/**
 * Abstract JMock test case base class, which sets up the JavaServer Faces
 * mock object environment for a particular simulated request.  The following
 * protected variables are initialized in the setUp() method, and
 * cleaned up in the tearDown() method:
 * 
 * application (MockApplication)
 * config (MockServletConfig)
 * externalContext (MockExternalContext)
 * facesContext (MockFacesContext)
 * lifecycle (MockLifecycle)
 * request (MockHttpServletRequest
 * response (MockHttpServletResponse)
 * servletContext (MockServletContext)
 * session (MockHttpSession)
 * 
 *
 * In addition, appropriate factory classes will have been registered with
 * javax.faces.FactoryFinder for Application and
 * RenderKit instances.  The created FacesContext
 * instance will also have been registered in the apppriate thread local
 * variable, to simulate what a servlet container would do.
 *
 * WARNING - If you choose to subclass this class, be sure
 * your setUp() and tearDown() methods call
 * super.setUp() and super.tearDown() respectively,
 * and that you implement your own suite() method that exposes
 * the test methods for your test case.
