An npm module for using Karma and Coveralls with Grunt


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-karma-coveralls --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

coveralls: {
    options: {
        debug: true,
        coverageDir: 'directory name',
        dryRun: true,
        force: true,
        recursive: true
dryRun: [boolean]

Using this option you can run coverage without sending data to the coveralls service and instead writing the results to coveralls.json.

force: [boolean]

Using this option you can ensure that if there is a failure, ie: the coveralls service is down, your grunt tasks will continue to run and not terminate due to the error.

recursive: [boolean]

This option defaults to true. If it is set to true coverageDir will be searched recursively for Otherwise the subdirectories will be ignored.
