I'm not a huge fan of the pattern of scattering these utility methods all over
the test directory. I'd rather see this in the standard test_pub.dart.

Regardless of what you decide to do there, document it.

I actually prefer more tightly scoped files. test_pub is getting to be a pretty
big bag of mixed nuts.
Done.
