Plugin Settings

This plugin supports the following settings, which are used by multiple rules:

• additionalCustomNames: This allows rules to check additional function names when looking for suites or test cases. This might be used with a custom Mocha extension, such as ember-mocha or mocha-each.

  Example:

  {
      "rules": {
          "mocha/no-skipped-tests": "error",
          "mocha/no-exclusive-tests": "error"
      },
      "settings": {
          "mocha/additionalCustomNames": [
              { "name": "describeModule", "type": "suite", "interfaces": [ "BDD" ] },
              { "name": "testModule", "type": "testCase", "interfaces": [ "TDD" ] }
          ]
      }
  }

  The name property can be in any of the following forms:

  • A plain name e.g. describeModule, which allows:

    describeModule("example", function() { ... });

  • A dotted name, e.g. describe.modifier, which allows:

    describe.modifier("example", function() { ... });

  • A name with parentheses, e.g. forEach().describe, which allows:

    forEach([ 1, 2, 3 ])
        .describe("example", function(n) { ... });

  • Any combination of the above, e.g. forEach().describeModule.modifier, which allows:

    forEach([ 1, 2, 3 ])
        .describeModule.modifier("example", function(n) { ... });
