Comment (by Simon Charette):

 Since da9fe5c717c179a9e881a40efd3bfe36a21bf4a6 (#20392) `TestCase`
 subclasses execution is wrapped in a transaction per-db on class setup and
 each method is wrapped in a save point per-db.

 In your case I think you'd want to disable the transaction wrapping at the
 class level so test method get wrapped in a transaction instead of save
 points. I think you should be able to achieve that by also checking that
 all connections support checkpoints in `TestCase.setUpClass()` and
 `tearDownClass()`.
