# Intermediate Guide (browser version)

This guide details using Blanket.js with a custom adapter to run Blanket with a test runner other than QUnit (ex. Jasmine), and covers some of the configuration options available.

It is assumed that you have already read the Getting Started guide.

To begin you will need:  
* an existing test runner (including the test library script)
* source files
* tests for those source files

NOTE: PhantomJS and other third-party JS runtimes may not support synchronous XHR requests.  If this is the case you cannot use the `data-cover-adapter` or `data-cover-reporter` attribute.  You will need to include a separate script tag for the reporter/adapter directly below the Blanket script tag.


1. Download [Blanket.js](https://raw.github.com/alex-seville/blanket/master/dist/qunit/blanket.min.js) or `bower install blanket`

2. Download a Blanket adapter for your test runner.  Currently there are adapters for [Jasmine](https://raw.github.com/alex-seville/blanket/master/src/adapters/jasmine-blanket.js) and (browser based) [Mocha](https://raw.github.com/alex-seville/blanket/master/src/adapters/mocha-blanket.js).

3. Reference the script and adapter in the testrunner HTML file as follows:
    ```<script src="blanket.min.js" data-cover-adapter="jasmine-blanket.js"></script>```

4. Add a `data-cover-only` attribute to avoid having to add `data-cover` to each script you want covered.  You can pass the filter value as a string to match, an array of filename, or a regular expression (add a double slash to the start, i.e. `data-cover-only="//.*/"`):
    ```<script src="blanket.min.js" data-cover-adapter="jasmine-blanket.js"  
        data-cover-only="['source1.js','src/source2.js']"></script>```

5. Open the test runner in the browser.  The coverage details will be appended below the test results.

6. If you will always be using the adapter, consider making a [custom build](https://github.com/alex-seville/blanket/blob/master/README.md#roll-your-own) of blanket (i.e. `dist/jasmine/blanket_jasmine.js`).
