So, now when Cucumber executes a step of the scenario mentioned in the feature file, it scans the step definition file and figures out which function is to be called. The feature file is the essential segment of cucumber tool, which is used to write acceptance steps for automation testing. We want to support both steps. Cucumber supports Data Driven Testing using Scenario Outline and Examples keywords. We can even run the feature file to execute the test scripts written in the Stepdef file. The simplest Cucumber Expression that matches that text would be the text itself,but we can also write a more generic expression, with an int output parameter: When the text is matched against that expression, the number 42 is extractedfrom the {int} output parameter and passed as an argument to the step definition.
