Question

我有一个@Transactional方法，我必须测试该方法在调用事务后是否失败，例如：

@Service
public class MyService {
    @Transactional
    public void myMethod() {
        // [...] some code I must run in my test, and throw an exception after it has been called but before the transaction is commited in order for the transaction to be rolled back
    }
}

这是测试班：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyApp.class)
public class MyServiceTest {

    @SpyBean
    private MyService myService;

    @Test
    public void testMyMethod() {
        doAnswer(/* some code which would call the real method, then throw an exception in order to cancel the transaction */)
        .when(myService).myMethod();
        // [...] other code that test other services when that service failed in the transaction but after its real method has been correctly executed
    }
}

您能告诉我在测试的/* ... */部分中放入什么代码吗？

您可以简单地使用invocation.callRealMethod()，然后在throw内使用doAnswer一些异常：

@Test
public void testMyMethod() {
    doAnswer(invocation -> {
        invocation.callRealMethod();
        throw new IllegalStateException();
    })
    .when(myService).myMethod();
    // [...] other code that test other services when that service failed in the transaction but after its real method has been correctly executed
}

在@Spy上调用原始方法，然后引发异常
