 If there is no official test covering the functionality you're after, then you can write your own. You might want to submit a pull request to the web-platform-tests repo too!

+First you'll want to `npm install`. To run all the tests, use `npm test`, which just calls `node test/runner`.

+Using `test/runner` directly, you can slice and dice which tests your want to run. Usage is as follows:

+```
+test/runner --help
+Run the jsdom test suite

+Options:
+-s, --suites     suites that you want to run. ie: -s level1/core,1/html,html [string]
+-f, --fail-fast  stop on the first failed test
+-h, --help       show the help
+-t, --tests      choose the test cases to run. ie: -t jquery

 ## Contextify
 
 [Contextify](https://npmjs.org/package/contextify) is a dependency of jsdom, used for running `<script>` tags within the page. In other words, it allows jsdom, which is run in Node.js, to run strings of JavaScript in an isolated environment that pretends to be a browser environment instead of a server. You can see how this is an important feature.
