Now everything is installed and ready to go, except that we need to add the … In this article we will create Selenium script and execute as Nunit. NUnit and MSTest attributes Previously, I had created this cheat sheet entry for myself. Note: Except for "FixtureBase" class,all the other classes are in the same namespace.
