# 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:

```java theme={null}
@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](https://docs.camunda.org/javadoc/camunda-bpm-platform/7.24/org/camunda/bpm/engine/test/ProcessEngineRule.html) bean in the Spring configuration (which is injected by auto-wiring in the example above).

```xml theme={null}
<bean id="processEngineRule" class="org.camunda.bpm.engine.test.ProcessEngineRule">
  <property name="processEngine" ref="processEngine" />
</bean>
```
