java.lang.AssertionError: Status expected:<200> but was:<404> in Junit test

Question

我想為 Rest api 創建 JUnit 測試並生成 api 文檔。 我想測試這段代碼：

休息控制器

@RestController
@RequestMapping("/transactions")
public class PaymentTransactionsController {

@Autowired
private PaymentTransactionRepository transactionRepository;

@GetMapping("{id}")
    public ResponseEntity<?> get(@PathVariable String id) {
        return transactionRepository
                .findById(Integer.parseInt(id))
                .map(mapper::toDTO)
                .map(ResponseEntity::ok)
                .orElseGet(() -> notFound().build());
    }
}

存儲庫接口

public interface PaymentTransactionRepository extends CrudRepository<PaymentTransactions, Integer>, JpaSpecificationExecutor<PaymentTransactions> {

    Optional<PaymentTransactions> findById(Integer id);
}

我試圖用 mockito 實現這個 JUnit5 測試：

@ExtendWith({ RestDocumentationExtension.class, SpringExtension.class })
@SpringBootTest(classes = PaymentTransactionsController.class)
@WebAppConfiguration
public class PaymentTransactionRepositoryIntegrationTest {
    .....
    private MockMvc mockMvc;

    @MockBean
    private PaymentTransactionRepository transactionRepository;

    @BeforeEach
    void setUp(WebApplicationContext webApplicationContext,
              RestDocumentationContextProvider restDocumentation) {

        PaymentTransactions obj = new PaymentTransactions(1);

        Optional<PaymentTransactions> optional = Optional.of(obj);      

        PaymentTransactionRepository processor = Mockito.mock(PaymentTransactionRepository.class);
        Mockito.when(processor.findById(Integer.parseInt("1"))).thenReturn(optional);       

        this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
              .apply(documentationConfiguration(restDocumentation))
              .alwaysDo(document("{method-name}", preprocessRequest(prettyPrint()), preprocessResponse(prettyPrint())))
              .build();
    }

    @Test
    public void testNotNull() {
        assertNotNull(target);
    }

    @Test
    public void testFindByIdFound() {
        Optional<PaymentTransactions> res = target.findById(Integer.parseInt("1"));
//        assertTrue(res.isPresent());
    }

    @Test
    public void indexExample() throws Exception {
            this.mockMvc.perform(get("/transactions").param("id", "1"))
                .andExpect(status().isOk())
                .andExpect(content().contentType("application/xml;charset=UTF-8"))
                .andDo(document("index-example", preprocessRequest(prettyPrint()), preprocessResponse(prettyPrint()), links(linkWithRel("crud").description("The CRUD resource")), responseFields(subsectionWithPath("_links").description("Links to other resources")),
                    responseHeaders(headerWithName("Content-Type").description("The Content-Type of the payload, e.g. `application/hal+json`"))));
    }
}

我得到錯誤：

java.lang.AssertionError: Status expected:<200> but was:<404>

他向上述代碼發出GET請求的正確方法是什么？ 可能我需要在發回消息時添加響應 OK？

Answer 1

嗨，在我的情況下，我需要控制器的@MockBean 和所有自動裝配的服務；)

                .map(ResponseEntity::ok)
                .orElseGet(() -> notFound().build());

                    responseHeaders(headerWithName("Content-Type").description("The Content-Type of the payload, e.g. `application/hal+json`"))));
    }
}

我收到錯誤消息：

對上述代碼進行GET請求的正確方法是什么？ 消息發回時，可能需要添加響應OK嗎？
