junit - 使用 Mockito 在 JUnit 中获取 BadRequestException

问题描述

我正在使用 Mockito 为服务类编写一个 Junit。应用程序是使用 Java 8、Spring 5 构建的。虽然我的其他测试方法运行良好，但我被卡住且无法进一步进行的测试方法除外。

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = CommerceConnectorApplication.class)
@ActiveProfiles("test")
@AutoConfigureWebTestClient
public class CommerceRepositoryDetailsTest {

  @Autowired
  private RepositoryDetails repositoryDetails;

  @MockBean
  private AsyncRunner asyncRunner;

  @MockBean
  private CommerceTenantUserRepository tenantUserRepository;

  @Test
  public void whenUpdateCartId_ThenReturnUpdatedTenantUserDetails(){
    String tenantId = "2737363";
    String userId = "763sssj";
    String cartId = "827";

    TenantUserKey tenantUserKey = new TenantUserKey();
    tenantUserKey.setTenantId(tenantId);
    tenantUserKey.setUserId(userId);

    CommerceTenantUser commerceTenantUser = new CommerceTenantUser(tenantUserKey, "xyz@abc.com", cartId, LocalDate.now());
    Optional <CommerceTenantUser> commerceTenantUser1 = Optional.of(commerceTenantUser);


    Mockito.when(tenantUserRepository.findById(tenantUserKey)).thenReturn(commerceTenantUser1);

    Mono<CommerceTenantUser> actualMono = repositoryDetails.updateCartId(tenantId, userId, cartId);
    CommerceTenantUser commerceTenantUser2 = actualMono.block();

    assertThat(commerceTenantUser2, is(commerceTenantUser));

  }
}

错误 ：-

2018-08-14 16:19:38.843  INFO 106888 --- [           main] c.s.c.c.c.s.CommerceRepositoryDetails    : Entering updateCartId@CommerceSystemDetailService

测试的主要方法：-

    @Override
    @CachePut(value = CommerceConnectorConstants.CommerceCache.COMMERCE_CACHE_TENANT_USER_DATA_MAP)
    public Mono<CommerceTenantUser> updateCartId(String tenantId, String userId, String cartId) {
        logger.info("Entering updateCartId@CommerceSystemDetailService");

        final TenantUserKey commerce = getTenantUserObj(tenantId, userId);
        Optional<CommerceTenantUser> tenantUser = commerceTenantUserRepository.findById(commerce);

        return tenantUser.map(tenantUserObj -> updateCartIdAndRefreshMap(tenantUserObj, cartId))
                .orElse(Mono.error(new BadRequestException("error in updating cart")));

    }

    private Mono<CommerceTenantUser> updateCartIdAndRefreshMap(CommerceTenantUser tenantUserObj, String cartId) {
        tenantUserObj.setCartId(cartId);
        final Mono<CommerceTenantUser> commerceTenantUser = asyncRunner
                .one(() -> commerceTenantUserRepository.saveAndFlush(tenantUserObj))
                .doOnNext(value -> commerceCacheService.refreshMap())
                .doOnError(error -> Mono.error(new BadRequestException("Error ocurred in updating cart id ")))
                .map(commerceTenantUserObj -> commerceTenantUserObj);
        return commerceTenantUser;

    }

方法updateCartId()调用另一个私有方法updateCartIdAndRefreshMap()。我的 JUnit 在updateCartId()的返回语句中失败。

请告知如何修复我的 JUnit 以测试这个特定的 updateCartId() 方法。
