Description
I'm using Jest to do unit test based on Jasmine 2
When I was testing my async action store having Parse query
It throws this error :
''Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVL."
Here is my code from _tests/actions/auth-test.js
it('should creates SIGNUP_REQUEST and SIGNUP_SUCCESS when signup has been done successfully', (done) => {
/* If this account has already exists in Parse database, it will get SIGNUP_ERROR */
const expectedActions = [
{ type: 'SIGNUP_REQUEST', payload: { username, password } },
{ type: 'SIGNUP_SUCCESS', payload: { user: { /* whatever. Anyway, it needs to be defined */ } } },
];
const store = mockStore({}, expectedActions, done);
store.dispatch(Auth.signup(username, password));
})
Finally, I revised some code from yours and tested successfully.
It seems that the main problem is Jasmine done() doesn't be invoked, so it causes this error.
Here is my revised code :
function configureMockStore(middlewares = []) {
return function mockStore(getState, expectedActions, done) {
if (!Array.isArray(expectedActions)) {
throw new Error('expectedActions should be an array of expected actions.');
}
if (typeof done !== 'undefined' && typeof done !== 'function') {
throw new Error('done should either be undefined or function.');
}
function mockStoreWithoutMiddleware() {
return {
getState() {
return typeof getState === 'function' ? getState() : getState;
},
dispatch(action) {
const expectedAction = expectedActions.shift();
/* Customize for auth action test */
switch(action.type) {
case 'SIGNUP_REQUEST':
case 'LOGIN_REQUEST':
expect(action).toEqual(expectedAction);
break;
case 'SIGNUP_SUCCESS':
case 'LOGIN_SUCCESS':
expect(action.type).toEqual(expectedAction.type);
expect(action.payload.user).toBeDefined();
break;
case 'SIGNUP_ERROR':
case 'LOGIN_ERROR':
expect(action.type).toEqual(expectedAction.type);
expect(action.payload.error).toBeDefined();
break;
}
if (done && !expectedActions.length) {
done();
}
return action;
}
}
}
const mockStoreWithMiddleware = applyMiddleware(
...middlewares
)(mockStoreWithoutMiddleware);
return mockStoreWithMiddleware();
}
}
