Bridge the gap between non-technical and technical people by collaborating on executable specifications. Executing tests in the other threads is blocked until the hooks have been fully executed on the first thread. To add the definition of the step in SpecFlow, the C# language is used. The step definition above can now be written as: [When ("I perform a simple search on {string}")] public void WhenIPerformASimpleSearchOn(string searchTerm) { var controller = new CatalogController(); actionResult = controller.Search(searchTerm); } The status of the execution shows as Not Run as the tests have still not been executed. I did that and it worked like a charm. However, I see both got executed for each scenario defined. The execution order of hooks for the same event is undefined. It is mostly used to build automation tests for projects built in .NET. I will leverage on the test example from the first article from the series where we built a test for converting Kilowatt-Hours to Newton Meters.

Also the static memory state is isolated. If the test passes, create the second test. Execution Behavior [BeforeTestRun] and [AfterTestRun] hooks are executed for each individual test execution thread (AppDomain or process), so you can use them to initialize/reset shared memory. We shall create a new C# class library. TDD is done for system and integration testing as well. Also, you can specify the tag scoping in the steps' attribute constructor.
