Why I Love Get By Text

I have a confession: I've been writing browser tests lately, and my preferred approach to locators is becoming get by text or get by label.

I am aware that some of you might want to throw some full wine bottles at me now. But I stand by it.

Over the course of my career as a test automation specialist, I've worked with a bunch of web applications for which I automated browser tests. One of the most critical aspects of writing browser tests is finding good locators to hook into in order to drive the application. Naturally, since there are plenty of options there are also plenty of opinions on what kind of locator strategies to use. Typically these follow some kind pattern like this;

Use id attributes that are permanent, if you can. If you can't, then

Use data-testid or other custom attributes specifically for automation if you can. If this isn't an option then

Use class attributes, which tend to be stable. If you can't do this, then

Use CSS properties to specify elements. And if all the above aren't options, then

Use text or xpath locators or something and hope for the best.

Generally patterns like this are a good heuristic for identifying locators. However, the nature of front-end web applications has gradually changed over the past decade. Most front-ends are now generated through frameworks and not through hand-written HTML, CSS and JS. A result of such frameworks is that elements aren't always able to be directly manipulated by developers, and you need to rely on the capabilities of the framework. Browsers (and computers more generally) have gotten faster and more efficient. And lastly, tooling has evolved greatly for browser automation. Selenium WebDriver is a web standard now, and there's lots of other tools that can be used.

Based on all this progress, one would imagine that there's been progress on how to choose or use locators well with modern and maybe less-modern web apps and pages. One would be, I think, disappointed to find out there hasn't been much progress here. Finding and maintaining locators is pretty similar to how things looked many years ago. Front-end developers still hesitate to add custom attributes for testing sometimes. Newer web frameworks dynamically create elements, so id attributes are either not present or not reliable enough for automation. No one understands CSS, still.

What to do based on this state of affairs? I've been using Playwright lately for browser automation, and Playwright provides a getByText() method for finding elements. I started using it out of convenience at first and, well, I'm convinced it's a good approach. Why? Because - frankly - it works well.

The thing about text in web applications, whether that be labels next to inputs or placeholder text, is that it's actually fairly stable. Most buttons with the text Submit will continue to have the text Submit for a long time. And if the text does change on an element it is straightforward and obvious to update your tests. Plus, text doesn't tend to go away: moving from Angular to React to Vue to Svelte still means your Name field has a label of "Name" that end users will see.

One big objection to using text is localization internationalization, which can be a valid point. However, if your web app has five options for language, does that mean the logic and workflows change as well? They might, but if they don't, you can likely test one language and still feel confident in the test results. If you can't use text-based locators, then you'll have to evalutate your strategy anyway.

I am a big fan of the adage "What's the simplest thing that could possibly work". When it comes to finding elements by text, this advice seems to hold true.

Why React JS is the Best Frontend Framework in 2025

Introduction

The web development industry changes at light speed. Picking the right frontend framework is paramount for developers. Why React JS is the Best Frontend Framework in 2025? It continues to dominate due to its efficiency, flexibility, and scalability. React JS remains the most favored choice for building modern web applications, making it the go-to framework for developers worldwide. Let's dive deeper into the reasons for its success.

What is React JS?

React JS is an open-source JavaScript library for building dynamic and interactive user interfaces, developed by Facebook (now Meta). Since 2013, with the advent of React, frontend development has been revolutionized for developers to develop scalable web applications in a more streamlined manner.

Why React JS is the Preferred Framework for Frontend Development in 2025

React JS remains the top choice for frontend development through its widespread adoption, industry demand, and continuous improvements. Companies like Facebook, Instagram, Airbnb, and Netflix implement React for their web application.

Key Features that Make React JS the Default Choice

1. Component-Based Architecture

This component-based ideation provides developers the freedom to accomplish the UI canvassed in variations and reusable components, thus increasing the efficiency of the development process.

2. The Virtual DOM for Fast Rendering

React implements the Virtual DOM, which means it only changes the needed part of the UI instead of rendering the entire UI, leading to greater performance and speed.

3. One-Way Data Binding

This is a common feature that provides unidirectional data flow within the application, aiding debugging processes, and thus further strengthens application stability.

4. Reusable Components

React components are reusable across different projects, which helps in preventing redundancy and aids in faster product development.

Performance and Efficiency

Due to efficient rendering processes and optimizing updates, React works as one of the fastest frameworks. Compared to Angular and Vue, React ensures better load-time and user experience with the help of its Virtual DOM.

React and SEO Friendliness

Server-Side Rendering (SSR) by Next.js

React with Next.js makes server-side rendering possible, making it perhaps SEO and search engine visibility friendly.

React Hooks - The Real Game Changer

Hooks, introduced with React 16.8, let developers employ state and other React features without writing class components. This ultimately leads to much cleaner and easier-to-manage code.

React Native-Going Beyond Web Development

Using the same React JS code base, a developer can now create mobile applications faster for cross-platform development.

Support from Community and Ecosystem

Unlike any other framework, React with its dynamic community of developers and rich culture of libraries and tools offer undeterred support and resources to its developers.

Easy to Learn and Strong Documentation

React documentation is well structured, backed by tons of tutorials, putting it among the frameworks easy to learn compared to Angular and Vue.

Integration With Modern Development Tools

React has great integration with TypeScript, Redux, and backend technologies, making it a wonderful application in modern web development.

The Future of React JS

React continues to grow with newer features and updates to keep it mainstream and in the lead among frontend development.

Why Learn React JS at TCCI-Tririd Computer Coaching Institute?

TCCI provides expert professors for training, hands-on project learning, and career support, thus facilitating students' understanding of React JS and assisting them in attaining high-paying jobs in the industry.

Conclusion

Due to its efficiency, scalability, and the strong community backing it enjoys, by 2025 React JS remains the best frontend framework out there. If you want to create modern web applications, then learning React would be imperative!

Top Web Development Frameworks in 2023

A framework is a collection of programming tools as a fundamental "guide" for creating well-organized, dependable software and systems. The creation of online applications, including web services, web resources, and web APIs, is facilitated by web development frameworks. A web framework gives access to pre-made elements, code snippets, or templates used to speed up web development through a library. Let’s discuss the best web development frames used in 2023.

React

React JS (also known as React or React.js) is an open-source JavaScript framework for creating user interfaces (UI) and the parts that make them up mobile applications. Due to its simplicity and adaptability, React has quickly become the most widely used front-end framework in the last year. Facebook and the larger community develop it. Facebook, Skype, Shopify, Discord, Instagram, Uber, Netflix, Tesla, Walmart, and Airbnb are a few well-known React projects.

Angular

Angular is an open-source web application framework built on TypeScript. A broad user base has contributed many tools and solutions to the Angular ecosystem. According to GitHub, Angular is the second most used front-end framework and best suited for highly customized enterprise-level online applications. Companies, including PayPal, Upwork, Google, and Nike use the Angular framework.

Vue.js

Another JavaScript-based framework is Vue(Vue.js), although it offers more freedom when it comes to using HTML and CSS and the model-view-viewmodel (MVVM) architecture. Vue has a vast support network and is simple to learn. Currently, on the rise in popularity, businesses like Trustpilot, Nintendo, and Behance all employ Vue.

jQuery

The purpose of jQuery is to make event handling, CSS animation, Ajax, and DOM tree navigation and manipulation easier. jQuery may locate an HTML element within an HTML page with a specific ID, class, or attribute. We can then use jQuery to alter one or more of the element's characteristics, such as color, visibility, etc. By reacting to an event like a mouse click, jQuery may also be used to make a webpage interactive. The permissive MIT Licence governs jQuery, a free, open-source software. 77.8% of the top 10 million most popular websites. major brands, including WordPress, Facebook, IBM, and Google, use jQuery.

Bootstrap

A free and open-source CSS framework, Bootstrap, designed for front-end web development, prioritizes mobile responsiveness. It includes design templates for typography, forms, buttons, navigation, and other interface elements in HTML, CSS, and (optionally) JavaScript. With approximately 164,000 stars as of May 2023, Bootstrap is the 17th most starred project (and 4th most starred library) on GitHub. 19.2% of websites utilize Bootstrap. The layout components of Bootstrap are the most noticeable since they impact the entire web page. Every other element on the page is contained in the fundamental layout element, which is referred to as the Container. A fixed-width container or a fluid-width container are the two options for developers. The former employs one of the five specified fixed widths, depending on the size of the screen displaying the page, whereas the latter always fills the width with the website. Popular examples of Bootstrap include Lee, Fox News, Reuters, and NetGuru.

Ruby on Rails

Rails, often known as Ruby on Rails (RoR), is a full-stack framework created in the Ruby programming language and is compatible with a number of operating systems, including Mac OS X, Windows, and Linux. Model-view-controller (MVC) is the framework's foundation, and it comes with a comprehensive toolbox that includes essential capabilities for both frontend and backend issues. With the help of established patterns, libraries, and frameworks, Rails enables experts and novices to develop various functionality, such as sending an email or quickly reading data from a SQL database. This comprises several businesses, including GitHub, Shopify, Zendesk, and others.

Django

A high-level Python web framework called Django enables the quick creation of safe and dependable websites. Django, created by experienced programmers, handles a lot of the pain associated with web development, allowing you to concentrate on developing your app without having to recreate the wheel. It is open source and free, has a strong community, excellent documentation, and various free and paid support options. The introduction of Ruby on Rails in 2005 significantly impacted the design of web applications because of its cutting-edge capabilities, which included migrations, view scaffolding, and seamless database table generation. Many frameworks in other languages, such as Grails in Groovy, Phoenix in Elixir, Play in Scala, Sails.js in Node.js, and Laravel, CakePHP, and Yii in PHP, have taken inspiration from Ruby on Rails. This effect on other web frameworks is still noticeable today. Several well-known websites use Ruby on Rails, including Shopify, Airbnb, Crunchbase, Dribbble, GitHub, and Twitch.

Flask 

Python-based Flask is a microweb framework. Due to the fact that it doesn't require any specific tools or libraries, it is categorized as a micro-framework. It lacks components where pre-existing third-party libraries already provide common functionality, such as a database abstraction layer, form validation, or other components. However, Flask allows for extensions that may be used to add application functionalities just as they were built into the core of Flask. There are extensions for object-relational mappers, form validation, upload handling, several open authentication protocols, and a number of utilities associated with popular frameworks. The Flask framework is used by applications like Pinterest and LinkedIn.

Laravel

Laravel is known for its high performance, increased security, and scalability, and has many libraries for supporting development. Model-view-controller (MVC) web applications should be developed using the free and open-source Laravel PHP web framework, developed by Taylor Otwell and based on Symfony. One of Laravel's features is a modular packaging system with dedicated dependency management. Other features include several methods for accessing relational databases, application deployment and maintenance tools, and a focus on syntactic sugar. Laravel's source code is available on GitHub and is licensed according to the MIT Licence.

CodeIgniter

An application development framework, or toolkit, called CodeIgniter, is available for PHP website developers. By offering a comprehensive collection of libraries for frequently performed operations and a user-friendly interface and logical structure to access these libraries, it aims to enable you to construct projects much more quickly than you could if you were programming code from scratch. By reducing the amount of code required for a particular activity, CodeIgniter enables you to concentrate creatively on your project. CodeIgniter has been designed to be as flexible as possible so that you can work without being constrained. The framework's essential components may be modified or replaced to ensure the system operates as intended.

Conclusion

2023 has brought forth a plethora of exceptional web development frameworks that have revolutionized the industry. These frameworks have empowered developers to create robust, scalable, high-performing web applications easily. With the right framework in hand, developers can harness the power of these tools to create exceptional web applications that drive innovation and success in the digital landscape.

Introduction to Web Components

When you begin your journey as a developer, you learn that you should reuse code as much as possible. For front-end development, though, it is not so easy. When you have to create custom markup structures, they end up in being complex in style and script and using them multiple times can turn your page into a mess. Web Components, that are called the building blocks of web applications, promise to solve such problems.

Web components are a set of web platform APIs that allow us to create custom, reusable and encapsulated HTML tags for web pages and web apps. Such custom components and widgets build on the established standards, can work across various browsers, and can be used with any JavaScript library or framework that works with HTML.

Web components specifications

Web components incorporate four (in certain classifications, three) main technologies that can be used together to create versatile custom elements with encapsulated and reusable functionality:

Custom Elements

Custom elements are in essence fully-valid HTML elements, just like <div>, or <article>, but they have custom templates, behaviors and tag names (e.g. <one-dialog>) made with JavaScript APIs. They would always have a hyphen in their name, like <calendar-slider> and browser vendors have committed to create no new built-in elements containing a dash in their names to prevent conflicts. They can be used out-of-the-box with today’s most popular frameworks, including Angular, React, Vue, etc. with minimal effort. Custom elements contain their own semantics, behaviors, markup that can be checked in the HTML Living Standard specification.

Example:

class ComponentExample extends HTMLElement {    connectedCallback() {        this.innerHTML = `<h1>Hello world</h1>`;    } }customElements.define(‘component-example’, ComponentExample);

As you can see, custom elements (in this case, <component-example>) must in some way extend an HTMLElement in order to be registered with the browser.

Shadow DOM

The shadow DOM is an encapsulated version of the DOM. It isolates DOM fragments from one another, including anything that could be used as a CSS selector and the corresponding styles, in a somewhat similar to <iframe> manner. At the same time, when we create a shadow root, we still have total control over that part of our page, but scoped to a context. It is critically important as it ensures that a component will work in any environment even if the page has other CSS or JavaScript. More information on how to use encapsulated style and markup in web components can be found in the shadow DOM specification.

Example:

To attach a shadow root, we should run something like:

const shadowRoot = document.getElementById(‘shadow’).attachShadow({ mode: ‘open’ });shadowRoot.innerHTML = '    <style>    button {        color: purple;    }    </style>    <button id=”button”>Switch to use the CSS color purple <slot></slot></button>';

HTML Template

The HTML <template> element allows us to stamp out reusable templates of code inside a normal HTML flow that is not immediately rendered, but can be used at a later time when called upon. You can write a template of any shape or structure that could be created at a later time. To learn how to declare fragments of markup that go unused at page load, but can be instantiated later on at runtime you can check the HTML template element specification.

Example:

<template id=”movie-template”> <ul id=”movies”><li>    <span class=”name”></span> —    <span class=”year”></span> —    <span class=”director”></span> </li></ul> </template>

The example above doesn’t render any content until a script has consumes the template, instantiates the code and tells the browser what to do with it.

ES Modules

ES Modules is the recent ECMAScript standard for working with modules. The standardization of a module system for browsers completed with ES6 and browsers started implementing it, so that now ES Modules are supported in Chrome, Safari, Edge and Firefox (since version 60). Modules as collections of smaller components that can be reused in our application, let developers encapsulate all kinds of functionality, and expose this functionality to other JavaScript files, as libraries. The process of including JS documents in a standards based, modular, performant way is defined in the ES Modules specification.

Example:

// From component folder import { Users } from ‘../components/users.js’; import { Issues } from ‘../components/issues.js’;class Dashboard {    loadDashboard(){        // Create new instances        const users = new Users();        const issues = new Issues();        console.log(‘Dashboard component is loaded’);    } }export { Dashboard }

Benefits of web components

Web Components provide multiple benefits for developers and business.

Benefits for code:

Reusability: Once created, web components can be imported, used and reused in applications;

Readability: Compartmentalized, reusable code reduces the application size, simplified debugging and makes it more readable;

Declaration: You can more easily declare components on your page;

Composability: Shadow DOM allows composing applications with smaller chunks of code;

Extensibility: Custom elements API can extend browser elements or custom web components;

Scoping: Shadow DOM ensures DOM and CSS scoping so that styles don’t leak out and component DOM is local;

Interoperability: Native web components are interoperable at the browsers lowest (DOM) level.

Benefits for project

Brand consistency: Having your front-end application code split up into component libraries or even design systems can ensure brand consistency through the company. It also provides an additional benefit of the ability to be used by all teams, regardless of tech stack;

Cost-efficiency: Developers will have the ability to focus solely on making native reusable components, similar to LEGOs, and use these blocks in other applications across teams, which in the end saves money;

Faster deployments: Having ready-made code blocks, developers will be able to build and deploy applications more quickly. This leads to less time devoted to developing new features;

Quality improvement: As a by-product of reusing and reviewing the same code multiple times, the overall quality will improve in the course of time.

How to use web components?

To use a custom element you can simply import it and use the new tags in an HTML document. The ways to install custom elements, though can vary. Most elements today can be installed with NPM, but it is recommended to look at the README for the commands to install the specific element. NPM also handles installing the components’ dependencies. For more information on NPM, see npmjs.com.

Generally speaking, using a custom element is no different to using a <div> or any other element. Instances can be declared on the page, created dynamically in JavaScript, event listeners can be attached, and so on.

Libraries for building web components

Many libraries already exist that make it easier to build web components, including the following that we find useful:

Polymer provides a set of features for creating custom elements.

Slim.js provides data-binding and extended capabilities for components, using es6 native class inheritance.

Stencil generates standards-compliant web components.

Hybrids is a UI library for creating Web Components.

Angular provides the createCustomElement() function for converting an Angular component, together with its dependencies, to a custom element.

HTML and DOM specs already add features to support web components, letting web developers easily extend HTML with new elements with encapsulated styling and custom behavior. This proves that web components are already our present and it is time we start using them in applications.

Reposted from @womenintech - Mary Kenneth Keller (1913-1985) was the first woman in the U.S. to earn a Ph.D. in computer science. Keller played a significant role in the development of the BASIC programming language at Dartmouth College, an all-men’s institution at the time. BASIC revolutionized computer programming by opening the door for anyone, not only mathematicians and scientists, to learn to write custom software. A strong advocate for women in computer science, Keller encouraged working mothers to bring their babies with them to class as necessary. She was among the first to predict the future importance of computers and the information explosion. 💻✨ - . . @rehman_coding - Code never lies... . . . @rehman_coding . . . #programming #programmer #programmers #coding #coder #coders #developer #developers #js #javascript #java #csharp #laravel #tech #react #angular #vue #com #crypto puter #altcoin #dodgecoin #bitcoin #ethereum #cryptocurrency #blockchain #sql #html #css #python #django . https://www.instagram.com/p/BsL2H9ShjwN/?utm_source=ig_tumblr_share&igshid=1do9np1bq5sm5
