Which method is used to execute tests selectively in Cucumber?

• A. tags keyword
• B. features keyword
• C. both tags and features keyword
• D. options keyword

Answer: (C)

The method used to execute tests selectively in Cucumber is through the tags keyword. Tags allow you to categorize scenarios in your feature files, enabling you to execute a specific subset of tests based on the tags you apply. When you run your tests, you can specify which tags to include or exclude, allowing for granular control over the execution of your tests.

While Cucumber also uses the features keyword to identify specific feature files to run, it is the tags connected to scenarios that allow for selective execution. Tags can be highly beneficial for organizing tests in a way that aligns with test scenarios, enabling developers and testers to run only those scenarios that are relevant to a particular testing effort.

The options keyword doesn’t exist in Cucumber's typical syntax for executing tests, which leads to it not being a correct choice in this context. Thus, using tags provides a powerful mechanism to selectively run tests based on various criteria, such as test types, priorities, or other characteristics that the team finds useful.
