How do you fix a flaky test?

If we suspect a given piece of code is at times too slow to the point of making a test fail, it can be made artificially slow using the sleep method to confirm the hunch: Using timing helpers can either be all that’s needed to fix a flaky test or sometimes a sign that the exercised code suffers from a race condition.
