Test suite

[paulirish]

I think it's time for us to add proper unit tests.

I haven't seen a test suite for a project like this before, but it shouldnt be too bad. I'm thinking a folder of input text files, with ANSI escapes and all. And a folder of expected output. Seem right?

Is there a test runner that'd work well for us?

👍 , too hard to test manually!

Ah, I now remember https://github.com/sstephenson/bats This seems close to ideal. :)

I attempted to get this going, but it's a bit tougher than expected.

For anyone curious, this points to the most mature assertion set for use with bats: sstephenson/bats#110 (comment)

I believe that Bats struggles with the combination of multiline output, ansi colors and empty newlines. As such, I haven't been able to target specific lines in the output, only just fuzzy partial matches against the whole thing.
