Safari comes in second place and Mozilla Firefox in third. Thus, it is no longer enough to test the compatibility of the web application on a single Browser. The Selenium 4 WebDriver helps the developers test the web application’s compatibility on multiple browsers and browser versions.

Thus, the multi-browser support of Selenium 4 is one of its crucial features that will drive the future testing market.

4. Support Across Multiple Operating Systems

Similar to the browsers market, the operating system market has also changed drastically over the years. Currently, more than 50% of the desktop OS market is dominated by windows. It is followed by Mac in second place and Linux in the third.

Therefore, you must ensure that the web application performs seamlessly on these operating systems. Selenium WebDriver helps the developers test the web application’s functionality on multiple operating systems simultaneously.

With the new update, Selenium has added various new features to increase the efficiency of the testing process. With the help of this testing mechanism, you can ensure that the web application remains accessible to a wider user base.

5. It is Very Easy to Implement

With the earlier versions of Selenium, the developers had to spend a lot of time in the setup and implementation process. It was also a very complex process and required proper training.

However, with Selenium 4, the setup process has been completely removed. Also, this means that the developers can directly start the testing process without wasting time. Selenium WebDriver also allows the developers to test the web application’s functionality from the browser.

Thus, it is one of the most accessible tools for test automation. It also added new features to improve the time efficiency of the test environment.

6. Selenium 4 Supports the Reusability and Integration of Codebase

With the earlier version of Selenium, the developers had to create separate test cases for every testing scenario. Thus, the developers had to invest a lot of time before implementing the test cases. Selenium 4 solves this issue by ensuring the usability of a massive portion of the codebase.

Using Selenium 4, the developers also can test the test cases’ functionality and reliability. Selenium 4 also allows the developer to import physical test cases from other automation tools and frameworks. Thus, developers no longer waste time creating and testing test cases.

7. Immense Flexibility

Test management is one of the essential features to increase the efficiency of automation testing. Selenium 4 helps to improve test efficiency by providing various features like refactoring and regrouping of test cases. The developers can use this feature to implement multiple changes in the test environment.

For instance, they can make quick changes to the source code, minimize duplication, Reduce complications and improve the maintainability of test cases.

The developers can use all of these features to complete the test cases while remaining within the comfort zone. These are the primary reasons why Selenium is considered one of the most flexible tools for automation testing.

8. Support for Parallel Testing And faster Market Release

During the early years of software development, the testers had to conduct all the test cases one by one manually. This was a time-consuming process for Complex applications that required various test scenarios. Selenium 4 added a new feature known as parallel testing to solve this issue.
