Selenium is one of the top lists in the testing arena because of its plentiful advantages. It has contributed to loads in bringing this exponential transformation in the testing world and continuous development and delivery procedure. Testing automation with Selenium has quite become popular with ongoing developments in Machine Learning and Artificial Intelligence. It has initiated noteworthy transformations by opening up numerous unprecedented avenues in test automation. 

Selenium Test Automation

Selenium is one of the most preferred and portable open-source web app testing frameworks. This test automation framework utilizes a default testing domain language called “Selenese” to write test scripts. Selenium provides a single interface that enables you to write test scripts in diverse programming languages such as NodeJS, Ruby, PHP, Java, Perl, Python, & C#, among others. It comprises a varied stack of software automated test tools, all having diverse functionality that is app or project-specific. To versatile, the test system selenium has integrated various projects.

Selenium Components Are as Follows

• Se Webdriver

Se Webdriver is also called selenium 2.0, WebDriver executes testing scripts via browser-centric drivers. It consists of Library, API, and Framework. Selenium test uses Webdriver, which runs the app on distinct browsers, just like a user, whether it is on a remote or local machine. Webdriver testing the app on all key browsers such as Safari, Firefox, Edge, Internet Explorer, Chrome, and many more.

• Selenium IDE

Selenium Integrated Development Environment makes it simple to record & playback testing in the browser. It lets testers for easy cross-browser testing and debugging. This element of Selenium is a Firefox and Chrome plugin that can log ‘natural’ connections in the browser and build its code in distinct programming languages like Java, C#, Ruby, and Python, as well as Selenese (its own script language).

• Selenium Grid

Selenium Grid can reduce testing runtime—by performing varied test scripts on any number of remote devices straight away. It is known as parallel tests. The Grid is a smart server that routes commands in QA tests to browser instances on remote gadgets. The two essential elements required for this (besides testing script from tester/ client-side) are Node and Hub. 

Browsers as Well as Platforms Supported by Selenium

As mentioned in the Selenium official sources guide, here is the list of the platforms and browsers supported by Selenium:

  • Safari
  • Google Chrome
  • IE 7, 8, 9, 10, & 11 on proper incorporations of Windows 8, Windows 7, Vista, and Windows 8.1. Internet Explorer 6 is no longer supported. The webdriver supports running the browser’s 64-bit & 32-bit versions where applicable.
  • Opera
  • Firefox
  • phantomJS
  • HtmlUnit
  • iOS (with appium or ios-driver)
  • Android (with appium or Selendroid)

As a result, this trend is proposed to be widely accepted by more organizations around the globe. 

Some Critical Things to Avoid While Writing Test Scripts

As Selenium is a highly accepted and used automated test framework in existence, it is secure to assume that the majority of folks running automated testing are utilizing it. The basis of every Selenium test is the testing script. Without a perfectly-written test script, Selenium tests are bound to be ineffective and flaky, if not outright not possible to run. The faultily written test script generates extra work for testers and developers instead of making their lives simpler.

Let’s discuss some of the critical things to avoid when crafting Selenium test scripts:

• Large Test Cases with Manifold Chained Assertions: Really helpful Selenium scripts are simple and reusable to maintain. This is quite tough to do if someone is scripting large test cases that cover immense portions of the app under test at one go. The huge a test, the tougher it is to detect bugs. Apparently, scanning via thousands of test code lines to discover what went incorrect will always pose an enormous challenge. This is addressed by executing comprehensive unit testing and relying on Page Object Patterns to control code duplication.

• Inaccurate use of Sleeps and Waits: Explicit and Implicit Waits are more often used in automated Selenium tests to wait for a fixed duration before implementing a command. When used accurately, they are separately handled for testing active content, identifying web components to interact with, and tests functionalities. But, if QA experts mix Explicit and Implicit Waits, it leads to irregular timeout or waits times. This results in uneven behavior within testing. In the same way, too much use of thread Sleeps results in testing failure, and they require to be sensibly used. It is better to attain a comprehensive understanding of Selenium Wait for commands prior to creating any Selenium scripts.

• Bad Validation Practices: QA Testers generally make use of testing scripts with validation to make certain if functionality (a login page, for instance) is behaving as projected. Without validating such components, the testing script loses its purpose. A similar thing applies even when one is validating visual components for checking only if the surface-level User Interface is functioning. Visualize what happens if a user tries to put an order yet can’t as the tester did not enquire the database. 

• Automating the Incorrect Tests: Nothing is bad for a Selenium testing script than being written for the incorrect tests. If automated testing is shaped for areas that need manual tests, QA testers have to remain fix automation code rather than looking for actual bugs in the software. If someone automates the tests of new traits or has an unstable User Interface, you can expect a great waste of effort as well as time. Scripts should be written for accurate tests. Selenium testing scripts are better generated and used for automating user functions or procedures that are recurring. For instance, if a form requires to be tested by entering 500 distinct values, then it is a state perfect for automation. Likewise, each time a fresh code is added to the codebase, regression testing should be executed to make certain that adding the newest code does not malign the efficiency of the app’s present features. Yet again, testing necessitates automation.

Any Selenium script generated for automating everything will fail. Execute risk analysis of diverse components of the software, perform research on where automation will give extra outcomes, and then begin shaping scripts accordingly.

• Inadequate Testing Reporting: Without adequate reporting as well as documentation, Selenium testing is bound to fail. Imagine that an error has been detected. With no documentation, the QA expert will not be able to detect the source of the error or which software developer generated the code in which the bug/ error manifested. Accordingly, they do not understand who should scrutinize the bug or even what the intention of the code is. One label and names must test so that they are simple to direct for the team. Besides, mechanisms should be laid in place to aid easy communication amongst team members so that any irregularities can be instantly reported to the relevant personnel. Sharing the bud screenshots is also a better practice. Incorporating such practices will reorganize the testing script, allowing it to give optimal outcomes.

• Testing on a Sole Browser: Cross-browser test is imperative to the failure or success of any app or site. Perform the research, hunt market analytics, and generate a list of browser-gadget-Operating System combo that the target audience is ready to access the software from. It is a simple to use tool like Selenium for cross-browser tests. Use parallel tests for testing on various browsers, as well as boost outcomes. With growing competition in the digital marketplace, customers will not vacillate to uninstall an application or leave a site (& never return) at the primary sign of an error or bug.

In case QA specialists don’t have an in-house device lab, they can resort to cloud-based test solutions that offer real browsers to test on. This allows QA experts to scrutinize, examine and confirm software behavior in an accurate environ where potential customers or users will function in it.

To generate result-centric, productive, and sophisticated Selenium scripts, you should know what is true concerning Se command scripts. Combine the best practices with a cautious eye on the most universal reasons for script failure. It allows the formation of test cases that do accurately what they are liable to with lesser effort for the software developer.

What Is the Influence of Selenium Automated Test on QA Testing?

The software test market is ever-progressing, and so is QA testing. QA specialists across the globe know and manually express the challenges of testing software which led to the Test Automation introduction. Automated test has revolutionized the method QA test is performed. The free or open-source tools of the test would have given the specialists extra freedom to innovate and bring the finest out of the test’s skill. The concepts of Continuous Integration/Contagious Development and Agile have contributed to this advancement.

Selenium test has modified the face of automated tests for many QA testers or software developers’ teams around the world. What the Selenium Test framework chiefly does is – test the web apps and validate if it qualifies to get to the production environment and shift to the market-ready phase.

TDD (Test-Driven Development)

Another beneficial trait feature of the Selenium test is that it can expand to intricate tests such as load tests and production monitoring. Code flexibility, as well as relief to update the code, is what the QA team takes pleasure in the most. Test-Driven Development eases the developer’s efforts as the necessity to write the fresh code only arises when there is unsuccessful test automation.

Drawbacks of Selenium Automated Tests

In today’s era, free tools like Selenium might be the best test automation tool accessible today. Yet, every famous tool has its series of pros and cons. Let’s observe some of these limitations.

  •  Selenium migration threats persist. If handled perfectly, it guarantees good performance. 
  • Selenium is a great choice for web-based applications; however, it does not support mobile and desktop applications.
  • Undoubtedly, it provides cross-browser support, but the scripts to work on multiple browsers have to be written using Selenium IDE for using them with RC else; the scripts only support Mozilla Firefox.
  • It doesn’t support DDT (Data-driven testing) with manual scripts that have loops and conditions.
  • Selenium is not equipped with in-built reporting plus relies mainly on 3rd party reporting systems.
  • It does have the community back up however does not have a full-fledged or complete tech support team mitigating your glitches. It has partial assistance for image comparison.
  • Selenium test environment setup is tricky as it requires configuring various plugins & tools manually to support test automation.
