Countless hours are spent testing a web app to ensure its functionality is intact. Before Automation Testing, this testing fell into the domain of manual testers. They used to enact and reenact hundreds of test case scenarios on all benchmarked browsers, flagging what broke and also locating locate the source of breakage. Depending on the size of the manual testing team, an end-to-end system could take a considerable time to run its course. Since the advent of Automation Testing, testing of software can be made possible in shorter time frames. Deploying bug-free releases in that time requires diligent efforts and that is precisely why Selenium testing is integral to today’s development world. Let’s now dive into Selenium Testing and learn its idiosyncrasies. What is Selenium Testing? Selenium is an open-source tool that is used for automating the testing across various web browsers. It offers a single interface to Selenium Testers that allows them to write test scripts in various programming languages like Ruby, Java, NodeJS, Python, Perl, and much more. This testing which is done utilizing the Selenium tool is referred to as Selenium Testing.
