grunt-simple-mocha

A simple wrapper for running tests with Mocha. It's pretty much a cleaned up and plugin-ized version of this helpful Gist by johnkpaul.

If you're looking to run client-side specs with PhantomJS, you might be interested in grunt-mocha.

Installation

1. Install this grunt plugin next to your project's Gruntfile.js with:

   npm install grunt-simple-mocha --save-dev
   

2. Then add this line to your project's grunt.js gruntfile:

   grunt.loadNpmTasks('grunt-simple-mocha');
   

Usage

In your Gruntfile.js:

grunt.initConfig({
  simplemocha: {
    all: {
      src: ['test/**/*.js', '**/*.spec.js']
    }
  }
});

// For this to work, you need to have run `npm install grunt-simple-mocha`
grunt.loadNpmTasks('grunt-simple-mocha');

// Add a default task. This is optional, of course :)
grunt.registerTask('default', 'simplemocha');

Now, you can just run grunt simplemocha in your shell to run the tests. That's it!

Advanced Mocha Options

All options parameters are passed directly to Mocha. Therefore, you can use these options to configure how Mocha runs.

• ui name "bdd", "tdd", "exports" etc
• reporter reporter instance, defaults to mocha.reporters.spec
• globals array of accepted globals
• timeout timeout in milliseconds
• retries number of times to retry failed tests
• bail bail on the first test failure
• slow milliseconds to wait before considering a test slow
• ignoreLeaks ignore global leaks
• fullTrace display the full stack-trace on failing
• grep string or regexp to filter tests with

The Gruntfile configuration would look like this:

grunt.initConfig({
  simplemocha: {
    //
    // These are passed directly to the mocha constructor. See:
    //   https://github.com/mochajs/mocha/blob/master/lib/mocha.js#L56-L74
    //
    options: {
      ui: 'bdd',
      reporter: 'tap',
      globals: ['window','document','$','should'],
      timeout: 3000,
      retries: 2,
      bail: false,
      slow: 2000,
      ignoreLeaks: false,
      fullTrace: true
      grep: 'users',
    },

    all: { src: ['test/**/*.js'] }
  }
});

Running tests

Run npm install && npm test
