"""Tests for package version collection
Unfortunately, we're somewhat limited in what we can test because we only get the versions of things being used at runtime, and this package sits rather low in the dependency chain so there's not usually a lot of other packages available when this test gets run. Therefore some of the tests are only checking that things don't explode, since they are incapable of testing much more than that. """
