Я работаю над двумя почти идентичными тестовыми случаями, где я должен утверждать, что два эффекта NgRx возвращают поток логических значений.В первом тестовом примере все работает, как и ожидалось, и, хотя для второго тестового примера то же самое, я не могу заставить его работать так, как ожидалось.Что бы я ни делал, полученное значение всегда является пустым массивом:
expect(received).toEqual(expected) // deep equality
- Expected
+ Received
- Array [
- Object {
- "frame": 10,
- "notification": Notification {
- "error": undefined,
- "hasValue": true,
- "kind": "N",
- "value": true,
- },
- },
- ]
+ Array []
Рабочий тест
logger.effects.spec.ts:
describe('LoggerEffects', () => {
let actions$: Observable<ApiFailure>;
let effects: LoggerEffects;
const serviceMock = <AppLoggerServiceI>{ failure: ({ body, title }) => of(true) };
beforeEach(() => {
TestBed.configureTestingModule({
imports: [StoreModule.forRoot({})],
providers: [
LoggerEffects,
provideMockActions(() => actions$),
{
provide: 'appLoggerService',
useValue: serviceMock
}
]
});
effects = TestBed.get(LoggerEffects);
});
const failure = new HttpErrorResponse({ error: 'HttpErrorResponse' });
describe('logApiFailure$', () => {
it('should return a stream of boolean if the dispatched action is ApiActions.searchFailure', () => {
const action = ApiActions.searchFailure({ failure });
actions$ = hot('-a--', { a: action });
const expected = cold('-b--', { b: true });
expect(effects.logApiFailure$).toBeObservable(expected);
});
});
});
logger.effects.ts:
logApiFailure$ = createEffect(
() =>
this.actions$.pipe(
ofType(ApiActions.searchFailure),
exhaustMap(({ failure: { body, title } }) =>
this.appLoggerService.failure({
body,
title
})
)
),
{ dispatch: false }
);
Неудачный тест
router.effects.spec.ts:
describe('RouterEffects', () => {
let actions$: Observable<boolean>;
let effects: RouterEffects;
const routerMock = <Partial<Router>>{ navigate: (commands: any[]) => Promise.resolve(true) };
let router: Router;
beforeEach(() => {
TestBed.configureTestingModule({
imports: [StoreModule.forRoot({})],
providers: [
RouterEffects,
provideMockActions(() => actions$),
{
provide: Router,
useValue: routerMock
}
]
});
effects = TestBed.get(RouterEffects);
});
describe('navigateTo$', () => {
it('should return a stream of boolean if the dispatched action is RouterActions.navigateTo', () => {
const action = RouterActions.navigateTo();
actions$ = hot('-a--', { a: action });
const expected = cold('-b--', { b: true });
console.log('toto', effects.navigateTo$);
expect(effects.navigateTo$).toBeObservable(expected);
});
});
});
router.effects.ts:
navigateTo$ = createEffect(
() =>
this.actions$.pipe(
ofType(RouterActions.navigateTo),
exhaustMap(() => this.router.navigate(['my-route', {}]))
),
{ dispatch: false }
);
На данный момент, я предполагаю, что что-то не так с Hot Observable в router.effects.spec.ts, которыйпредотвращает эффект отправки действия navigateTo.Есть ли у вас мысли по этому поводу?
