测试弹簧休息异步控制器时出错

Question

控制器

    @PostMapping("/endpoint/group/move")
    public DeferredResult<ResponseEntity<List<Endpoint>>> moveEndpointGroup(@RequestBody List<String> EndpointIds,
            @RequestParam("from") String fromGroupId, @RequestParam("to") String toGroupId)
            throws ResourceNotFoundException, ExecutionException {
        DeferredResult<ResponseEntity<List<Endpoint>>> result = new DeferredResult<>();
        if (EndpointIds != null && !EndpointIds.isEmpty()) {
            CompletableFuture.supplyAsync(() -> EndpointService.moveEndpoints(EndpointIds, fromGroupId, toGroupId), executor)
                    .whenComplete((movedEndpointsList, ex) -> {
                        if (ex != null) {
                            throw new RuntimeException(ex);
                        }
                        if (movedEndpointsList.size() == EndpointIds.size()) {
                            result.setResult(ResponseEntity.status(HttpStatus.OK).body(movedEndpointsList));
                        } else {
                            result.setResult(ResponseEntity.status(HttpStatus.PARTIAL_CONTENT).body(movedEndpointsList));
                        }
                    });
        }
        return result;
    }

我已经编写了以下测试方法，它不起作用。 当我运行此测试时，在指定的 timeToWait 期间未设置处理程序的异步结果。

有人可以帮助我哪里做错了吗？

    @Test
    public void testMoveEndpointGroup_WhenSuccess() throws Exception {

        List<Endpoint> EndpointList = Arrays.asList(Endpoint, Endpoint);

        List<String> EndpointIds = Arrays.asList("123");

        Mockito.when(EndpointService.moveEndpoints(Mockito.any(), Mockito.anyString(), Mockito.anyString()))
                .thenReturn(EndpointList);

        RequestBuilder requestBuilder = MockMvcRequestBuilders.post("/endpoint/group/move")
                .contentType(MediaType.APPLICATION_JSON)
                .content(objectMapper.writeValueAsString(EndpointIds)).param("from", "gorupA").param("to", "groupB");

        MvcResult result = mvc.perform(requestBuilder).andReturn();

        result = mvc.perform(MockMvcRequestBuilders.asyncDispatch(result)).andDo(MockMvcResultHandlers.print()).andReturn();


        JsonNode actual = objectMapper.readTree(result.getResponse().getContentAsString()).get("content");

        String expected = objectMapper.writeValueAsString(Arrays.asList(EndpointList));

        Assert.assertEquals(expected, actual.toString());

    }

Answer 1

1）你有带网址的控制器

@PostMapping("/endpoint/group/move")

但是在测试中，您将请求发送到“/Endpoint s /group/move”（额外的）

post("/Endpoints/group/move")

2) 而且你不需要 '.get("content")' 因为你已经解析了响应体。 看起来您也不需要解析 JsonNode 的答案，只需使用 String

String actual = result.getResponse().getContentAsString();
String expected = objectMapper.writeValueAsString(Arrays.asList(EndpointList));
Assert.assertEquals(expected, actual.toString());
