This introduces new tests to verify the callbacks on
clearCache
are being used as expected.It is difficult to verify which queue is active through the
DispatchQueue
API so the test uses setSpecific/getSpecific to associate a key/value with the queue and validate in the completion callback - thanks for the tip @designatednerd.
