    UnitTesting and jBPM pageflow

    Markus Wolf Newbie

      Hi,
      I want to write a testcase for each of my use cases. I have some use cases realized witz jBPM and now I'm wondering how to create a test case for a condition node in my pageflow. Any hint on that?

          It's definitely possible, but I don't know how to make it pretty. Here's an example from one of my tests:

          log.info("Begin testing initial mapping");
           setViewId(MappingViewId.APPLICABLE_FIELDS.id);
           invokeMethod("#{catalogMapping.beginForInitialMapping()}");
          
           Pageflow pageFlow = Pageflow.instance();
           assert pageFlow.getNode().getName().equals(MappingViewId.APPLICABLE_FIELDS.node)
           : "found " + pageFlow.getNode().getName();
           log.info("current view-id is #0, nodename is #1", pageFlow.getPageViewId(), pageFlow.getNode().getName());
           pageFlow.navigate(getFacesContext(), "continue");
           assert pageFlow.getNode().getName().equals(MappingViewId.SELECT_FILE.node)
           : "found " + pageFlow.getNode().getName();
           setViewId(MappingViewId.SELECT_FILE.id);
           log.info("current view-id is #0, nodename is #1", pageFlow.getPageViewId(), pageFlow.getNode().getName());
          
           setValue("#{catalogMapping.uploadFileInputStream}", new ByteArrayInputStream(CsvData.SMALL.getBytes()));
           setValue("#{catalogMapping.uploadFileName}", "master.csv");
          
           // Verify that the merchant is there
           Merchant merchant = (Merchant) lookup("merchant");
           assert merchant != null: "no merchant!";
          
           pageFlow.navigate(getFacesContext(), "submit");
           // the #{catalogMapping.initForInitialMapping()} should now take place in the pageflow

            Thanks for your help. I'll give that all a try on monday. :)

              It does work, but you really have to carefully simulate the browser to make it work. Note that those methods are all in SeamTest (now no doubt in BaseSeamTest). You'll find methods there to set request parameters and other things that simulate the browser.

                I think there is bug in testing(mock) environment (propagation of conversations with pageflow does not work)

                  The pageflow testing does not work for me. On subsequent requests the pageflow is lost and set to null.
                  Below is my code. Anyone can give me a hint on how to do this the correct way? There are no examples in seam releases or even cvs.

                  String id = new NonFacesRequest("/public/register.xhtml") {
                  
                   @Override
                   protected void beforeRequest() {
                   setParameter("c", "1");
                   }
                  
                   @Override
                   protected void renderResponse() throws Exception {
                   Contexts.getSessionContext().set("person", new Person());
                   Contexts.getSessionContext().set(
                   "soapMailingJobCollectionAccess",
                   mailingJobCollectionAccess);
                   Contexts.getSessionContext().set("soapMailingJob", mailingJob);
                   // setValue("#{campaign.id}", 1);
                  
                   Pageflow pageflow = Pageflow.instance(); //<-- Here the process instance is null (correct)
                   pageflow.begin("register"); //<-- Here the process instance is 'register' (correct)
                   assertEquals("register", pageflow.getNode().getName());
                  
                   assertEquals("/public/register.xhtml", getRenderedViewId());
                   }
                  
                   }.run();
                  
                   id = new FacesRequest("/public/register.xhtml", id) {

                   assertTrue(validateValue("#{person.mobile}", mobile));
                   assertFalse(isValidationFailure());
                   }

                      If, as Denis says, that bug exists, then it's not going to work!

                        Since JBSEAM-1000 does not allow be to post a comment on this I'll do this here:

                        Here is a part of my logfile related to this problem:

                          Possibly this is caused by missing AbstractSeamJsfListener or ContextFilter, since test cases are not executing inside of a webapp. But both classes above call 'handleConversationPropagation' where the pageflow is validated and the conversation is restored (but I'm a noob to seam).

                            Markus Wolf Newbie

                            Nope, the phase listener is registered and called, but I don't see the method call to afterRestoreView().

                              Ok, got it running! :)
                              I have to call a method on my component annotated with @Begin(join=true, pageflow="name") to start the pageflow AND converstation as long running.
                              The problem when calling the Pageflow.instance().begin() is that there is no long-running conversation, at least in my case. I have set the pageflow start directive in my pages.xml which does reside in another project for unit tests and is only available when deployed in a container environment.

                              Hope this does help anyone having problems.

                                hi
                                i am getting the same problem. I'm also making a test class for the pageflow.Its a simple pageflow-definition

                                Code :

                                <start-page name="page2" view-id="/page2.jspx" >




                                </start-page>

                                </pageflow-definition>

                                Here is pages.xml

                                Code:

                                <!DOCTYPE pages PUBLIC

                                <page view-id="/page2.jspx">
                                <begin-conversation nested="true" pageflow="submit2"/>



                                I'm getting the error while doing the Pageflow.instance().begin()

                                My converstaion gets start when i am on page3.jspx while i am starting the pageflow from the page.jspx.

                                I am only making the simple java file rather than the junit test case.
                                My purpose is to extract the CurrentPage and the NextPage.

                                Could you provide the sample test code for this pageflow.

                                Thanks,

                                  Can you tell me how to read this xml . Is it read internally by the seam?

                                  I had made the entry in pages.xml

                                  
                                  <!DOCTYPE pages PUBLIC

                                   </page>
                                  </pages>
                                  
                                  


                                  Can you provide the sample test code for this submit2.jpdl.xml

                                  Here i need to find out the current page,current node and the next page.
                                  I tried like the jbpm way to read the submit2.jpdl.xml but with no result.

                                  
                                  ProcessDefinition pageflowDefinition =Jbpm.instance().getPageflowProcessDefinition("submit2");
                                  
                                  


                                  Can anybody provide the sample test code for that. i m in urgency..

                                  thanks,

                                    I would think as for me your pages.xml isn't processed. Therefore you need a method in your beans annotated with @Begin(join=true, pageflow="name").
                                    This method should be called when you start your unit test in a NonFacesRequest instance.
                                    That should be all to get you running. I'll post my code later on when I'm at office.

                                    BTW:

                                    <start-page name="page2" view-id="/page2.jspx" >
                                     <transition name="yes" to="page3">
                                     </transition>
                                    
                                     <transition name="back" to="start"></transition>
                                     </start-page>

                                    This does not look leagal to be, since you do not define a node 'start' in your jpdl.
