For example you can get the ScenarioContext injected as parameter in the BeforeScenario hook. SpecFlow makes test automation easier by turning it into a team effort and allowing every role to better use their skills Developer Spend more time on coding feature-logic rather than debugging and explaining code Benefits for Developers Tester Right-click on Features folder. They should be thread-safe and safe to execute repeatedly. It also contains regular expression attributes. To make an analogy, think about TestInitialize and TestCleanup from MSTest framework.
