@方法首先由JUnit运行之后

Question

我的JUnit测试用例遇到了一个奇怪的问题：@After方法首先由JUnit调用。

这是我在测试中使用的抽象类：

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

以下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());
    }

是什么原因导致@After方法首先运行？仅供参考，我不使用JUnit 3。

似乎在@Before方法中引发了一个异常，导致它无法完成：

tearDown

使用Spring的@BeforeTransaction，请参阅此处的javadocs允许运行并通过测试：

@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);
    }
