了解SpringBootTest中的TestExecutionListeners和BaseTest类

我正在尝试进行一些测试。 我的疑问是要针对当前运行的Test的父类TestExecutionListener和@Before的执行顺序执行@After的Order。

示例：

我有一个类，可以在测试配置文件的表中设置一些虚拟用户并将其删除。因此，我为用户相关项目创建了一个基类。 我的基类如下：

public abstract class BaseDataTest {
    @Autowired
    private UserRepository userRepository;

    private TestUserGenerator testUserGenerator;

    @Before
    public void setUp() {
        testUserGenerator = new TestUserGenerator(userRepository);
        testUserGenerator.createTestUsers();
    }

    @After
    public void cleanUp() {
        testUserGenerator.deleteTestUsers();
        testUserGenerator = null;
    }
}

我现在有两种情况：

  1. 只需插入用户，然后再从数据库中获取更多信息，并且用户存在于测试数据库中即可。
  2. 我必须插入测试用户，以后再检查特定用户，然后从当前登录用户的blocked表中提取所有用户。

对于方案1，它工作正常，因为Test类上没有TestExecutionListener批注，因此可以正确调用基类方法setUp / cleanUp，并且我的测试运行良好。我的测试课程如下：

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("test")
public class UserInsertTest extends BaseDataTest {

    @Autowired
    UserRepository userRepository;


    @Test
    public void testThatSystemHasUsers() {
        Assert.assertNotSame(userRepository.count(), 0);
    }

}

对于不起作用的情况2，因为我拥有TestExecutionListener类，并且具有WithSecurityContextTestExecutionListener类作为值，因为没有调用我的setUp方法，并且系统没有用户证明认证测试失败。 我的BlockUserTest类如下：

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("test")
@TestExecutionListeners(value = {WithSecurityContextTestExecutionListener.class})
public class BlockUserTest extends BaseDataTest {

    @Autowired
    private AppUserDetailsService userDetailsService;

    @Autowired
    private BlockService blockRepository;

    @Test
    @WithUserDetails(value = "sabrinahuff@comstruct.com")
    public void blockNoneReturnEmpty() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        User user = userDetailsService.loadUserByUsername(authentication.getName());
        List<Block> blockedByMe = blockRepository.getBlockedByMe(user.getId(), PageRequest.of(0, Integer.MAX_VALUE));

        Assert.assertNotNull(blockedByMe);
        //as i have not blocked anyone yet in test    
        Assert.assertSame(blockedByMe.size(), 0);
    }

}

我得到了

由于内部principal为null，这似乎是有效的，因为db中没有测试用户，因此以空值返回loadUserByUsername。

org.springframework.security.test.context.support.WithUserDetailsSecurityContextFactory中的方法

public SecurityContext createSecurityContext(WithUserDetails withUser) {
        String beanName = withUser.userDetailsServiceBeanName();
        UserDetailsService userDetailsService = this.findUserDetailsService(beanName);
        String username = withUser.value();
        Assert.hasLength(username, "value() must be non empty String");
        UserDetails principal = userDetailsService.loadUserByUsername(username);
        Authentication authentication = new UsernamePasswordAuthenticationToken(principal, principal.getPassword(), principal.getAuthorities());
        SecurityContext context = SecurityContextHolder.createEmptyContext();
        context.setAuthentication(authentication);
        return context;
    }

保持TestExecutionListener和测试数据生成，我如何才能通过块用户测试。谢谢！

Spring SecurityTest 

@Test
    @WithUserDetails(value = "brysonhensley@yahoo.com")
    public void test() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        Assert.assertEquals(1, 1);
    }

这似乎可行，并且在调试后，我的身份验证对象中填充了有意义的值，因此我认为是UserDetailsService bean名称。
