Use a testsuite

[daurnimator]

We need tests!

I'm not sure what the best testing tool/infrastructure will be here.
Do people have suggestions?

I'd suggest using mocha. It's really easy to utilize and I'm experienced in writing cases :)

If my current project utilizing this works well I'll look into write a few basic test cases for the project!

From what I've heard, Mocha and Chai are two good libraries.
