我正试图模仿这个axios电话:
export const fetchCountry = (query) => {
return dispatch => {
dispatch(fetchCountryPending());
return axios.get(`${process.env.REACT_APP_API_URL}/api/v1/countries/?search=${query}`)
.then(response => {
const country = response.data;
dispatch(fetchCountryFulfilled(country));
})
.catch(err => {
dispatch(fetchCountryRejected());
dispatch({type: "ADD_ERROR", error: err});
})
}
}
在成功通话中,应该同时发送动作创建者fetchCountryPending()和fetchCountryFullfilled(country) . 当我嘲笑它时:
const middlewares = [thunk];
const mockStore = configureMockStore(middlewares);
// Async action tests
describe('country async actions', () => {
let store;
let mock;
beforeEach(function () {
mock = new MockAdapter(axios)
store = mockStore({ country: [], fetching: false, fetched: true })
});
afterEach(function () {
mock.restore();
store.clearActions();
});
it('dispatches FETCH_COUNTRY_FULFILLED after axios request', () => {
const query = 'Aland Islands'
mock.onGet(`${process.env.REACT_APP_API_URL}/api/v1/countries/?search=${query}`).replyOnce(200, country)
store.dispatch(countryActions.fetchCountry(query))
const actions = store.getActions()
console.log(actions)
expect(actions[0]).toEqual(countryActions.fetchCountryPending())
expect(actions[1]).toEqual(countryActions.fetchCountryFulfilled(country))
});
});
第二个期望失败,console.log(actions)仅显示具有一个操作的数组,但它应包含两个操作fetchCountryPending和fetchCountrySuccess . 当我记录('dispatched')时,它显示第二个动作正在终端中调度 .

你可以尝试让它阻止异步并发送动作 . 我相信测试在你的get请求返回值之前运行
