The “withWrap” part of the function name was intended to described the boolean argument. Now that the argument is self-explanatory, you could drop “withWrap” from these and other function names.

That's a good point.

Should this set *didWrap = DidWrap::No at the top to ensure that didWrap gets set to something if it is nonnull?

Minor nit - I would factor out the call to findMatchesForString into a helper to make these calls more readable (and maybe wait for each one to complete before moving on so we don't need to nest each step in the test in a new block).

Side note: I think it's a bit weird that findMatchesDone is a static variable here :/ I think we should just make it local to each test, but that could be for another patch later. Also, do we need to set it to false here? I thought since each test is run in a different process, this state should not bleed into any subsequent tests.
