Verify exact strings in tests

This approach gives us two things:

1. Exact strings are verified, rather than more loosely checking for
   a substring
2. Should the string change in future, these tests no longer have to
   change. The purpose of them is to verify that some constant is
   returned, but they don't care what that constant actually contains.
