hey @jsloyer, I stumbled on your issue while trying to figure this out for myself on my own extension. I know this was from a while ago, but I figured I'd pass on the info anyways.

You need to add a test file like this to your test directory. This test looks for files in a "/test/colorizer-fixtures" directory to find a file, and then outputs the info in JSON into a new directory colorizer-results. If there's already a file in colorizer-results, it will test the current results against the previously generated results.
