/**
*
* Shows how to test a router; the router is configured to route to direct
* channel names. The configuration would
* be a fragment of a larger flow. Since the output channels are direct,
* they have no subscribers outside the context of a larger flow. So,
* in this test case, we bridge them to {@link QueueChannel}s to
* facilitate easy testing.
