Java @JUnit首先运行方法之后

我的JUnit测试用例遇到了一个奇怪的问题：JUnit首先调用

@After

方法

以下是我用于测试的抽象类：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = { TestServicePlusRepositoryIntegrationConfiguration.class })
@ActiveProfiles(Profiles.TEST)
@Transactional
public abstract class AbstractServicePlusRepositoryIntegrationTest {

}

下面是有问题的测试用例：

public class AdvertisementServiceSecurityTest extends AbstractServicePlusRepositoryIntegrationTest {
...

@Before
    public void setUp() {
        advertisement = advertisementFactory.createAdvertisement(OWNER_OF_ADVERTISEMENT_EMAIL);
        impersonator = memberFactory.createMember(IMPERSONATOR_EMAIL, Role.ROLE_BASIC_CHILDCAREWORKER);
        when(geolocationServiceMock.retrieveAddressFromReference("valid-reference")).thenReturn(new Address());
    }

    @After
    public void tearDown() {//Executed first!
        advertisementFactory.deleteAdvertisement(advertisement);
        memberFactory.deleteMember(impersonator);
    }

...

@Test(expected = AccessDeniedException.class)
    @WithUserDetails(IMPERSONATOR_EMAIL)
    public void deleteAdvertisementByIdWithInvalidMember() {
        advertisementService.deleteAdvertisement(advertisement.getId());
    }

什么会导致

@After

方法首先运行？仅供参考，我不使用JUnit3

以下是测试用例的完整源代码：

似乎在

@Before

方法中引发了异常，导致其无法完成：

tearDown

使用Spring的

@BeforeTransaction

参见javadocs，可以运行并通过测试：

@BeforeTransaction
    public void setUp() {
        System.out.println("setUp");
        advertisement = advertisementFactory.createAdvertisement(OWNER_OF_ADVERTISEMENT_EMAIL);
        impersonator = memberFactory.createMember(IMPERSONATOR_EMAIL, Role.ROLE_BASIC_CHILDCAREWORKER);
        when(geolocationServiceMock.retrieveAddressFromReference("valid-reference")).thenReturn(new Address());
    }

    @AfterTransaction
    public void tearDown() {
        System.out.println("tearDown");
        advertisementFactory.deleteAdvertisement(advertisement);
        memberFactory.deleteMember(impersonator);
    }

你能解释一下为什么你认为这个方法是在测试用例之前执行的吗？我已经添加了三个断点：设置方法中的第一个断点，拆卸方法中的第二个断点，测试方法中的第三个断点。第一个被击中的断点是拆卸断点……你能提供一个完整的可运行示例（比如使用System.out语句）来演示该行为吗？@JohnB:我正在这样做。请耐心听我说…@JohnB：我已经整理了一个略显精简的例子来说明这个问题。我怎样才能和你分享？
