/**
 * A JUnit Rule that embeds an ActiveMQ Artemis ClientConsumer into a test. This JUnit Rule is
 * designed to simplify using ActiveMQ Artemis clients in unit tests. Adding the rule to a test will
 * startup a ClientConsumer, which can then be used to consume messages from an ActiveMQ Artemis
 * server.

 * public class SimpleTest {
 *     &#64;Rule
 *     public ActiveMQConsumerResource client = new ActiveMQProducerResource( "vm://0", "test.queue" );
 *
 *     &#64;Test
 *     public void testSomething() throws Exception {
 *         // Use the embedded client here
 *         ClientMessage message = client.receiveMessage();
