Spring-Based Testing

When integrating with Spring, business processes can be tested very easily (in scope 2, see Testing Scopes) using the standard ASEE Flow testing facilities. The following example shows how a business process is tested in a typical Spring-based unit test:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:org/camunda/bpm/engine/spring/test/junit4/springTypicalUsageTest-context.xml")
public class MyBusinessProcessTest {

  @Autowired
  private RuntimeService runtimeService;

  @Autowired
  private TaskService taskService;

  @Autowired
  @Rule
  public ProcessEngineRule processEngineRule;

  @Test
  @Deployment
  public void simpleProcessTest() {
    runtimeService.startProcessInstanceByKey("simpleProcess");
    Task task = taskService.createTaskQuery().singleResult();
    assertEquals("My Task", task.getName());

    taskService.complete(task.getId());
    assertEquals(0, runtimeService.createProcessInstanceQuery().count());

  }
}

Note that for this to work, you need to define a ProcessEngineRule bean in the Spring configuration (which is injected by auto-wiring in the example above).

<bean id="processEngineRule" class="org.camunda.bpm.engine.test.ProcessEngineRule">
  <property name="processEngine" ref="processEngine" />
</bean>
