This automation programming language is gradually and consistently acquiring force nearby test automation. Because of the amazing features of the language and its similarity with Selenium WebDriver, numerous automation testers are slanted to utilize C# for mechanization testing and cross-program testing. Utilizing the Page Object Model (POM) plan design, testers can think of productive and viable test code. 

Various automation testing systems in C# guide Selenium automation testing or automated program testing. Because of the accessibility of a wide scope of test structures, numerous designers are thinking about C# for the improvement of experiments identified with cross-program testing.
