/**
* PingTestPerf is a ping test, that has been written with the intention of being scaled up to run many times
* simultaneously to simluate many clients/producers/connections.
*
* <p/>A single run of the test using the default JUnit test runner will result in the sending and timing of a single
* full round trip ping. This test may be scaled up using a suitable JUnit test runner.
*
* <p/>The setup/teardown cycle establishes a connection to a broker and sets up a queue to send ping messages to and a
* temporary queue for replies. This setup is only established once for all the test repeats/threads that may be run,
* except if the connection is lost in which case an attempt to re-establish the setup is made.
*
* <p/>The test cycle is: Connects to a queue, creates a temporary queue, creates messages containing a property that
* is the name of the temporary queue, fires off a message on the original queue and waits for a response on the
* temporary queue.
*
* <p/>Configurable test properties: message size, transacted or not, persistent or not. Broker connection details.
