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); } SpecFlow comes with some predefined hooks that are executed after some events are fired during the tests execution. We must convert a Table to a Dictionary via System.Collections.Generic package. 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. To access the context classes in a thread-safe way you can either use context injection or the instance properties of the Steps base class. A Test-Driven Development is also known as the TDD. You have to use SpecFlow+ Runner with AppDomain or Process isolation. log4net . By default, the execution order is unspecified, and they can be executed in any order.
