java - 无法加载ApplicationContext。无法创建集成测试

Question

我尝试为此 REST Controller 创建集成测试:

@RestController
@RequestMapping(path = {"/api/reports", "/api"})
public class DependencyReportController {

private final DependencyDifferenceService differenceService;

public DependencyReportController(DependencyDifferenceService differenceService) {
    this.differenceService = differenceService;
}

@GetMapping(path = {"/dependencies/difference", "/deps/diff"},
    produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public ServiceDependenciesReport get() {
    return differenceService.getAllDiffs();
}


}

我的测试，我尝试检查状态:

@RunWith(SpringRunner.class)
@WebMvcTest(DependencyReportController.class)
public class DependencyReportControllerApiTest {
@Autowired
private MockMvc mockMvc;

@MockBean
private DependencyDifferenceService differenceService;

@Test
public void test() throws Exception{
    ServiceDependenciesReport report = new ServiceDependenciesReport();
    report.setElapsed("elapsed");
    report.setSuccess(true);
    when(differenceService.getAllDiffs()).thenReturn(report);
    this.mockMvc.perform(get("/dependencies/difference")).andDo(print()).andExpect(status().isOk());
}



 }

而且它不起作用。完整的堆栈跟踪:

我从不编写集成测试，也不明白我做错了什么？这可能是什么问题？据我了解，我应该添加 @ComponentScan 或这样的东西？

Answer 1

如果你想编写集成测试，请使用SpringBootTest

@SpringBootTest annotation will load the fully ApplicationContext

同时

@WebMvcTest annotation will load only the controller layer of the application.
