[英]Spring Boot MockMVC returning empty body with statuscode 200 when unit testing
[英]Spring MockMvc is returning 200 instead of a 201. How to debug?
我正在嘗試使用 Spring MockMvc 測試具有多個 HTTP 動詞的控制器。 目前GET
和DELETE
按預期工作,但PUT
和PATCH
沒有返回 201,而它們應該返回。
PATCH
控制器設置如下:
@CustomRequestMapping(method = PATCH, value = "/{api-root}")
public ResponseEntity patch(@PathVariable(value = "api-root") String id, @RequestBody ApiRoot apiRoot) {
return apiRootService.softUpdate(id, apiRoot);
}
@CustomRequestMapping...
注釋只是將consumes
和produces
設置為特定的內容類型。
softUpdate()
方法執行以下操作:
public ResponseEntity softUpdate(String id, ApiRoot apiRoot) {
if (apiRoot.getId() == null) {
apiRoot.setId(id);
}
ApiRootDocument updated = softUpdate(apiRoot);
return ResponseEntity
.created(EscapeUtil.buildUrl(applicationProperties.getHostname(), applicationProperties.getPort(), id))
.body(updated);
}
這是在 MockMvc 單元測試之外工作和測試的。 它正確地將201 Created
返回給 Postman,主體是作為PATCH
結果創建的新 JSON 對象。
我的測試設置為:
public void testPatchApiRootEndpoint() throws Exception {
String testTitle = "New Test Title";
// Mock the service call for softUpdate() to return 'created' in the same way that the method does
when(apiRootService.softUpdate(TestData.apiRoot1.getId(), TestData.apiRoot1.withTitle(testTitle)))
.thenReturn(ResponseEntity
.created(URI.create(EscapeUtil.buildUrlString("localhost", "8001", TestData.apiRoot1.getId())))
.body((ApiRootDocument) TestData.apiRoot1.withTitle(testTitle)));
// Perform a patch update using a new title provided as key-value
JsonObject titleJson = new JsonObject();
titleJson.addProperty("title", testTitle);
mockMvc.perform(patch("/{api-root}", TestData.apiRoot1.getId())
.contentType(Constants.TAXII2_CONTENT_TYPE)
.content(titleJson.toString()))
.andExpect(status().isCreated());
}
這導致200
被返回,而不是201
。 我真的很困惑,一直很難研究。 大多數類似的問題是在他們期望 2XX 時找到 4XX 響應代碼,解決方案通常與請求的設置有關。
我似乎能找到的唯一有趣的日志是:
09:48:25.064 [main] DEBUG org.springframework.test.web.servlet.TestDispatcherServlet - Servlet '' configured successfully
09:48:25.208 [main] DEBUG org.springframework.test.web.servlet.TestDispatcherServlet - DispatcherServlet with name '' processing PATCH request for [/api-root-1]

看起來您的模擬電話無效。 您可以輕松檢查是否將值替換為 any():
when(apiRootService.softUpdate(Mockito.any(), Mockito.any())
.thenReturn(ResponseEntity
.created(URI.create(EscapeUtil.buildUrlString("localhost", "8001", TestData.apiRoot1.getId())))
.body((ApiRootDocument) TestData.apiRoot1.withTitle(testTitle)));
我剛剛檢查了您是否使用了錯誤的控制器模擬返回 200 狀態,但如果模擬正確,我得到 201。
