How To Run A Single Cucumber Scenario Or Feature

To run a single Cucumber scenario or feature, one has to use tags. Tags are keywords prepended with an @ sign, which are inserted before a section heading.

@authentication
Feature: Authenticate user

  @login
  Scenario: User login
    ...

  @logout
  Scenario: User logout
    ...

If a tag is assigned to a feature, every scenario in it will inherit the tag. In other words, running a feature tag will run all of its scenario. Running a tag can be achieved as follows:

$ npm run cucumber-js --tags @login

Running multiple features or scenarios

To run more than one feature or scenario, simply append your tags to the command.

$ npm run cucumber-js --tags @login @logout @anotherTag
