This is great work, @DJBen, thank you! Would you want to inject the LilyPond test suite into this design? If so, would you want to do this in this PR or in a follow-up?

I would consider unifying both LilyPond and this more general score test suite. Given that LilyPond is a more specialized test group, I have the following thoughts:

• Redesign the ScoreTestSuite so that it consists of test groups, each containing various test cases.
• Turn LilyPondTestSuite into a test group

I lean towards a follow up PR, perhaps after some time as we round up edges on the ScoreTestSuite. What do you think?

I agree on all points.

I very much like the idea of test groups. The organization of those could be provenance (e.g., LilyPond, etc.) and/or genre and/or some other method.

A follow-up PR sounds like the way to go!

I decode to make test group as a follow up.
