React redux 异步动作创建者测试

Question

我是 react redux 的新手。我正在尝试测试异步操作

动作看起来像 >

export function fetchUserJd() {
  return (dispatch) => {
    let url = FETCH_JD_ROOT_URL + page + "&" + size;
    dispatch({
      type: REQUEST_INITIATED
    })
    get(url)
      .then((response) => {
        if (response.status === 200) {
          dispatch({
            type: REQUEST_SUCCESSED,
          });
          dispatch({
            type: FETCHING_JOBDESCRIPTION_SUCCESS,
            data: response.payload,
          }
          )
        }
        else {
          dispatch({
            type: REQUEST_SUCCESSED
          })
          toastr.error("Error while fetching Job Description, Please check again");
          if (response.status === "") {
            toastr.error('Our server is down. Please check again');
          }
          dispatch({
            type: FETCHING_JOBDESCRIPTION_FAILED,
            data: response.status,
          });
          if (response.status === 401) {
            toastr.error('Please Login Again');
            localStorage.clear();
            history.push('/');
          }
        }
      })
  }

现在我正在尝试像这样测试它，

describe('Header component actions', () => {

    beforeEach(() => moxios.install());
     afterEach(() => moxios.uninstall());

    it('creates Fetch Jopb description when login action is successful', async (done) => {
        let url = FETCH_JD_ROOT_URL + page + "&" + size;
    moxios.stubRequest(url, {
      status: 201,
      response: mockData.jobDescriptionResponse
    });
    const expectedActions = [{ type: "FETCHING_JOBDESCRIPTION_SUCCESS"}];
    const store = mockStore({});
    await store.dispatch(fetchUserJd())
      .then(() => {
        expect(store.getActions()).toEqual(expectedActions);
      });
    done();
  });
});

所以我在这里遇到一个错误，

超时 - 在指定的超时时间内未调用异步回调 jasmine.DEFAULT_TIMEOUT_INTERVAL。

所以，我没有收到此错误，有人可以帮助我吗？ 而且我写测试用例的方式对吗？

要请求我也使用令牌，

headers: {
                "Authorization": localStorage.getItem("access_token") !== null ? `Bearer ` + localStorage.getItem("access_token") : null,
                "Content-Type": "application/json"
            }

我的呼叫服务是这样的，

export const get = (url) =>
    axios.get(
        url,
        {
            headers: {
                "Authorization": localStorage.getItem("access_token") !== null ? `Bearer ` + localStorage.getItem("access_token") : null,
                "Content-Type": "application/json"
            }
        }
    ).then(data => {
        if (data.status === HttpStatus.OK) {
            return {
                status: data.status,
                payload: data.data
            };
        }
    }).catch(err => {
        return {
            status: err.response.data,
            payload: null
        };
    });

那么，是不是因为我没有传递令牌？

您忘记从动作创建者返回Promise：您必须返回get 调用，它应该可以工作：

export function fetchUserJd() {
  return (dispatch) => {
    let url = FETCH_JD_ROOT_URL + page + "&" + size;
    dispatch({
      type: REQUEST_INITIATED
    })
    return get(url) // you missed the return statement here
      .then((response) => {
        if (response.status === 200) {
          dispatch({
            type: REQUEST_SUCCESSED,
          });
          dispatch({
            type: FETCHING_JOBDESCRIPTION_SUCCESS,
            data: response.payload,
          }
          )
        }
        else {
          dispatch({
            type: REQUEST_SUCCESSED
          })
          toastr.error("Error while fetching Job Description, Please check again");
          if (response.status === "") {
            toastr.error('Our server is down. Please check again');
          }
          dispatch({
            type: FETCHING_JOBDESCRIPTION_FAILED,
            data: response.status,
          });
          if (response.status === 401) {
            toastr.error('Please Login Again');
            localStorage.clear();
            history.push('/');
          }
        }
      })
  }
