Turns out it was not your fault at all - when I tried to add the file, git told me it was being ignored because of .gitignore. I think line 15 is catching it.

Anyway! I can add this file, and I moved that other block of code, and I've pushed my changes in this branch:

If my fixup commit looks good to you and all the tests pass, I will merge! Thanks again James, this wasn't an easy issue for a beginner to tackle, what with the mock test data and the test suite in general, but you did it. Thanks!
