Selenium Automated Testing Tools: Selenium Tech - Tech Trainers Online

Tricentis Tosca Tosca by Technology firm Tricentis was created with Agile and DevOps in mind. It is well-known to be a comprehensive tool for all testing needs, but it's still simple to use it jointly with any testing software that the business is already using. The same as TestComplete, Tosca supports cellular, internet, and background (just Windows; Mac and Linux with virtualization tools), doesn't require writing script but manual code writing remains potential.

online selenium training,

The sales team Will aid you with custom pricing though the reviews say it is about the other side. Considering the breadth of Tosca's capacities, the cost may be justifiable, but you can always start with a trial to be certain.

Why it is good: the experts of Tricentis Tosca Great for Constant Integration. Tosca fits perfectly in the Continuous Integration workflow. This is a contemporary approach capable of radically decreasing development time and running numerous tests a day. Employing scheduling tools, Tosca can run test cases directly from them and transfer the results back within an xml file.

As the instrument Was intentionally made to be employed by non-developers, it's simple to set up and learn, allowing you to begin automation tests right away.

Where's the catch: the cons of Tricentis Tosca Limited knowledge base. You won't Although the documentation is easy to navigate, you may end up restricted after coping with much more popular options like Selenium.

Tosca is ideal To get Agile development with integration of various CI technology available. It's a comprehensive testing tool with a low entrance point used by Accenture, Capgemini, Deutsche Bank, and many others.

Katalon Studio Katalon, constructed on Selenium WebDriver, is known as Selenium's rational and improved follow-on. It provides templates and frequent activities for keyword-driven testing, may be integrated with multiple programs for Continuous Integration, and contains a wealthy, analytics-filled dashboard.

At first glance, Katalon Studio has all other tools lack.

Why it's good: the experts of Katalon Great for both experts and non-techies. Katalon hides all of the complexities behind its interface but still allows skilled developers to attain the scripting manner.

Unified bundle. Pretty simple as you just need to download additional software if you examine on cellular (Appium + XCode/Node. js).

Katalon has a Well-organized library of tutorials together with videos and images that will help you out. Aside from the official help, you will find lots of free classes and YouTube lessons from other testers online.

Katalon Automatically transforms your testing results in handy charts to permit you to clearly see how implementation goes.

Where's the catch: the drawbacks of Katalon Poor vocabulary support. For now, you

Small (although rising ) community. Which means you are going to have difficulty finding updated posts and reviews.

Katalon is Actively employed by startups, small and moderate teams with restricted tech capabilities. Even learn software testing expert testers can locate the tool massively helpful with its long list of features and an advanced scripting mode. But if you are not utilizing its paid dedicated service, Katalon is not suitable for large businesses. Big projects require stronger and better support along with a more mature community, which Katalon can not yet provide.

UFT, originally Called QuickTest Professional, is a commercial instrument by MicroFocus which was obtained by Hewlett Packard in 2006. In its Magic Quadrant for Software Test Automation 2017 report, Gartner named it among the leaders on the current market, followed closely by Tricentis Tosca. This collaborative and easily incorporated tool lets you execute testing using both keywords and guide scripting. It supports CI tools, supplies web, cellular, and API testing, and has a smart object recognition function.

Why it's great: the experts of UFT Automated evaluations from manual. UFT makes manual Testing simpler by allowing developers to record previously manual evaluations and export them as automated ones. With its Sprinter applications, you are able to convert implementation reports to automation test instances.

Collaboration capabilities. UFT includes a Shared repository where members of you team can save artifacts, purposes, and clocks.

Where's the catch: the drawbacks of UFT Only one language supported. UFT utilizes VBScript as its scripting language. However, obtaining a reputation as one of the easiest languages to code and use with, it may not be such a major con, particularly for pros.

Cost. The tool is One of the priciest on this record, considering it doesn't allow for analyzing desktop programs like TestComplete does. Despite being less than reasonable, it can be a huge stepping stone for several developers. A year's seat-based license will cost you $2,500 and a concurrent one -- $3,500. UFT doesn't offer any group discounts though they may provide one in their customized enterprise package.

Only Windows support. Much like Several other testing tools which we have featured, UFT can't be employed on a Mac without further software.

Big groups can Leverage its cooperation and web/mobile/API testing features when working on a bigger project. To gain from UFT and justify its price, you need an established testing framework or has to be prepared to set one up.

Watir Despite its open Origin and fundamental character, Watir (Web Application Testing in Ruby) can be used by such huge companies as Slack, Yahoo!, and HomeAway.

Why it is great: the pros of Watir Selection of languages. Watir is just one the Few tools which allows writing scripts in Ruby programming language. Ruby is quite popular for testing since it is user-friendly, simple to understand, and quick to code with. However, if Ruby is not your language of choice, there's also a means to use Watir. Script with Java or .NET and leverage Watir's simplicity with its sister-software: Watij and WatiN.

Where's the catch: the drawbacks of Watir Could possibly be too straightforward. Watir doesn't try However, it can only be utilised in combination with other tools.

Small neighborhood. You will find Not a lot of complaints regarding the software online but there's not enough written complete. Not only is it hard to find fellow developers, the documentation and also donated content is limited to exactly what Watir lists on its website.

Ruby programmers Will find Watir really enjoyable to use (unless we're talking about Watij or Watin). As you can see in the list of its users, companies of any size can successfully execute it into their testing efforts. If you'd like flexibility and are building your testing toolkit, Watir may be worth a try.

Ranorex Ranorex is One of the most expensive and most comprehensive resources we're covering now. It supports net, background (Windows only), and cellular testing, a lengthy list of technologies and languages to choose from, automation both for inexperienced users and innovative crawlers, and personalization with third party frameworks.

Why it is good: the pros of Ranorex Selenium WebDriver integration. You are able to make Selenium WebDriver in the Ranorex environment and leverage the capabilities of the greatest automated testing framework. Such close integration allows Ranorex to correct all of pain points Selenium nevertheless has.

Where's the catch: the drawbacks of Ranorex No Mac support. Ranorex is Yet another framework that doesn't run on Mac OS and doesn't allow for testing Mac apps.

Brands like Siemens, Lufthansa, Cisco, Dell, and IBM trust Ranorex to automate their testing. With this tool, you might have an all-in-one environment which could be easily enlarged with more popular technology. It may not be the initial choice for a small development team, but companies with big budgets may safely invest in Ranorex.

If you are Interested in a more comprehensive description, read our post focused solely on Ranorex.

Final Takeaway There is a whole lot to Consider when choosing a testing software since most of it is costly or requires extra learning. Utilize our wikipedia guide to filter different options and find the ones your team would really like to use. Ensure you request free trials of proprietary tools to permit your testers to ease in the workflow until the official testing begins.

Let's quickly Recap the important points you and your staff need to think about when deciding upon an automation tool:

Programs and languages. As Possible See, not all options offer a wide range of scripting languages to select from, so it might be a fast no from one to the tools that don't provide your favorite technology. The market is especially little for Mac users, so you may wish to think about getting a virtualization program.

Coding skills. You definitely Want some flexibility in regards to your testing staff. Even if you're not yet planning to encourage less proficient testers to your team, the time might come when you would like your professional programmers to work on harder projects. Select a solution that provides this liberty.

Continuous Integration. CI is Becoming a standard in the development and testing world so it's better to focus on Tools which were constructed to work easily in an Agile environment. See that of Your preferred scheduling tools they support and what additional capacities your Team can make use of.

The Beginner’s Guide to Web Scraping with Python & Scraper Tools

A rundown of what you’ll need for Web scraping, what you might need When Scraping with Python & software, and what you don’t need.

Web scraping is the great shortcut for anyone looking for a large amount of data from specific websites. The term ‘Web scraping’ encompasses the use of a ‘crawler,’ which is something that can navigate from webpage to webpage, and even subpage to subpage within a webpage; ‘spiders,’ which extract data to the extent that the web owner deems legally permissible, and ‘scrapers,’ which may refer to the entire function of getting a machine to collect and store data for you.

By data, we do not mean a html file or two: scrapers can extract millions of data points in a short amount of time. Even better, they can be instructed to extract specifically the type of data that is being sought after.

This is, in many cases, how such massive datasets are built: no human can collect data at a fraction of the rate and efficiency that a machine can. This is the essence, is what data scraping is when people talk about web scraping.

But first, know that from any single personal computer, there is a steadfast limit to data scraping capabilities. The computational power needed to scrape data at an industrial level requires servers and data centers. This is also why many of the services listed below have pricing options. With the ones that don’t, the barrier comes from the robots protocols,

So, before you starting scrapping, Please take “Web Scraping Protocols” seriously at first!

Web Scraping Protocols

No matter what tools you use for Web scraping, there are customary protocols websites put in place. Failing to abide by these protocols can have a few different negative results. If the site is small enough, scraping at a high volume could impact their server could come across as a server attack, which could have legal ramifications. Medium-sized or larger-sized websites would be less susceptible to this, but there are other consequences instead.

API

If the websites, has an API, then using the API is encouraged. But scraping is more about extracting raw data from webpages, so using an API technically collects data using an entirely different method.

In any case, there are restrictions in what you can scrape, how often you can scrape, and the size of what you can scrape. As you learn about data scraping you may become familiar with the terms workers or spiders (defined later). These will need to follow those guidelines, but where can those guidelines be found?

/robots.txt.

Wherever information exists on a network of webpages under a single domain, the larger website usually has a landing page with instructions on what web scrapers can and cannot do on their websites. This information can commonly be found under the URL of the homepage, followed by a ‘/robots.txt’.

For example, Facebook, the social media network known for having more restrictions than its peers, marks all of the actions that are forbidden at facebook.com/robots.txt. Here’s a snippet of some of the things they do not allow you to scrape, taken straight from their own ‘robots.txt’ subpage. This is also a good place to check if the website contains a sitemap. Some do, some don’t, but if there is one, the scraper’s job gets a whole lot easier.

Note that this doesn’t mean scraping this type of data from this particular website is impossible (or from any website, for that matter). It simply means that the administrators have made it immensely more difficult in a number of ways: easier to get IP banned, harder to use simple, popular web scraping tools, among other barriers. Of course, these things can always be circumvented to some extent with some programming chops.

IP rotation

Your IP address could get banned pretty quickly for failing to acknowledge the rules laid out by the websites. To avoid this I suggest you use rotating proxies for web scraping, Now there are lots of residential proxy services offer IP rotation for scraping and web crawling, you can easily set up IP rotation via those rotating proxies providers, here is a sample for Smartproxy Python code.

# In this example a query to `example.com` is performed from a random IP. import urllib.request import random username = 'USERNAME' password = 'PASSWORD' entry = ('http://customer-%s:%[email protected]:7000' % (username, password)) query = urllib.request.ProxyHandler({ 'http': entry, 'https': entry, }) execute = urllib.request.build_opener(query) print(execute.open('https://ipinfo.io').read())

Also, Premium proxy providers like Luminati.io, offer easy to use API and advanced Luminati Proxy Manager (LPM) to handle the IP rotation for web scraping.

There are mainly two ways to scrape online, The one is using Python for Web Scraping, the other is using developed web scraper tools, let me introduce what’s needed in detail.

Web scraping Toolkits and Essentials using Python

In any case, the first two packages below are incorporated into the majority of web scraping efforts in Python, I would imagine. They work together seamlessly, and both provide invaluable tasks for web scraping.

Beautiful Soup

Beautiful Soup, installable via pip or conda as ‘bs4,’ is an invaluable package for data scraping. It’s useful because of how easily can be used to manipulate the scraped data, extracting from a typical web page what is needed, and leaving out what is not needed.

As workers crawl from par to par extracting data, they need instructions on what to download. Without instructions, they’ll download the entire thing, which would be too inefficient, clunky and noisy to ever be practical.

Thus, Beautiful Soup tells a scraping tool which specific data points to extract from a webpage — for example, the entry within the cells of a column from a table.

There are far better tutorials elsewhere for those experienced in Python who wants to write their own scripts with Beautiful Soup to their preference. (Insert hyperlink). However, there are also many scripts publicly available for common extractions made on a HTML/CSS/JS webpage.

Requests

If you already use Python, chances are you already have ‘requests,’ installed. If not, do so immediately because its usefulness is remarkable, even outside the scope of this subject. In short, requests allows you to interact with web pages in a number of useful and flexible ways.

Requests can interact with webpages, crawl an entire sitemap of a certain webpage, and even log in when prompted, as Beautiful Soup extracts the necessary data. It’s the script’s tour guide to the internet: taking it where it needs to go, granting it access to places it could not get to on its own, and moving from place to place as needed, providing information on the site and sitemap all the while.

Parcel

The parcel is like Beautiful Soup in functionality with data scraping. Simply put, It directs the scraper to the piece of data it wants, just as Beautiful Soup does. It claims to fame is that it can automatically navigate through XPath and other common CSS containers where data is often hidden.

Beautiful soup can do this too, however, with Beautiful Soup, the script has to be written so that Beautiful Soup knows where to find data hidden within Xpath.

You only have to find one example of data within Xpath on a webpage, but it requires right-clicking the page, clicking ‘inspect element’, and going through the divs in order to find where one example of the data is hidden under. Here’s an example of a script I wrote doing just that, where I actually did have to use Selenium(discussed later):

That ‘td’ was where the data was hiding under an Xpath ‘tr.’ Once I found that, the soup did the rest.

However, Parcel can skip the step of first finding the element, because it can do so on its own, according to this section of its documentation. What appears to necessarily be the case is that the package is bulkier than Beautiful Soup, and may cause slowdowns, but it offers a great deal of more functionality.

It may be better for beginners, although Beautiful Soup is fairly simple as well. Try both and see which one suits you. But for starters, here’s a publicly available crawler demo using requests and Parcel.

Better yet, here’s a site with a number of links to scripts using and explaining Parcel. Since Beautiful soup has been around for ages, there aren’t as many ready-made allocated scripts as it’s found here.

JSON

JSON as a Python package all likely be the most efficient way to save the scared data. The ubiquitous ‘pandas’ package offers the same functionality and deserves mention here as well. Using the built-in ‘re’ package, the script will need to write the scraped data to a file and save that file somewhere on the computer.

Selenium

Selenium is clunky and inefficient but can serve an important purpose if a web page is written in a way that the programs previously mentioned don’t understand. Selenium isn’t a scraper of any kind, but can be used for navigating a scraper to where it needs to go in a pinch. Selenium is a web browser condensed into a Python package.

It requires a driver, usually a ChromeDriver, which is the Google Chrome browser it’ll use. What this means is that when you run a script using selenium, a browser of your choice automatically opens, and can click certain parts of the page, enter keystrokes into certain forms, among other things, all on its own.

It’s very cool to watch, but for web scraping, its main purpose is to navigate the web scraper to a certain area of a webpage where the desired data is located. It’s an if-all-else-fails sort of mechanism since the packages aforementioned can handle the majority of web pages.

youtube

Scrapy

The problem with many of these tools is that they can be a hassle. With Scrapy, Visual Studio 14.0 is required, which you can get by downloading Visual Studio Build Tools. Extended requirements like these increase the odds of encountering difficulties.

The specifics of the programming environment, each of its packages, and whatever machine or server you’re working with can affect compatibility. Note, however, that Mac and Linux have no problem downloading Scrapy with PyPi. If you’re unfamiliar with this process, here’s what your terminal should look like:

Scripts that take advantage of Scrapy’s built-in crawling and data wrangling tools can be found all over Github, Stackoverflow, and public resources. Many of them, in fact, most of them, might not be as simple as running them from a terminal right out of the box. Therefore, for non-programmers, or for programmers on hiatus, the software can come in handy,

Scraping with software

There are a few different types of web scraping software tools out there to fit certain needs. Some require a little programming knowledge, while others will require none at all.

Some will have larger capabilities than others (for example, scraping multimedia, i.e. PDF, images, audio and video files). Let’s go over some of the more popular tools available.

Orange - Free Open source data mining software

Orange, the free data mining site found here as well as on Github, is personally my favorite tool when it comes to scraping from particular sites like Twitter.

Its main menu is a visualization of the roadmap in which you will build and implement the entirety of the process. Here’s an example of the workflow for one data mining project I did, just to illustrate the organizational capability of the software.

Using Orange for data scraping comes with a few benefits. First, storing, processing, and saving the data becomes incredibly simple. Short and informative trials are publicly available with instructions on how to do this. The software must abide by the terms of conditions of third parties, which is a burden when it comes to web scraping.

With scraping Twitter, for example, you will need an API key — find out how to get one here (anyone can get one), but using API limits the amount of data allows for scraping over a certain amount of time. An advantage, on the other hand, is that Orange allows their users to implement any script they’d like into the workflow, so everything mentioned above can be incorporated into Orange.

In the software, you will find an option to download extensions, including a data scraping extension. After you do that, scraping becomes as simple as adding the widget to your workflow.

Octoparse: freemium web scraping program

Octoparse is a mostly-free web scraping program available to every major OS. Since it offers premium packages to industries that can afford them, the software is excellent at what it can do.

Unlike other software that’s free for a very very limited amount of scraping power, Octoparse offers a generous package to it’s free users: unlimited pages per crawl, 10 crawlers at a time, and 10,000 records per export. The number of records is the make-or-break limit to the free plan: depending on the project, 10,000 entries could be either more than enough or nowhere near enough.

Regardless, it’s as effective as the Python packages listed above, and perhaps even more so. Their product overview does not exaggerate its capabilities. Just be aware of the limitations.

Paid web scraper tools

There is web scraping software that’s easy to find, but not easy to stomach paying for. These programs are suitable for businesses. The pricing is exorbitant for an individual project, but you do get what you pay for, such as,

Import.io

mozenda.com

heliumscraper.com

ParseHub.com

All get rave reviews, but all cost a pretty penny. Since I have no experience with them, I will not cover them, but the choice is yours. Just know they are out there.

Beware: 100% Free Web Scraping software almost never do as promised!

The most professional, iciest, and competent methods of web scraping is to do t using hand-programmed scripts using a machine with a server or GPU with high computational power. There are hundreds of data scraping programs out there, just see a quick search on Sourceforge:

If the descritis programs like these bast capabilities that seem unrealistic, chances are they are unrealistic. Always check if there are healthy, recent and recent updates, whether the reviews back up what the developers say the software can do, and that there are a healthy number of weekly downloads. These programs that don’t pass such criteria are probably not malicious, but they may just turn out to be junk.

So, there are two routes to take with regard to web scraping, crudely speaking. The programming, scripting route, which offers more freedoms, more personalization, and more customization. Then there are software routes, which offers ease-of-use and extra computing power.

The viability of either option depends on the amount of programming one wishes to do versus the amount of paying out of pocket one wishes to do. As discussed, this is inevitably the case with web scraping software that actually works.

Web Scraping using NODE JS with Projects from scratch ##CouponUdemygratuit ##FreeUdemyCourses #JS #Node #Projects #Scraping #Scratch #Web Web Scraping using NODE JS with Projects from scratch Web scrapping is the Data Science technique of gathering or storing useful and public information from websites in a suitable format like spreadsheets that can be used later for any purpose. It basically removes the burden of copying the data manually, instead it provides an automated way to do it. The data extraction is done from websites using some sort of a code written called “scraper” which takes the a Web URL, parses the HTML DOM of that site and then return the result which we can save in some format say CSV for future use. The data that we parse can be in form of texts, images, package names and their corresponding prices, videos and contact information like email, name, phone numbers and so on. This course is built in NODEJS that is light weight, efficient, and scale-able due to its non-blocking I/O and event driven. The main advantage of node is that its asynchronous in nature which means that you don’t have to wait for a request to complete before making another one which in turn provides a very high performance. This course is made in so much easy way so that one who doesn’t have any knowledge of NODEJS can easily understand and hence build own scrapper in NODEJS. We are using Selenium which is automation testing tool that provides various elements and methods to interact with HTML DOM in order to parse the website. Who this course is for: Data Scientists who want to create their own real world Data Set Anyone who wants to be a professional Web scrapper Anyone who wants to scrape data from any website Anyone who wants to understand the basics of node Anyone who wants to understand how to write XPATH Anyone who wants to interact with HTML DOM 👉 Activate Udemy Coupon 👈 Free Tutorials Udemy Review Real Discount Udemy Free Courses Udemy Coupon Udemy Francais Coupon Udemy gratuit Coursera and Edx ELearningFree Course Free Online Training Udemy Udemy Free Coupons Udemy Free Discount Coupons Udemy Online Course Udemy Online Training 100% FREE Udemy Discount Coupons https://www.couponudemy.com/blog/web-scraping-using-node-js-with-projects-from-scratch/

Hey Redditors,I decided to write this post (which is the 1st part of a multi-part guide) to explain how you can automate several business tasks through Python, I've been a python developer for 2 years and I've done that for my self and clients successfuly through the years, enough about me, let's get to the real stuff .Learning Python:The first thing you will have to do is to learn the basics, I won't teach you the basics here, because there's already a gazillion courses and tutorials out there for free, however I will give you some insights on what you need to learn and where to save youYou can quickly learn the basics of python through the Code Academy course, you won't need to learn OOP (Object oriented programming, for newcomers that's just a fancy way to build advanced programs), Here is the stuff you need to know at least :Variables (Integers/Decimals (floats), Strings, and Booleans)Lists and handling them (adding, removing, sorting)Conditions, and loops (How to repeat something until a condition is met or how to run a thing if a condition is true)FunctionsDictionaries and JSONThat's all you need, most books and tutorials cover this and more, here are the best I've tried when I got started:The code academy python course : You can go through all of what I talked about in a day or lessDive into python : In depth free online bookAutomate the boring stuff with python This is a book available for free online, it's a classic, it goes from the basics upto handling complex files and data your business may haveOne of these will help you getting your hands dirty with python, finishing the Code academy course is more than enough to start writing scripts to automate your business.The tools to automate your businessSo once you get the basics of python, you are ready to stop wasting time on tedious and repetetive tasks like:Uploading some files to some cloud storage or website on a regular basisDownloading some files every hour,day,month,you name itWorking with large set of dataExtracting infos from some websites every X amount of timeBuilding a bot for messenger, Twitter, FacebookSending daily reports or alerts by email,sms, or phone callsAnd anything that you think it's wasting your time and should be automated. In this post, I will show you the tools you need, the tricks and the ressources you nedd to do each of these tasks,Let's start with the first one:Getting data you need from a website:Let's say you need to check regularly prices of your competitor and email them to yourself, every hour,3 hours, day, month, you name it.It's easy to do this, as long as your competitor have a simple website that is not single page, single page are a little bit harder to get data from, but I will show you how you do that soon.Before getting into the details, let's see how accessing websites work actually, when you type www.website.com in your browser bar, he will send a request, an HTTP request to that website, this request contains some data, like the type of browser and device your are trying to access that website from, your credentials for example if you're trying to login into a webpage and few more data, the server on the other side, contains the page you want to access, he will recieve that request, validate it (in most cases) and if everything is alright, he will send you back the web page which is in a special format (language), (HTML webpage), your browser can understand HTML and turn it into a beautiful interactive web page, web developers do and you should too, you don't need to learn every single piece of it, but learning the basics is great and here is a nice tutorial for thatNow, let's go back to getting data from your competitor website, it's a website so it doesn't escape the rule, it's written in HTML and when you send a request (your browser does), you will recieve that HTML back, now we will use some Python modules, exactly two modules : requests and BeautifulSoupRequests is a library, it contains a lot of very useful functions to send requests and getting the HTML back, to install requests type this in your command line\terminal : python -m pip install requests bs4, bs4 is short for BeautifulSoup 4 .BeautifulSoup is a library that let you handle the HTML and analyze it to extract data from it.Now you are ready to go, I will send you to this tutorial to check how to use them, I'm writing currently an in-depth tutorial on Medium, you can follow me so you get notified once it's out!How to scrape a single page website (loads data through JS) : The problem if you use first method is that if the website loads data dynamically through JS is that you won't get that data in your HTML, so you need something that stimulate your browser(Firefox, Chrome, Opera etc). There is a tool out there called Selenium, it can emulate any web browser you want just by setting up the right one, in 3 lines you can open automatically your browser and play with that website, getting the HTML after data is loaded through JS, typing into forms and much more.Here is the link to selenium-python documenntation which is very nice: Selenium docsThat's all for the first part, as I told you, I will write in depth tutorials for each task, step by step on medium, right now it's empty, you can follow me here.In the next Part we will talk about the best modules for each task. Stay Tuned !Hope you liked it, if you have questions, leave them in comment or PM me. Otherwise, I'm available so if you want something automated and you don't have the time to learn how to do it, you can PM me, I've been doing this for a couple of years now.

New Post has been published on http://automated-360.com/qtpuft/automate-angular-applications/

How to automate Angular applications with UFT?

(adsbygoogle = window.adsbygoogle || []).push();

Recently software industry has shifted drastically in terms of adopting the refined and improved approaches like Waterfall model to DevOps model or from traditional testing to being involved into early phase of development(shift left). With all these approaches application development technologies has also been changed rapidly. AngularJS is one of the rapidly adopting framework which provides faster development with rich user experience. Now here is the challenge for automation tools to be on top of supporting these changes and have automation tools filled with arsenal to easily take down and automate the tests. It has been observed that automation engineers are moving out from automation tools like Unified Functional testing TestComplete as these tools lag to provide limited support to these rapid changes and every time we see a new tool/framework coming and capture the arena.

What is Protractor?

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser interacting with it as a user would.

see more @ protractortest.org

Protractor is most recommended framework for AngularJS applicationsbut this also comes with limitation and many of the times its bit irritating. Debugging is a great challenge in Protractor for testing of particular module in Protractor you need to run your complete suite again & again. So I thought to move out from the league and try UFT. Check out the all new UFT 14.0. It has been improved a lot and if you leave cost it has all the features that an automation engineer desires. So I tried and can very much say that we can automate angularjs application with UFT.

Before we go in detail to understand how UFT started supporting Angular Based Application the first question that will come is “what add in you will need to select to ensure that Angular JS feature is enabled?“

The answer is no complex: “You need to just select .Net Add in for this.There is no dedicated Add in created for this support.”

Let’s See How to Automate Angular applications

To extend the support for Angular JS support HPE has added few more locator to identify the web objects in it list.These are xpath and css properties which are considered as backbone of Selenium protractor tools.To utilize these properties follow the below steps :

Launch the application in chrome.

Right click on the element for which you need to see the property of the webpage and select the inspect option

After identify the unique property of the element you can try the expath or css in the console. Step 4.After cross checking the xpath or css in the console you can use them in your script as below :

Browser(browsername).Page(PageName).TypeOfObject("css:="&expression) or Browser(browser name).Page(Page Name).TypeOfObject("xpath:="&expression).

To explain the above steps lets take the example of Upworkcom which has the Angular JS components like the “Search the Jobs” text-box.

Before we go ahead the first question most of you is how to confirm the application has angular component or not.For this just right click on the object and check if the element tag has property starting with the keyword “ng”.In the below snapshot you can see that the input tag has an property name as ng-model which tells us that the application is AngularJS application.

Step #1

Launch the application in Chrome.We are going to see how we are going to insert the value in “Find Freelancers” text box highlighted in Red in below picture

Step #2

Right click on the “Find Freelancers” textbox and click on Inspect option which will open the below window panel highlighting the object.

(adsbygoogle = window.adsbygoogle || []).push();

Step #3

For the “Search Freelancers” text box now analyse the blue highlighted part in above picture.We see it has nameid ng-model property.Generally id is unique property for each element.So lets try id to find the element. Below snapshot give the side by side way to writing the xpath and css in console.

xpath : $x(“//input[@id=’q’]”)

css: $x(“input[id=’q’]”)

Step #4

Use the xpath or css in your script as below :

In case of CSS:

objCSSLocator="input[id='q']" Browser("browser").Page("Page").WebEdit("css:="&objCSSLocator).Set "Automated360"

In case of xpath:

objCSSLocator="//button[@id='search-box-el']" Browser("browser").Page("Page").WebEdit("xpath:="&objCSSLocator).Set "Automated360"

In case above two methods don’t work don’t feel left out as UFT has added flexibility for you to fire Javascript directly using the RunScript method.

Browser("browser").Page("Page").RunScript("document.getElementById("btnSecurity").Click();")

The above link will click directly on the web button with id given as ‘btnSecurity’ . GetElementsByID is just one of the way.There are multiple other methods on which object identification take place. For more details refer to w3 schools javascript tutorial

I have tried various permutation and combination and these 3 ways has helped me to overcome all the challenges of automation of angular JS application via UFT.

Try this approach and in case of any issue feel free to contact us. Let us know your views on this. Do you have any other idea or tool which you feel would be easy please comment.

Till then Happy Learning !!!

Reviews:

“The course is very complete and the contents are well explained by the instructor, however, the audio quality of some videos and the code indentation/organization/conventions could be much better.” (Emerson Delmondes)

“Pros: -The instructor knows what he is talking about. -Responds back to questions. -Lots and lots of content. -A good pace to the course -A wide spectrum to the content that reaches past WebDriver. A little bit of java, cucumber, testng, appium…. Cons: -Production quality. I think they were mainly recorded while conducting training classes. The audio differs and in one lecture (24.189) is absent totally. I did notice some code errors and possible the wrong code posted in a couple of areas. The course would benefit from polishing. Overall: Definitely well worth the time and money. The sheer amount of content (30 ish hours) is impressive. The inclusion of different tools and how they compliment WebDriver a nice bonus. The knowedge of the instructor is evident. My background:16 years in automation testing using Mercury interactive , IBM function / load testing tools and Empirix functional / load testing suite. Currently porting over to WebDriver and jmeter.” (Dhann)

“All the topics whatever is explained here is well explained, trainer will answer all your doubts. Good course for a beginner. Best best way of explaining. I suggest this to everyone who is looking for selenium.” (Supriya)
