/**
*
* Shows how to test a chain of endpoints that use SpEL expressions.
* The chain has direct input and output channels. The chain would
* be a fragment of a larger flow. Since the output channel is direct,
* it has no subscribers outside the context of a larger flow. So,
* in this test case, we bridge it to a {@link QueueChannel} to
* facilitate easy testing.
