我想为 Rest api 创建 JUnit 测试并生成 api 文档。我想测试这段代码:
休息 Controller
@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());
}
}
存储库界面
public interface PaymentTransactionRepository extends CrudRepository<PaymentTransactions, Integer>, JpaSpecificationExecutor<PaymentTransactions> {
Optional<PaymentTransactions> findById(Integer id);
}
我尝试用 mockito 实现这个 JUnit5 测试:
@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`"))));
}
}
我得到错误:
java.lang.AssertionError: Status expected:<200> but was:<404>
向上述代码发出 GET 请求的正确方法是什么? 可能我需要在发回消息时添加响应 OK?
最佳答案
嗨,在我的例子中,我需要 Controller 的 @MockBean 和所有 Autowiring 的服务;)
关于java.lang.AssertionError : Status expected:<200> but was:<404> in Junit test 错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/53904887/
