Fair enough.

But that's my exact concern. The more asynchronous the system under
test, the less guarantee you have about what it's doing. You *know*,
that the code under test is not doing some things, but the tests can not
prove that, because it's happening in a way the test can not look into.

Thanks,
Omair
