> A grunt task to run yui tests with grover

## Getting Started
This plugin requires Grunt `~0.4.5`

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

```shell
npm install grunt-grover --save-dev
```

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

```js
grunt.loadNpmTasks('grunt-grover');
```

## The "grover" task

### Overview
In your project's Gruntfile, add a section named `grover` to the data object passed into `grunt.initConfig()`.

```js
grunt.initConfig({
  grover: {
    default: {
      options: {
        // Task-specific options go here.
      }
    }
  },
});
```

### Usage Examples

#### Basic Options
In this example, basic options are setup to run yui test on all files in the `test/js` directory with full logging turned on.  A test report will be created at `reports/grover.tap` and coverage information will appear in the console.

```js
grunt.initConfig({
  grover: {
    default: {
      options: {
          path: 'test/js/*.html',
          logLevel: 2,
          concurrent: 15,
          outfile: 'reports/grover.tap',
          outtype: 'tap',
          coverage: {
              on: true
          }
      }
    }
  },
});
```
