当调度多个操作时，Redux模拟存储只返回一个操作

Question

我正试图模拟这个axios调用：

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});
})
}
}

在成功调用时，应该同时调度操作创建者fetchCountryPending((和fetchCountryFullfilled(country(。当我这样嘲笑它时：

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))
});
});

第二个预期失败，console.log(actions(只显示一个有一个操作的数组，但它应该同时包含fetchCountryPending和fetchCountrySuccess这两个操作。当我登录("dispatched"(时，它显示第二个操作正在终端中调度。

Answer 1

你能试着让it块异步并调度操作吗。我相信测试在你的get请求返回值之前就已经运行了

Answer 2

我无法让then(((=>｛｝(块工作，但我可以等待函数并使其异步：

it('dispatches FETCH_COUNTRY_FULFILLED after axios request', async () => {
const query = 'Aland Islands'
mock.onGet(`${process.env.REACT_APP_API_URL}/api/v1/countries/?search=${query}`).replyOnce(200, country)
await 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))
});
});
