Software Development Engineer in Test (SDET) Interview Practice Test

When running a runner class in Cucumber without specifying any tags, all feature files will execute sequentially. This is because the default behavior of Cucumber is to look for all defined feature files and scenarios unless specific tags are provided to filter the execution. Tags allow for selectively running particular scenarios or features based on their assigned labels, but in the absence of tags, Cucumber assumes that the goal is to run everything available. Therefore, it's essential to understand that when no tags are applied, the comprehensive execution of all defined tests occurs, which is beneficial for covering the full breadth of functionality within the project.
