Error running simple test

[maratkalibek]

Hello, I wrote simple test in JUnit, but there is error during running it.

Database - MySQL


Code is

      repositoryService.createDeployment()
         .addClasspathResource("kz/maratkalibek/activiti/Process1.bpmn20.xml")
         .deploy();
      ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("financialReport");
      List<Task> tasks = taskService.createTaskQuery().processInstanceId(processInstance.getId()).list();
      for (Task t : tasks) {
         taskService.complete(t.getId());
      }
      tasks = taskService.createTaskQuery().processInstanceId(processInstance.getId()).list();
      for (Task t : tasks) {
         taskService.complete(t.getId());
      }
      Assert.assertTrue(true); ‍‍‍‍‍‍‍‍‍‍‍‍‍

error is

Hmmm the problem is not your process or unit test. It is the automatic clean up after the test has run.

Could you post your complete unit test so we can reproduce it?
