For example, consider the following feature file: In this example, the background steps are run before each scenario and provide a common context for both scenarios. Scenario Outline is the same scenario can be executed for multiple sets of data using the scenario outline. For example, you can use tags to group scenarios and features by feature area or by priority, and you can use the @ symbol to include or exclude specific scenarios or features when running Cucumber. You can also use an After hook to clean up test data after a scenario is executed: In this example, an After hook with the tag @delete_user is used to delete the user after each scenario that has the @delete_user tag. For example, you can use a regular expression to match a dynamic value in a step definition: In this example, the regular expression "Product [0-9]+" is used to match the dynamic title of the product page.
