We may execute a single test from a set of tests in the Cucumber framework using the tags idea. This is found in the TestRunner file's @CucumberOptions section. With the use of the @t keyword, we may tag a scenario in the feature file. A scenario can have one or more tags within the feature file. We can separate test scenarios with the assistance of tagging. We must pass the value within the tags argument to execute a selected test in Cucumber, and we must pass the <~tagname> value within the tags parameter to exclude a test from running.
