What is the purpose of the step definition file in Cucumber?

Steps definition file stores the mapping between each step of the scenario defined in the feature file with a code of function to be executed. 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.

What are the major advantages of Cucumber framework?

Advantages of Cucumber over Other Tools: It allows the test script to be written without knowledge of any code, it allows the involvement of non-programmers as well.

How does cucumber start its execution in the feature file?

Cucumber starts it’s execution by reading the feature file steps. As soon as Cucumber reaches the first step for e.g. Given the statement of Scenario, it looks for the same statement in the Step Definition file, the moment it finds the statement, it executes the piece of code written inside the function.

What is the definition of a feature in cucumber?

It is known as Gherkin. Gherkin is a plain English text language Feature: A feature would describe the current test script which has to be executed. Scenario: Scenario describes the steps and expected outcome for a particular test case. Scenario Outline: Same scenario can be executed for multiple sets of data using scenario outline.

Do you need a gherkin step definition for cucumber?

The only thing that matters is the step definition’s expression. When Cucumber encounters a Gherkin step without a matching step definition, it will print a step definition snippet with a matching Cucumber Expression . You can use this as a starting point for new step definitions. Consider this Gherkin step:
