head to the construction site he mentioned he was workin’ at. It was a longer project. Said it would be weeks worth of work. 

This wasn’t exactly the kind of thing you break over a text message. 

Hey Joel, so I’m pregnant. 

That ain’t the best way to deal with this. You drive thirty minutes out there. When you stop the car, it hits you. God, it hits you hard. Harder than you thought it would. You almost talk yourself out of it. Out of this whole ridiculous plan while sitting in your car. 

You shouldn’t do this. Can’t do this. What if he’s angry? What if he’s upset? What if you start crying ‘cause all these damn hormones racing through you? 

You’ve never seen him angry. Never really been around him enough to know. He’s always been just… himself. Brooding. Seems lonely at times. Keeps to himself. But he’s always just…Joel. 

The courage finally comes. You get out and walk toward the trailer. But Tommy, Joel’s younger brother, stops you. 

You met him a few times. Over at Joel’s. He even stopped to talk to you once when Joel helped you fix a flat tire. 

“You’re Joel’s neighbor, right?” he asks. 

“Yeah,” you say, giving a small smile. “Is he here? Need to talk to him.” 

Tommy nods towards the trailer. “He’s here. Had himself a day,” he mutters. “Reckon he’ll be glad to see a face that ain’t mine.”  You swallow hard.

Walking toward the trailer. Do you knock? Just walk in? Why the hell do you feel like such an angsty teenager trying to decide all this? 

But, you knock.  Twice. 

You hear his voice through the door and step inside. “Tommy, I ain’t in the mood to–” he starts, then stops when he turns and sees you. 

You stood there. A tired smile on your face. “Shit, sorry,” he says, takin’ off his glasses. “Thought you were Tommy. He’s been ridin’ my ass all day.” 

“He, uh…warned me you were havin’ an off day,” you say. 

He shakes his head. “Ain’t nothin’ new.” 

You are silent. Can’t say anything or maybe there isn’t anything you can think to say. 

‘Cause his day was possibly about to get worse. Finding out he’s gonna be a dad again, and at work of all places, isn’t exactly the kind of news that’s gonna go over easily.

“What’re you doin’ here, darlin’?” he asks, voice low. “Don’t get a pretty girl showin’ up at my work too often. ��Specially not a neighbor who didn’t even let me say goodbye.” 

Fuck.

Panic starts to set in. A little bit of nausea too. Was it warm in here? Or are you about to pass out on the floor? Or worse, throw up for the one millionth time. 

“Can I–um–sit?” 

“Course,” Joel says, nodding toward the chair. 

You sit in the old chair. It was metal. Wobbly. But you were fidgeting, picking at your fingernails. Tryin to will yourself to just say it. You take a deep breath. 

“I’ve known for a while,” you mutter, looking at him. “Just didn’t….didn’t know how to tell you.” 

Just say it. Rip the damn band aid off. 

“I’m pregnant.” 

His face. His totally normal face that was there seconds ago. It goes blank. White as a ghost. Joel blinks once. “You’re what?” 

“It’s yours,” you blurt out, panicking. “I haven’t been with anyone in a while, and you were the last person…” 

You don’t finish the sentence. Don’t know if you can. He goes quiet. You get it. You just changed everything in his life with two words. 

It stretches on. That shocked look on his face. God knows how long ya’ll were sitting there for. 

The tick of the clock on the wall.  The sound of construction going on outside. 

He lets out a slow breath. “Well, shit.” he mutters, mostly to himself. “Ain’t usually good with words, ya know that. Sure as hell ain’t right now.” 

You don’t know where to start. If you should apologize. If you should stay quiet. This was such a difficult situation. 

“If you don’t want to be–” 

“No,” he cuts you off, quickly. “Ain’t like that, darlin’. Just surprised.” 

He pauses. “Just strugglin’ to wrap my head around it right now.” 

You get it. If someone dropped this on you at work. On a stressful, exhaustin’ day. You’d be losing your mind too. 

You’re still trying to wrap your head around the fact you’re pregnant. 

“How sure we talkin’ here?” he asks. 

“I went to the doctor,” you say. “No doubt about it.” 

Joel sighs. Running a hand over his face. Fidgeting with a pen on the desk. “I know this is a lot all at once,” you murmur. “But it’s…happenin’. I’m keepin’ the baby but I don’t expect anythin’ from you, Joel.” 

“We outta talk ‘bout this I get hom—” 

But Joel’s cut off by the door slamming open. 

“Hell Joel,” Tommy announces, steppin in, shaking his head. “Half the damn shipment’s missin’. Boys can’t do shit without it.” 

“A’right,” Joel says, getting up from his chair. “I’m comin’.” 

Tommy huffs. Muttering something as he slams the door shut behind him.

Joel looks back at you. Hand on the door. “We’ll talk more ‘bout this later.”

It’s been four days since you told him. Not like you’ve seen him. Not once. Every morning when you leave for work. His truck is already gone. You spent the whole day wondering. Did you screw up by telling him? Is this even something he’s gonna want in the long run? Maybe he doesn’t wanna be part of it. 

Between the morning sickness and teaching first graders, it’s been rough. Hard to keep up during the day. You’re sleepy half the time and so fatigued. One cup of coffee was barely helping anymore. 

Pregnancy makes it so you can only have one cup. No more. Limited caffeine. 

It’s a shitty day without it. Not like you can remember the last time you had a normal one. You figure those don’t really exist in these first few months anyway. 

But when you get home that night. Pulling into the driveway. He’s there. 

Sitting on your porch steps. Black t-shirt with the construction logo on it. 

Muddy boots. Jeans that are mostly worn and washed out. 

“Hey,” you say, walking up to the steps. 

Joel looks up at you with those hazel eyes. 

“Know it’s been a few days,” he says. “Ain’t proud of that.” “I dropped a lot on ya,” you reply. “Sorry for that.” 

You sit down next to him. It was something about it, sitting with him. Quietly on the steps. Lookin’ at the cars going down the street. 

He rests his hand on your leg. “Ya doin’ a’right?” he asks. “Feelin’ sick or…any of that?” 

Every single symptom seems to have creeped up on you. If there’s a checklist. You’ve got every fucking box ticked. But you don’t want him to worry. Don’t want him thinkin it’s his problem to fix. 

“Mostly just not feelin’ great,” you admit. “End up gettin’ up in the middle of the night. Throwin’ up. Really, Joel, it’s okay–” 

“You’re carryin’ my baby,” Joel says, eyes on you. “‘Course I’m gonna check on ya. Whether ya like it or not.” 

My baby. 

Words you didn't think you’d hear him say out loud. Words you weren’t so sure if you were ready to hear. 

“I’m just…tired,” you mutter. “Ain’t got much energy between work and this.” 

You two continue to sit on the porch.

Truth is, you don’t know much about him. He doesn’t know much about you either. 

All you know is he’s guarded. Alone. Has a grown daughter you’ve seen maybe twice since you moved in. 

Two people. Two strangers with completely different lives. And now…you’re having a baby. Together. 

“I’ll tell ya,” he whispers. “Didn’t think I’d be doin’ the whole raisin’ a baby thing again.” 

You never expected any of this either. Now you’re gonna be a…mother.

“I got an appointment comin’ up,” you say. “You can come with me. If ya want.” 

“Yeah, darlin’,” he replies, squeezing your leg a little. “Ya just let me know when.” 

Joel’s sweet. You’d expected him to be upset. Maybe even angry. But he surprised you. The way he handled it. The way he was trying his best at this moment. You reach into your bag. Pulling out the photo the doctor gave you. Handing it to him. 

His calloused fingers take it. He looked down at the small black-and-white photo. Your name printed at the top. The tiny blob of the baby in the middle.

“Crazy, ain’t it?” 

“Yeah,” you mutter. “It really is.” 

He goes to hand it back. But you shake your head. 

“Keep it,” you say. “It’s yours.” 

You stand up. Letting out a breath as you stretch. “I feel like I got hit by a damn truck. Gonna go lay down, Joel.” 

If you sat there long enough. You could’ve fallen asleep right there on the porch steps. On his shoulder. With how damn tired you felt. 

Everything felt like it was wearing you out. 

You’re almost at the door when you hear him. “Sweetheart.” 

You turn around. 

“I’m here,” he says. “Ain’t goin’ nowhere. You need anythin’—you just let me know. Kay?” 

“I know.” 

The moment you close the door. You stand there. Waiting to hear his footsteps fade off the porch. 

You wouldn’t trust anyone. Not really. Not in this situation. But for some reason, you decide to trust Joel Miller. Maybe for the first time in your life. You don’t feel alone.

My Muse

Hyunjin x fem!reader

Warnings: SMUT 18+ MDNI

Genre: Best friends to lovers, fluff, smut

Summary: Hyunjin is in love with you. His best friend. His muse. But you're totally unaware of his feelings for you, and until you've actually pushed him to the edge and all his self control shatters.

a/n: So sick with fever, and totally craving Jinnie 😅 So here we go 🤭 Forgive any mistakes, I'll edit it again soon.

It had been a long day. It usually was when you and Hyunjin took to painting in his studio - two easels facing away from each other, soft music humming from the Bluetooth speaker - it was your thing.

After having worked for more hours than healthy,  you and Hyunjin were tidying up the mess of paint tubes and brushes scattered across the table.

You grabbed a damp cloth to wipe down the table, bending over slightly to reach a stubborn paint splatter, and Hyunjin, who had casually turned around to put the little box of paints away, froze. His eyes lingered on the soft curve of your lower back, exposed as your top rode up. 

Hyunjin gripped at the paintbrush in his hand, knuckles white, taking a step back. He knew he shouldn't. You were his best friend. But you were also his… everything. 

Hyunjin was in love with you. He has been for the longest time. But you? Sweet, wide eyed and totally clueless. Sometimes he did things that screamed romantic love, like how he'd grab your arm, pulling you into a slow dance in the living room - lights dim and slow music playing. But you'd giggle and make jokes and yeah. He would deflate like a sad balloon, wishing that for once you'd understand.

It had started rather innocently. His heart fluttering softly, his insides feeling warm and fuzzy. But that had grown into a far worse condition - like him picturing pinning you against the table, kissing every inch of you, and more…so much more.

“Hyune, you’re slacking,” you teased, turning to face him with a playful grin, completely unaware of the storm raging inside him. You flicked the cloth at him, a light, flirty gesture that sent a few drops of water his way, and he dodged, laughing. 

“Slacking? I’m just… admiring your cleaning skills,” he said, his tone teasing but his eyes dark, lingering on the way you’re standing, hips cocked, one hand twirling a strand of your hair. You don’t notice, because to you, this is just Hyunjin - your dramatic, artsy best friend who’s always been a little extra. But to him, every move you make is a test of his sanity.

“Oh, please,” you laughed, stepping closer to flick the cloth at him again, this time hitting his arm. “You’re just lazy!”

You were so close now, close enough that he could smell your perfume, see the flecks of paint on your fingers, and his control was actively slipping. He grabbed your wrist to stop the next flick, his grip gentle but firm, and the contact sent a jolt through you, though you don't overthink.

“Lazy? Me?” he said, his voice dropping, a husky edge to it that you didn’t quite register.

He pulled you closer, just a fraction, and you stumbled, laughing, your free hand landing on his chest to steady yourself. His t-shirt was a little damp, because obviously he was sweating, his warmth seeping through, and you were so unaware that you didn’t realize how your touch was setting him on fire.

“Hyune, let go,” you giggled, trying to tug your wrist free, but he held on, his thumb brushing the inside of your wrist. You playfully shoved at his chest with your other hand, your fingers brushing his collarbone, he let out a low, barely audible groan.

You laughed as you twisted out of his grip and spun around, grabbing a paint roller to “threaten” him with. You waved it dramatically, pretending to chase him, and he played along, backing up with a grin, but his eyes were wild - pupils blown - and his jeans were getting uncomfortably tight.

“Come on, Hyune, fight back!” you said, laughing as you lunged forward, the roller grazing his arm, leaving a streak of blue paint. He caught the roller, pulling it - and you - closer, and suddenly you were chest-to-chest, your breath hitching at the sudden proximity, though you still thought it was all fun and games.

“Careful, muse,” he said, his voice low and rough, and you blinked up at him, still smiling. “You’re playing with fire.”

He was trying to warn you, but you just laughed, thinking he’s being dramatic, and you booped his nose with a paint-stained finger, leaving a blue dot.

“Fire? You’re more like a sparkler,” you teased, and that did it.

The combination of your touch, your smile, the way your body was pressed against his - it was too much. Hyunjin’s control snapped like a frayed thread, and he stepped back abruptly, his face flushed, his breathing uneven.

“Fuck, I…I need a sec,” he stammered, and before you could ask what was wrong, he was bolting toward the bathroom, his long legs carrying him out of the studio in record time. You stood there, confused, the roller still in your hand, paint dripping onto the floor.

“Hyune?” you called after him, frowning. “You okay?”

You dropped the roller on the table and ran after him, standing out is the bathroom door, worry flaring. 

Inside the bathroom, Hyunjin leaned against the door, his chest heaving.

“Get it together, Hwang,” he muttered to himself, running a hand through his hair, but his body had betrayed him, the bulge in his jeans painfully evident.

He has been imagining you - your laugh, your skin, the way you’d feel under him - for years now, and that playful moment had literally pushed him over the edge. He was so in love with you it hurt, but his desire was in overdrive, picturing you on that table, paint smeared across your body, his hands everywhere.

He splashed cold water on his face, trying to calm down, but it was of no use. He was too far gone, his thoughts filthy, his need for you overwhelming. He glanced at the mirror, his reflection showing a man on the verge - flushed cheeks, wild eyes, hair a mess.

“She doesn’t even know, you fool,” he groaned, gripping the sink.

He considered taking care of the problem right there, his hand hovering over his waistband, because if he went back out like this, he wasn't sure he could keep pretending to be just your friend.

Outside the bathroom door, you stood still, a little worried, a little confused. You tried calling out to him, but all you heard was the water running, and so you walked back to the studio, giving him some space. 

You started cleaning up again, humming to the music, completely unaware that your best friend was in the bathroom, fighting a losing battle. 

When he finally emerged, his hair was damp, his face still flushed, but he had pulled himself together - just barely.

“Sorry, uh… got paint in my eye,” he lied, his voice a little too high, but you buy it (because you’re you, sweet and trusting). 

“Poor baby,” you said, genuinely concerned as you reached up to check his face, your fingers brushing his cheek.

He tensed, his eyes fluttering shut for a second, and you frowned. “You sure you’re okay?”

“Yeah,” he said, his voice rough, stepping back to put some distance between you. “Just… stings a little.”

His poor heart raced, and he knew he was one playful touch away from confessing everything - or doing something he couldn't take back.

The next weekend you were back for your regular painting session. The week had been crazy. Hyunjin had dodged all your calls for coffee runs. Or your midnight cake cravings - he usually took you out any time of the day or night for satisfy your craving (even though his own craving remained sadly unfulfilled). 

He looked normal enough as you both set up your easels and dug through the paint box, choosing your colours. Normal enough. And you definitely sensed something in the way he was standing way too far away from you.

“You ok, Hyune?” You asked, setting down your things and facing him. 

“Uh huh. Good.” He said, not meeting your eyes.

“You do understand that I know you enough to know when you're not ok, right?”

“It's nothing,”

“Hyunjin. I swear I'll leave if you're gonna act like an ass -” You walked up to him, looking way too fierce for a tiny human being. “Tell me what's going on.” 

Hyunjin didn’t answer right away. His jaw was tight, his breathing uneven and he wouldn't look at you. When you reached up to turn his face towards you, your fingers brushing his skin, something in him snapped.

“Fuck it,” he muttered, so low you barely caught it. “I'm in love with you. Ok? Have been for the past ten years and I'm sick of having to pretend like it's all ok when it's not!”

You stared at him, completely shocked, but also totally confused. 

“Why didn't you say anything?” Was your only question. 

He literally had nothing to say to your wide eyed surprised, cute face. He took in a deep breath and said something along the lines of, “I swear to God-”

And he just stood there taking in deep breaths and you stood watching him. And then he said, “I'm going to kiss you.”

And before you could even blink, he was on you, his hands grabbing your waist, pulling you flush against him. His lips crashed into yours, desperate and hungry, nothing like the gentle, playful Hyunjin you were used to.

You gasped against his mouth, your hands instinctively gripping his shirt, caught off guard by the intensity.

“Hyun-” you managed, your voice a squeak, but he cut you off, kissing you deeper, his tongue sweeping against yours. Your poor brain struggled to catch up - you’d never seen him like this, never thought of him as anything but your sweet best friend - but the way his hands roamed your body, sliding under your crop top - it made your heart race.

“Been holding back too fucking long,” he growled against your lips, his voice rough, laced with a desperation that sent a shiver through you. “Tell me to stop. I'll stop and I'll not hold it against you, I promise. But, but be honest-”

You were definitely not gonna ask him to stop. Not after that, not after years of him making your heart flutter madly. So you cupped his cheeks and pulled him into a kiss again. 

He whined, one hand cupping your face, the other slipping under your top, his fingers grazing the bare skin of your waist, then higher, teasing the edge of your bra. His lips trailed down your neck, hot and urgent, his teeth grazing your skin. 

You were trembling, a mix of nerves and something new, something electric, as his hands pushed your crop top up, exposing your chest.

“Fuck, you’re so perfect,” he murmured, his voice almost a whine as he pulled your bra down, his lips finding your nipple, wrapping around it with a slow, deliberate suck that makes you gasp. You’d never felt anything like this before - your experience was practically nonexistent (because you were so hung up on your best friend) and the sensation was overwhelming - your body arching into him as your hands clutched his hair.

“Hyunjin!” you squeaked, your voice high and panicked, but there was no stopping him now. His tongue flicked against you, his lips sucking harder, and the heat pooling in your core was so intense it was dizzying. You were falling apart and you finally understood - he wasn't just your best friend. He has been wanting you, craving you, and you’ve been too naive to see it.

He groaned against your skin, his hands gripping your hips, pulling you closer as he switched to your other breast, his lips and tongue relentless.

“Been dreaming about this,” he mumbled, his voice muffled, “about you, every fucking night.”

His hands slid lower, cupping your ass through your jeans, and you whimpered, your head tipping back against the wall as your body betrayed you, responding to every filthy move he made.

“Hyun, I…I didn’t know,” you managed, your voice trembling, and he pulled back just enough to look at you, his lips glossy, his eyes blown with lust but still soft, still your Hyunjin.

“How could you not know?” he said, his voice laced with a desperate kind of affection. “I’m fucking obsessed with you. Always have been.”

He kissed you again, hard and you just melted into him, your hands tugging at his shirt.

He pushed you back against the table, the paint tubes scattering as he lifted you onto it, his hands quick and sure as they worked your jeans open. You were panting, your mind racing - part of you was still freaking out, still processing that this was your Hyunjin, but the way his fingers slid against your folds, teasing through your underwear, makes your thoughts scatter.

“Fuck, you’re so wet,” he groaned, and you blushed, embarrassed, because you didn’t even realize how much you wanted this.

“Hyun, I’ve never -” you started, but he shushed you with another kiss, his fingers slipping past the fabric, finding you with a precision that made you moan, loud and unfiltered.

Every touch felt new and intense, and he was watching you like you were a masterpiece, his eyes drinking in every reaction.

“I’ve got you, my muse,” he murmured, his voice thick with need as he kneeled, pulling your jeans and underwear down in one swift motion. You were exposed, vulnerable, and he was kissing down your stomach, his lips hot and gentle, until he was between your thighs. 

Your eyes met and he whispered a soft, “Relax,” before his tongue flicked against your clit in a way that made your vision blur. You cried out, hands gripping the table's edge, your body trembling as he worked you with a hunger that was both shocking and intoxicating.

“Hyunjin, oh my god,” you whimpered as he slipped a finger in, and he hummed in response, the sound vibrating against you, pushing you closer to the edge. Your body shook as he devoured you with so much love and need, like you were the most precious thing in the world. You felt him nibbling on your clit gently as his another slipped in and it didn't take you long to come crashing down with a cry. Your hand tugged at his hair as he kept going, drawing it all out until you were a shaking mess.

He wasn't done, though. He stood, his jeans barely holding him together, and you could see the evidence of how much he wanted you, his bulge straining against the fabric. He was panting, his face flushed, his hair a mess.

“I need you,” he said, his voice raw, no trace of negotiation left. “I need you so bad.”

You nodded, still dazed - you were pliant, trusting, even as your heart raced. He pulled you closer, kissing you so hard as he fumbled with his jeans, freeing himself, and you gasped at the sight, your nerves flaring again.

“It’s okay,” he whispered, his lips on yours, his hands guiding you. “I’ll go slow, tell me anytime you want me to stop, ok?”

You nodded again, watching him pull open a drawer on the table and fishing in it for a condom. You narrowed your eyes as he put it on (making a mental note to ask him why he had condoms in his studio). 

He just gave you a sheepish grin before lining himself at your entrance and pushing in. He was slow at first, careful - making sure that you were ok. You obviously winced at the sudden breach - and gripped his arms tight, a little shaky gasp leaving your lips.

He stilled, studying your face for any signs of discomfort. And you just shook your head and said, “I'm ready,”

“Ok,” He breathed, and started to move, his thrusts deep and steady.

But then, a moan from you had him moving faster, his face buried in your neck. You were clinging to him, as he whispered how much he wanted this, his lips finding your nipple again as he moved, sucking hard enough to make you moan.

It was too much, too fast, and you were falling apart again, your body tightening around him, drawing a choked groan from his throat as he followed. His release had him collapse against you, both of you panting, paint cans clattering to the floor as the table shook. 

For a moment, it was just you two, the studio silent except for your ragged breaths. He pulled back, his eyes soft now, searching yours.

“You okay, baby?” he asked, his voice gentle again, though his hands were still possessive on your hips.

You nodded, still processing, your cheeks burning as it finally hit you - your best friend just fucked you senseless, and he has been wanting you this whole time.

“I… I didn’t know,” you said, your voice small, and he laughed softly, kissing your forehead.

“Now you do,” he said, his smile tender but still a little wicked.

“Mhm…” You hummed, but your eyes met again. “So… are we gonna talk about why you have condoms in your studio?”

“About that -”

“You perv!”

“It was for you! Only you! I swear!”

You smiled seeing his flustered face and how he was getting worked up, while still inside you. 

“Yeah?”

“Yeah…”
