contrib: break out tests into separate files for each plugin

[getify]

In addition, bundle.js needs to optionally include a test only if building with the plugin in question.

[legodude17]

Maybe you should have to files: bundle.js and bundle-test.js.

[getify]

I actually don't think the tests need to be bundled. I need to figure out how to get npm test to figure out which tests are appropriate to run or not.

[legodude17]

So one test file for each plugin, then a single test file that will run the tests that are given by some prereq? What would that be? The ones bundled? User selected? Don't know?

[getify]

Shrugs. I think maybe all plugins present... but then, someone may build a subset (supported by bundle) and want to test only those. Not sure. what to do here. That's why it's an open issue for so long.

[legodude17]

I was thinking about a --test option to bundle.js. The default would be all, but otherwise you could specify which tests you want.

[getify]

That could work. If you specify, it tests your bundle (maybe before writing to the file?) but if not, the npm test command tests all in the one big bundle.
