Question

我使用Spring Initializer（https://start.spring.io/）生成了新项目 Spring boot - 2.0.0.RC1，版本5.0.3.RELEASE。

添加了以下控制器：

@RestController
@ResponseBody
@RequestMapping(value = "/customer")
public class CustomerController {
    @GetMapping("/")
    public Future<ResponseEntity<String>> get1() {
        return CompletableFuture.supplyAsync(() -> new ResponseEntity<String ("not found", HttpStatus.NOT_FOUND));
    }
}

并在build.gradle中具有以下依赖项部分（问题也可以在maven构建中复制）

dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework:spring-web')
    testCompile('org.springframework:spring-test')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

以下测试失败：

@SpringBootTest
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
public class CustomerControllerTest {
    @Autowired
    private MockMvc mockMvc;

    @Test
    public void test404() throws Exception {
        MvcResult asyncResult = mockMvc.perform(MockMvcRequestBuilders.get("/customer/"))
                .andExpect(request().asyncStarted())
                .andReturn();

        mockMvc.perform(asyncDispatch(asyncResult))
                .andExpect(status().isNotFound());
    }
}

使用以下日志：

    Forwarded URL = null

java.lang.AssertionError: Status 
Expected :404
Actual   :200

似乎测试将状态代码视为200而不是404.但是正文内容会正确返回。有意义的是降级到5.0.0.RELEASE的春季测试 - 解决了这个问题：

testCompile('org.springframework:spring-test:5.0.0.RELEASE')

这是一个弹簧测试错误吗？

Answer 1

看起来确实像春虫：https://jira.spring.io/browse/SPR-16430 移至5.0.4.BUILD-SNAPSHOT解决了问题

无法在spring-test 5.0.3中的MockMvc异步REST服务上测试HTTP状态（在5.0.0中有效）
