I get "source is deprecated: This is an internal implementation detail, do not use." when I run the command npm lint on my code below:
set stream(source: Observable<any>) {
this.source = source;
}
If I take it out, it satisfies the lint, but it breaks my unit tests. Why is this?
If you are testing effects, you need to update the approach. I have changed using the provideMockActions, the action would be an let actions$: Observable;
fdescribe('PizzaEffects', () => { let actions$: Observable;; let service: Service; let effects: PizzaEffects; const data = givenPizzaData();
beforeEach(() => {
TestBed.configureTestingModule({
imports: [ApolloTestingModule],
providers: [
Service,
PizzaEffects,
Apollo,
// { provide: Actions, useFactory: getActions }, remove
provideMockActions(() => actions$),
]
});
actions$ = TestBed.get(Actions);
service = TestBed.get(Service);
effects = TestBed.get(PizzaEffects);
spyOn(service, 'loadData').and.returnValue(of(data));
});
describe('loadPizza', () => {
it('should return a collection from LoadPizzaSuccess', () => {
const action = new TriggerAction();
const completion = new LoadPizzaSuccess(data);
actions$ = hot('-a', { a: action });
const expected = cold('-b', { b: completion });
expect(effects.getPizzaEffect$).toBeObservable(expected);
});
});
});
