无法在 Spring Reactive 中模拟我的服务方法
Cannot able to Mock my service's methods in Spring Reactive
我正在尝试使用 Spring 反应式开发聊天应用程序。基本上，我有一个 CommentRestController，它有 postComment 和列表方法。 - 我已经删除了 list 方法和其他一些不必要的和不相关的方法，因为我现在不关注它们 - 在这里；
@RestController
@RequiredArgsConstructor
@RequestMapping("/chat/comment")
public class CommentRestController {
private final CommentService commentService;
private final ChannelService channelService;
@PostMapping("/add")
public Mono<AddCommentResponse> postComment(@Valid @RequestBody Comment comment, ServerWebExchange serverWebExchange) {
String userName = serverWebExchange.getAttribute("username");
return commentService.save(userName, comment);
}
}
现在，我正在尝试编写此控制器的文档测试。我遇到的问题是，我无法模拟我的 commentService 的 save 方法。它实际上是在模拟实例而不是方法。
这是我的文档测试 class。
@RunWith(SpringRunner.class)
@SpringBootTest(properties = {"token-validation-service.url = http://localhost:8080/token-validation-service/", "profanity.similarity = 0.9"})
@AutoConfigureRestDocs(outputDir = "target/generated-snippets")
public class CommentRestControllerDocumentationTest {
@Rule
public final JUnitRestDocumentation restDocumentation = new JUnitRestDocumentation();
private WebTestClient webTestClient;
@Autowired
private CommentRestController commentRestController;
@MockBean
CommentService commentService;
@MockBean
ChannelService channelService;
@MockBean
ServerWebExchange serverWebExchange;
@MockBean
TokenValidationServiceClient tokenValidationServiceClient;
@MockBean
OperationResult operationResult;
@MockBean
AddCommentResponse addCommentResponse;
private RequestHeadersSnippet requestHeaderSnippet = requestHeaders(headerWithName("X-Auth-Token").description("Authentication Access Token"));
private FieldDescriptor responseReturnCode = fieldWithPath("meta.return_code").description("Operation return code");
private FieldDescriptor responseMessage = fieldWithPath("meta.message").description("Operation message");
private FieldDescriptor idField = fieldWithPath("id").description("id of the comment");
private FieldDescriptor authorField = fieldWithPath("author").description("Author of the comment");
private FieldDescriptor commentField = fieldWithPath("text").description("Comment itself");
private FieldDescriptor channelIdField = fieldWithPath("channelId").description("Channel Id of the comment");
private FieldDescriptor timestampField = fieldWithPath("timestamp").description("Timestamp of the comment");
private FieldDescriptor usernameField = fieldWithPath("username").description("Username of the comment, to check who commented");
private FieldDescriptor isBadField = fieldWithPath("isBad").description("Profanity check for comment");
@Before
public void setUp() {
webTestClient = WebTestClient.bindToController(commentRestController)
.configureClient()
.filter(documentationConfiguration(restDocumentation))
.build();
}
@Test
@WithMockUser
public void postComment() throws Exception {
String stubName = "postComment";
Comment comment = new Comment();
comment.setId("1");
comment.setAuthor("orcun");
comment.setChannelId("123");
comment.setText("This is a test method");
comment.setIsBad(false);
comment.setTimestamp("1479249799770");
comment.setUsername("5332109939");
operationResult.setReturnCode(ChatServiceConstants.SUCCESS_CODE);
operationResult.setMessage(ChatServiceConstants.SUCCESS_MESSAGE);
addCommentResponse.setOperationResult(operationResult);
when(serverWebExchange.getAttribute("username")).thenReturn("5332109939");
String userName = serverWebExchange.getAttribute("username");
when(commentService.save(userName, comment)).thenReturn(Mono.just(addCommentResponse));
webTestClient.post().uri("/chat/comment/add")
.header("X-Auth-Token", "8811-1113")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.body(BodyInserters.fromObject(comment))
.exchange()
.expectStatus().isOk()
.expectBody()
.consumeWith(document(stubName,
requestFields(idField, authorField, commentField, timestampField,
channelIdField, usernameField, isBadField),
responseFields(responseReturnCode, responseMessage)));
}
}
当我 运行 执行此操作时，我看到一个错误，指出响应正文为空。这是：

当我打开 target/generated-snippets 的路径时，我看到生成了该方法的文档，但响应- fields.adoc 为空。
我通过调试会话检查了代码，我意识到我无法 mock 我的 commentService.save()方法。
任何帮助将不胜感激。
提前致谢。
问题是响应式开发需要与时间无关的应用程序。这就是为什么像 twitter 或聊天这样的应用程序正在使用它。在大多数像我这样的情况下，预期的内容甚至无法回到它所属的位置。
这就是为什么为响应式项目编写单元测试比您想象的要难一些。
我上面的问题的答案仅此而已。希望对大家有所帮助。
