The data sets to be taken into consideration shall be passed below the Examples section one after another separated by | symbol.

The tags are added to each test scenario starting with the @ symbol. Open the activation link on a browser. It could take a few weeks for a large number of scenarios. It points to the header of the Examples table. //Since the global container is the base container of the test thread container, globally registered services can be also injected. An example of use in the page objects file would be: Handling it this way allows the DI provided by SpecFlow to inject the driver that you created in BeforeScenario into the PageObject when you inject that page object into your steps file, like so: Using this pattern, that injected "GoogleSearchPageObject" will have that ChromeDriver object you initialized in the BeforeScenario method in your hooks file. This ensures that the [BeforeFeature] and [AfterFeature] hooks are executed only once for each feature and that the thread has a separate (and isolated) FeatureContext. Select Normal user addition Scenario, then click on Open additional output for this result link. 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 [BeforeFeature] public static void BeforeFeature(FeatureContext featurecontext) { featureName = extent.CreateTest . Automation logic that has to run before/after executing each feature, Automation logic that has to run before/after executing each scenario or scenario outline example, Automation logic that has to run before/after executing each scenario block (e.g. The number signifies order which means that the hook with the lowest number is run first. We shall also take the help of keyword Scenario Outline to execute the same Scenario over multiple values. [assembly: Parallelizable(ParallelScope.Fixtures)].
