Syntax

  • Feature: this keyword signifies that what follows is a basic description or name of the feature being tested or documented.
  • Background: this keyword signifies steps that will be ran before every scenario in the feature.
  • Scenario: this keyword represents the name or basic description of a particular scenario testing the feature.
  • Scenario Outline: This keyword signifies that the scenario will run N times for every argument listed in examples explicitly passed by column name wrapped in angled brackets.
  • Examples: this keyword notes the list of static arguments that will be passed into a scenario outline.
  • Given: this keyword represents a given step, or precondition that is assumed before continuing. In the Arrange, Act, Assert paradigm, given represents "Arrange".
  • When: this keyword represents a when step, or the behavior that is to be asserted against. In the Arrange, Act, Assert paradigm, given represents "Act".
  • Then: this keyword represents a then step, or in other words, the step in which a behavior's result is validated. In the Arrange, Act, Assert paradigm, given represents "Assert".
  • And: This keyword is used in conjunction with any of the keywords above. If you have two given statements, instead of explicitly calling Given twice, you can say, " Given A And B".
