Unit Testing Javascript Code Inlined Within PHP

Question

At work I've been tasked with unit testing our Javascript code. I settled upon the Jasmine unit testing framework and began to learn how to use it when I was informed that we were now inline our Javascript code within PHP and not even using Javascript files any longer.

Can Jasmine work around this? Is there another framework that could? Should I be using a PHP unit test and a Javascript unit test? What would be my best approach?

Some example code from a fairly basic page to give you an idea:

any sort of insight would be greatly appreciated

That's a tough spot to be in (in there myself). IMO, you really need to test both, for the JS you probably need something like PhantomJS to test the actual JavaScript output from the HTTP Request. — aknosis

Aknosis - I'll look into PhantomJS and a PHP Unit Testing framework, thanks for your response! — Goose

rdlowrey- It seems like a couple people around the office have been saying this! Everything seems to be working ok outside of this issue so far though. — Goose

We've decided to split the PHP and Javascript, a prudent decision I'd say :) Thank you for the input JMC! — Goose

Best practice is to split all PHP out of javascript and Unit test each separately. In the long run, it becomes a nightmare to maintain and test heavily integrated code. Try a modularize as much as possible.

For example, here's how I would do it:

var exampleVariables = {
    'name' = <?=$name?>,
    'occupation' = <?=$occupation?>
};

unitTestableFunction(exampleVariables);
