FYI, here is access to the mock queue I inject into the code during the unit tests. In addition to working around the limitation with the QueueFactory (because my Queue provider in test mode returns "new MockQueue();" instead of "QueueFactory.getDefaultQueue();", the mock provides accessors that allows the tests to verify that the expected tasks have been inserted into the queue.
