I quickly added a generic test for the ACCESS-ESM1.5 specific config tests - to just checking the tests pass without error (and also to pass the codecov CI checks..)

I ran some manual tests with an configuration to test the error messages, and that they failed when expected

It seems like there are three things bundled into one PR here ?

Yes, sorry about that! I added the tests so they covered the lines I added in the first commit. But yeah next time, I'll add the wider tests for tests in an earlier PR.

This should also close #44
