What is SpecFlow selenium?
Selenium is a web automation testing tool. The Selenium Web Driver allows you to interact with your web application in the same way that a human would through the user interface. You can click buttons, validate content on a screen, fill out forms, and do everything else a user might do.
SpecFlow is another tool that can be implemented on top of Selenium to help separate individual tests from the code into a more human-friendly format that anyone can read. Cucumber.NET employs the Gherkin language (given/when/then) to design tests.
