When a feature file is run, Cucumber will get an instance of our ScenarioContext passed to each class by the picocontainer which will them be used by the class methods. A simple example explains the correct use of Given/When/Then: Use Given to put the system in a known state. Cucumber automatically run the complete test the number of times equal to the number of data in the Test Set; Example tables always have a header row, because the compiler needs to … Gherkin Each annotation method is defined: @Given annotation define method to open firefox and launch the application @When annotation define method to enter the username and password @Then annotation define method to reset the credential Cucumber and SpecFlow can be categorized as "Testing Frameworks" tools.

Background keyword is used to define a test case or series of steps which are common to all the tests in a feature file. Here are the arguments in favor of each: The First Person In the above code, the class is created with the name 'Steps.' The step definitions serve Cucumber as a translation of the steps we write in actions to execute to interact with the system. Cucumber hooks can come in handy when we want to perform specific actions for every scenario or step, but without having these actions explicitly in the Gherkin code.
