A Grunt task for running mocha test suites in parallel

Getting Started

This plugin requires Grunt ~0.4.5
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-mocha-parallel --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-mocha-parallel');

The "mochaparallel" task

Overview

In your project's Gruntfile, add a section named mocha_parallel to the data object passed into grunt.initConfig().
grunt.initConfig({
  mocha_parallel: {
    options: {
      args: function(suiteName) {
        return [];
      },
      env: function(suiteName) {
        return process.env;
      },
      report: function(suite, code, stdout, stderr) {
      },
      done: function(success, results) {
      },
      mocha: './node_modules/.bin/mocha',
      concurrency: os.cpus().length,
    },
  },
});
