In this video we will add step definitions and create base step class required for all our step definitions within application test project. Right-click on the definition and select Generate Step Definitions. Close Visual Studio. This will create a .cs file with a skeleton for the test definition.

This point I think is very essential to the success of an Automation project using Specflow. SpecFlow uses regex matching groups to find the correct method, so either there is a bug in SpecFlow or a problem with the Regex statements being used in the project From what I could tell it appeared that SpecFlow was reading the double-quotes as part of the parameter, rather than a parameter delimiter.
