This is my servlet that is invoking a workflow and it is using a workflow model.

I am unable to create a stub for the workflow model in the testcase for the servlet.

I am using a mock workflow model but it is returning null or throwing exception.

The servlet code that starts workflow provided below.

 

WorkflowSession wfSession = workflowService.getWorkflowSession(session);        

WorkflowModel wfModel = wfSession.getModel("/var/workflow/models/dam/dam_download_asset");

WorkflowData wfData = wfSession.newWorkflowData("JCR_PATH", "/content/dam/we-retail/en/features/cart.png");

wfSession.startWorkflow(wfModel, wfData);

 
 
Testcase code below:
 

@rule

public AemContext aemContext = new AemContext(ResourceResolverType.JCR_OAK);

@Mock

WorkflowServiceworkflowService;

@Mock

WorkflowSessionwfSession;

@Mock

WorkflowModel wfmodel;

@Before

public void setup() {

 Mockito.lenient().when(workflowService.getWorkflowSession(resource.getResourceResolver().adaptTo(Session.class))).thenReturn(wfSession);

Mockito.lenient().when(resolverFactory.getServiceResourceResolver(this.serviceParams)).thenReturn(aemContext.resourceResolver());

wfmodel=workflowService.getWorkflowSession(resource.getResourceResolver().adaptTo(Session.class)).createNewModel("/var/workflow/models/dam/dam_download_asset");

 

The last line in the test case is throwing error. I don't know how to create the stub for the model.

Hence it would be highly helpful if I get the details to create the workflow-model stub in the junit test case.

Hi,

 

Try below code

 

@Mock

private WorkflowService mockWorkflowService;

 

@Mock

private WorkflowSession wfSession;

 

@Mock

private WorkflowModel workflowModel;

 

@Mock

private WorkflowData wfData;

 

setup method:

 

MockSlingHttpServletRequest mockRequest = aemContext.request();

mockRequest.addRequestParameter("path", "{add the page path}");

aemContext.registerService(WorkflowService.class, mockWorkflowService);

Mockito.when(mockWorkflowService.getWorkflowSession(Mockito.any(Session.class))).thenReturn(wfSession);

Mockito.when(wfSession.getModel(Mockito.anyString())).thenReturn(workflowModel);

Mockito.when(wfSession.newWorkflowData(Mockito.anyString(), Mockito.anyString())).thenReturn(wfData);

One last issue I am facing at the end of the servlet doget method I am closing all of the resoure resolver sessions like beow

 

               try{

                       json.addProperty("success", true);

                     json.addProperty("destination_path", path);

                    response.setStatus(SlingHttpServletResponse.SC_OK);

                    response.setContentType("application/json");

                    response.getWriter().write(new Gson().toJson(json));

                    log.debug("TrashcanServlet Response 200 OK  with response text: {} ", new Gson().toJson(json) );

                } catch (TrashcanException e) {

                    log.error("Error occurred:", e);

                    try {

                        json.addProperty("success", false);

                        json.addProperty("errorCause", e.getReason());

                        response.setStatus(SlingHttpServletResponse.SC_OK);

                        response.setContentType("application/json");

                        response.getWriter().write(new Gson().toJson(json));

                    } catch (Exception ex) {

                        log.error("Error occurred:", ex);

                    }

                } catch (Exception e) {

                    log.error("Error Occurred: ", e);

                } finally {

                    if (workflowResourceResolver != null) {

                        try {

                            workflowResourceResolver.close();

                        } catch (Exception ex) {

                        log.error("Error occurred:", ex);

                        }

                    }

                    if (userResourceResolver != null) {

                        try {

                            userResourceResolver.close();

                        } catch (Exception ex) {

                        log.error("Error occurred:", ex);

                        }

                    }

                }

            } else {

                try {

                    response.sendError(HttpServletResponse.SC_NOT_FOUND, "Missing payload parameter");

                } catch (Exception ex) {

                    log.error("Error occurred:", ex);

                }

Due to all of resourceresolver sessions being closed by my code I agetting this exception in the test case, (even though my doget method is completed)

22:22:52.422 [main] WARN  o.a.s.j.r.i.h.j.JcrResourceProvider - Unable to revert pending changes.

javax.jcr.RepositoryException: This session has been closed.

Any idea to get resolve this exception.

 

            }
