<h2>USE:</h2>
<p>
To use ScriptTest, enter any html you may need for your test scripts in the html box (not required). Do not worry about headers etc, the html is already set up, you are essentially just entering elements into a body.
</p>
<p>
Add as many test boxes as the Javascript snippets you'd like to test. Each editor will be treated as a separate test case. You do not need to add any loops as ScriptTest will take care of that for you (just select from the settings how many iterations you want for testing).
