/**
 * This base TestCase class will automatically
 * 1. bootstrap Embedded JBoss
 * 2. Call static methods deploy() and undeploy() of the class at setup() and tearDown()
 *
 * If the preProcessedTest() method is used, this creates a TestSetup that will skip step 2 above
 * and instead call the static deploy() method before any test methods are run in the class.  Undeploy() will
 * be called when all test methods of the class are finished.
 *
 * This class was designed so that all tests within the class can be run at once from your IDE, or just one test method.
