I'm trying to mock this axios call:
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});
})
}
}
Which on a successful call, should dispatch both action creators fetchCountryPending() and fetchCountryFullfilled(country). When I mock it like so:
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))
});
});
The second expect fails and console.log(actions) only shows an array with the one action, but it should contain both actions, fetchCountryPending and fetchCountrySuccess. When I log ('dispatched'), it shows the second action is getting dispatched in the terminal.
I couldn't get a then(() => {}) block to work but I was able to await the function and make it async:
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))
});
});
