NullPointerException for Testcase

[tomi87]

I need some help to solve my problem with the correct way of writing for the following test. Because he give me the error code:

java.lang.NullPointerException
   at org.activiti.designer.test.TestProcess1.testXorFunctionality(TestProcess1.java:37)
   at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
   at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
‍‍‍‍‍

How can I write it in the right way ?

public class TestProcess1{

   @Rule
   public ActivitiRule activitiRule = new ActivitiRule("activiti.cfg.xml");

   @Test
   @Deployment(resources = { "XOR.bpmn20.xml" })
   
      public void testXorFunctionality(){
      
         Map<String, Object> variables = new HashMap<String, Object>();
         variables.put("choose", 2);
   
         TaskService taskService = activitiRule.getTaskService();
         RuntimeService runtimeService = activitiRule.getRuntimeService();
         
         ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("xorTest", variables);
      // ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceById("xorTest", variables);
      
      Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
      assertEquals("Choose 2", task.getName());
      taskService.complete(task.getId());

      task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
         assertEquals("pepare 2", task.getName());
      }
   }

Line 37 is?

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("xorTest", variables);

does the logging mention anything about the loading of the process-engine from the config file? Do you manually set the "processEngine" property on the rule? If so, the services are NOT initialized:


public void starting(FrameworkMethod method) {
    if (processEngine==null) {
      initializeProcessEngine();
      initializeServices();
    }

does the logging mention anything about the loading of the process-engine from the config file?

Do you have the sources of activiti locally? Can you debug in the "initializeEngine" method of the ActivitiRule to see what goes wrong. From the code I see, there is little that can go wrong, here…

[tomi87]

I don't know how I can do it.
I'm new and I don't know so much about this.

[frederikherema1]

How do you run the unit-test? Using eclipse or maven?

[tomi87]

eclipse.
