    Testing method with Conversation.instance().begin(true, false);

    jmchiaradia Aug 28, 2009 7:43 PM

      Hello, I am using testNG to test my Seam components.


      I'm having problems to test a component that init a conversation.


      The test fails when the conversation start:




      public abstract class UseCase implements Serializable {
(...)
        public final UseCaseConstants begin() {
                if (!this.active) {
                        this.active = true;

                        //HERE FAILS THE TEST:
                  Conversation.instance().begin(true, false);

                        Conversation.instance().changeFlushMode(FlushModeType.MANUAL);
                        this.initialize();
                        return UseCaseConstants.SUCCESS;
                }
                return UseCaseConstants.ALLREADY_STARTED;
        }
(...)



      Here is the test:


      public class UseCaseTest extends SeamTest {
        
        @Test
        public void testBegin() throws Exception {

                new ComponentTest() {

                        protected void testComponents() throws Exception {
                                // Begin OK
                                assert invokeMethod("#{useCaseManager.beginUC(new UseCase())}")
                                                .equals(UseCaseConstants.SUCCESS);
                        }

                }.run();
        }
}




      Could anyone help me?


      Regards,
      Chaira
