我如何为登录控制器进行模拟测试

Question

我想为我的控制器创建一个弹簧启动测试，但我不知道如何。
这是我的代码：

控制器：

@PostMapping(value = Constants.LOGOUT_URL)
public String logout (HttpServletRequest request) throws ApiException {
    String authHeader = request.getHeader("Authorization");
    if (authHeader != null) {
        try {
            String tokenValue = authHeader.replace("Bearer", "").trim();
            OAuth2AccessToken accessToken = tokenStore.readAccessToken(tokenValue);
            tokenStore.removeAccessToken(accessToken);
        } catch (Exception e) {
            return HttpStatus.NOT_FOUND.toString();
        }
    }
    return Utils.convertDateTime();
}

这是我的测试，这给我带了一个NullPoInterException：

@RunWith(SpringJUnit4ClassRunner.class)
@AutoConfigureRestDocs
public class AuthControllerTest {
    @Rule
    public JUnitRestDocumentation jUnitRestDocumentation = new JUnitRestDocumentation();
    @InjectMocks
    private AuthController controller = new AuthController();
    // To be initialised in the setup method.
    private MockMvc mockMvc;
    @Mock
    private AuthService service;
    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.standaloneSetup(controller)
            .apply(documentationConfiguration(this.jUnitRestDocumentation))
            .build();
    }
    @Test
    public void getLogout() throws Exception, ApiException {
        String result = "{"date":"20190212:0000"}";
       HttpServletRequest request = Mockito.mock(HttpServletRequest.class);
       when(request.getHeader("principal")).thenReturn("admin");
       when(request.getHeader("authorization")).thenReturn("authtoken");
       when(controller.logout(any(request.getClass()))).thenReturn(result);
    }
}

我不知道如何进行注销控制器的测试

我得到的例外是：

java.lang.NullPointerException: null
    at com.sodexo.oneapp.api.auth.AuthController.login(AuthController.java:35)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
    at java.lang.reflect.Method.invoke(Method.java:498)

您可以放心地使用REST来测试控制器非常容易。这是文档：https：//github.com/rest-assure/rest-ashure/wiki/usage

测试看起来像这样：

@RunWith(MockitoJUnitRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
class MyControllerTest {
@Mock
private MyService myService;
@InjectMocks
private MyController MyController;
@Before
public static void init(){
    RestAssured.baseURI = "http://localhost";
    RestAssured.port = 8080;
}
@Test
void givenUrl_whenSuccessOnGetLogoutAndStuff_thenCorrect() {
    when(this.myService.getLogout(stuff)).thenReturn(something);
    given()
        .standaloneSetup(new MyController(this.myService))
        .header("principal", "admin")
        .header("authorization", "authtoken")
    .when()
        .get("/logout")
    .then()
        .statusCode(200)
        .statusLine("...")
        .body(something);
    }
}

请确保使用保证的MockMVC模块：

import static io.restassured.module.mockmvc.RestAssuredMockMvc.*;
