### Question:
RMContextUtils { public static String generateUUID() { return org.apache.cxf.ws.addressing.ContextUtils.generateUUID(); } protected  RMContextUtils(); static String generateUUID(); static boolean isServerSide(Message message); static boolean isRMProtocolMessage(String action); static RMProperties retrieveRMProperties(Message message, boolean outbound); static void storeRMProperties(Message message, RMProperties rmps, boolean outbound); static AddressingProperties retrieveMAPs(Message message,
                                                    boolean isProviderContext,
                                                    boolean isOutbound); static void storeMAPs(AddressingProperties maps, Message message, boolean isOutbound,
                                 boolean isRequestor); static String getRMPropertiesKey(boolean outbound); static ProtocolVariation getProtocolVariation(Message message); static void setProtocolVariation(Message message, ProtocolVariation protocol);  }### Answer:
@Test public void testGenerateUUID() { control.replay(); assertNotNull(RMContextUtils.generateUUID()); }
