spring - 测试 Spring 端点时如何防止 NestedServletException？

Question

我正在尝试 测试安全配置使用 @PreAuthorize(#oauth2.hasScope('scope') 保护的一些端点.当使用不具有所需范围的访问 token 通过 Postman 访问此类端点时，将返回以下 HTTP 状态代码 403(禁止):

{
    "error": "insufficient_scope",
    "error_description": "Insufficient scope for this resource",
    "scope": "scope"
}

这是我想要的预期行为。

在尝试测试此配置时，Springs NestedServletException在完成我的预期结果之前干扰了我的测试用例。

这是我要测试的 Controller 的简化版本:

@RestController
@RequestMapping(value = "/api")
public class OauthTestingResource {

    @PreAuthorize(#oauth2.hasScope('scope'))
    @RequestMapping(value = "/scope", method = RequestMethod.GET)
    public void endpoint() {
        // ...
    }
}

这是相应的测试用例:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = MyApplication.class)
@WebAppConfiguration
public class AuthorizationTest {

    @Autowired
    protected WebApplicationContext webApplicationContext;

    protected SecurityContext securityContext = Mockito.mock(SecurityContext.class);

    @Before
    public void setup() throws Exception {

        this.mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
        SecurityContextHolder.setContext(securityContext);
    }

    protected Authentication createMockAuth(Client client) {

        final List<GrantedAuthority> authorities = new ArrayList<>();
        authorities.add(new SimpleGrantedAuthority("ROLE_USER"));

        final Authentication pwAuth = new UsernamePasswordAuthenticationToken("testuser", "testpw", authorities);

        final TokenRequest request = new TokenRequest(new HashMap<>(), client.getClientId(), client.getScopes(), "password");

        final OAuthClient oauthClient = new OAuthClient(client, GrantType.PASSWORD);

        return new OAuth2Authentication(request.createOAuth2Request(oauthClient), pwAuth);
    }
    @Test
    public void testAppScope() throws Exception {

        final Client client = new Client("id1", "secret1");

        client.setScope("scope");
        Mockito.when(securityContext.getAuthentication()).thenReturn(createMockAuth(client));
        // this test passes
        mvc.perform(get("/api/scope")).andExpect(status().isOk()); 

        client.setScope("other_scope");
        Mockito.when(securityContext.getAuthentication()).thenReturn(createMockAuth(client));
        // NestedServletException thrown here
        mvc.perform(get("/api/scope")).andExpect(status().isForbidden()); 
    }
}

引发的异常如下(这是预期的):

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.security.access.AccessDeniedException: Insufficient scope for this resource

我的问题是如何防止此异常干扰我的测试用例？

Answer 1

我有一个类似的情况，并通过使用抑制了 NestedServletException@Test(expected = NestedServletException.class)然后我能够掌握 MvcResult 并对其进行进一步的断言，就像在其他测试中一样:

// then
MvcResult result = resultActions.andExpect(status().isServiceUnavailable()).andReturn();
String message = result.getResponse().getContentAsString();
assertThat(message).contains("ABC");
assertThat(result.getResolvedException().getClass()).isEqualTo(XYZ.class);

它似乎奏效了。
