How to test a race

[hdsenevi]

Hi, first of all thank you for taking the time to create and release this package. Saved a lot of time for me.

Question
How to test a race in redux-saga

Saga code

// Render a simple custom alert view with OK and CANCEL buttons
yield put(SettingsActions.alertView.showAlertView());

// Wait for user to interact with one of the buttons before saga continues
const { alertAction } = yield race({
    alertAction: take(SettingsActionTypes.alertView.ON_ACTION_TRIGGERED),
});

// User interacted with either OK or CANCEL so take appropriate action (save relevant prefs)
switch (alertAction.payload) {
    case SettingsFieldTypes.alertView.type.CONFIRM:
        yield put(RealmActions.saveUser(**with OK setting**));
        break;
    default:
        yield put(RealmActions.saveUser(**with CANCEL setting**));
        break;
}

Saga test

// Test if an alert is getting trigger
it('should call an AlertView', (result) => {
    expect(result).toEqual(put(SettingsActions.alertView.showAlertView()));
});

// Test if a race is getting called?
it('should wait for AlertView action triggered', (result) => {
    expect(result).toEqual(race({
        alertAction: take(SettingsActionTypes.alertView.ON_ACTION_TRIGGERED),
    }));
});

// Up to here it's fine, but after this point how do I test the saga?
// In actuality, we wait for user to tap on OK, or CANCEL before continuing with the saga
// But how do I simulate that

Sorry, partly answering my own question. After posting the question I realised that I could do the following

it('should call an AlertView', (result) => {
    expect(result).toEqual(put(SettingsActions.alertView.showAlertView()));
});

it('should wait for AlertView action triggered', (result) => {
    const alertAction = race({
        alertAction: take(SettingsActionTypes.alertView.ON_ACTION_TRIGGERED),
    });
    expect(result).toEqual(alertAction);
    return ({ alertAction });
});

it('should save user preferences', (result) => {
    expect(result).toEqual(put(RealmActions.saveUser()));
});

Now the problem is, I'm only testing the default case of the switch statement.
