Unit testing 单元测试

当集成 Spring 时，使用标准的 Activiti 测试工具类是非常容易的对业务流程进行测试。 下面的例子展示了如何在一个典型的基于Spring单元测试测试业务流程：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:org/activiti/spring/test/junit4/springTypicalUsageTest-context.xml")
public class MyBusinessProcessTest {
  @Autowired
  private RuntimeService runtimeService;
  @Autowired
  private TaskService taskService;
  @Autowired
  @Rule
  public ActivitiRule activitiSpringRule;
  @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());
  }
}      

注意对于这种方式，你需要在 Spring 配置中（在上文的例子中它是自动注入的）定义一个 org.activiti.engine.test.ActivitiRulebean

<bean id="activitiRule" class="org.activiti.engine.test.ActivitiRule">
  <property name="processEngine" ref="processEngine" />
</bean>
