SpecFlow Installation and Setup
What is SpecFlow?
SpecFlow is an open-source .NET tool for automated testing that lets you write specifications using 100%-Cucumber-compatible Gherkin syntax, and has a number of advantages over Cucumber itself.
SpecFlow seems to be the most popular BDD tool. There many other tools and some of them are easier to set-up.
