mocha-gherkin-ui v0.1.0

Making Gherkin language use with mocha Easy

Mocha Gherkin UI is a Gherkin/Cucumber syntax UI integration for Mocha testing framework.

Allows you to:

• Use common Gherking language to define your features and scenarios.

Feature('some feature', () => {
  Scenario('some scenario.', () => {
    Given('some precondition', () => {});
    And('another precondition', () => {});
    
    When('stimulus', () => {});

    Then('postcondition', () => {});
    But('another postcondition', () => {})
  });
});

• Allows you to define special tags to identify your Features or scenarios and filter them in execution

Tag('critical', 'JIRA-1145')
.Feature('some feature', () => {
  Scenario('some scenario.', () => {
    ...
  });
});

Feature('some feature', () => {
  Scenario('some scenario.', () => {
    ...
  });
  Tag('critical')
  .Scenario('some scenario.', () => {
    ...
  });
});

• And, allows two test execution skip patterns on fail based on the Gherkin language:

Moderated (configured by default) Will allow all complementary steps execution to let you see complete scenario from a main step and will skip the subsequent main steps (Given, When, Then)

    Feature: some
      Scenario: some
        ✓ Given prec
        ✗ And 2nd prec
        ✓ And 3rd prec
        ✗ And 4th prec
        ✓ But 5th prec
        - When stimulus
        - and another stimulus
        - Then postCond
        - But another postCond

Absolute: (Concept introduced by @asyncadventures at mocha-steps )

    Feature: some
      Scenario: some
        ✓ Given prec
        ✗ And 2nd prec
        - And 3rd prec
        - And 4th prec
        - But 5th prec
        - When stimulus
        - and another stimulus
        - Then postCond
        - But another postCond

Original: (The one you are used to)

    Feature: some
      Scenario: some
        ✓ Given prec
        ✗ And 2nd prec
        ✓ And 3rd prec
        ✗ And 4th prec
        ✓ But 5th prec
        ✗ When stimulus
        ✗ and another stimulus
        ✗ Then postCond
        ✗ But another postCond

Installation

NPM:

npm install --save-dev mocha-gherking-ui

Usage

Indicate mocha you are going to use mocha-gherkin-ui as a mocha integration using --ui mocha-gherkin-ui option on mocha command:

mocha --ui mocha-gherkin-ui path/to/my/tests

If you like specify which type of skip do you prefer moderate, absolute or original (By default moderate):

mocha --ui mocha-gherkin-ui --mochaGherkinUiSkipMode absolute path/to/my/tests 

And be able to filter by the tags you gave, the test you want to run

mocha --ui mocha-gherkin-ui --mochaGherkinUiSkipMode absolute --mochaGherkinUiFilterTags critical,system1,anything path/to/my/tests
