Looks ok to me but, I'd prefer the official review from someone more in-domain, paging @zreyn ?

Yup, this is good. The outcome of the tests don't matter much for this. We care about the tests executing the code paths so that the sanitizers can do the runtime analysis. The tests that assert time will frequently fail because the sanitizers incur a performance penalty, but we don't want the pipeline to appear broken when it's doing what we want.
