Почему не работает эта шпионская работа? Я создаю экземпляр prescriptionService и слежу за методом fetchClientPrescriptions
, но когда я проверяю, был ли он вызван, я получаю сообщение об ошибке. И все же первый шпион для getClientPrescriptions
работает просто отлично.
Тест:
let prescriptions = [
{"ndcpackage": "58160082552", "form": "1.0ML Syringe", "name": "Havrix", "dosage": "Havrix INJ 720UNIT", "quantity": "3", "refill_freq": 30},
{"ndcpackage": "59310058020", "form": "1.0EA Box", "name": "Proair Respiclick", "dosage": "Proair Respiclick AER", "quantity": "0", "refill_freq": 30}
];
it('should fetch client prescriptions if clientId is provided', async(() => {
let spyC = spyOn(component, 'getClientPrescriptions');
let spyS = spyOn(prescriptionService, 'fetchClientPrescriptions').and.returnValue(of(prescriptions));
component.clientId = 5;
component.ngOnInit();
fixture.whenStable().then(() => {
expect(spyC).toHaveBeenCalled();
expect(spyS).toHaveBeenCalled();
expect(component.currentPrescriptions).toEqual(prescriptions);
});
}));
Сервис:
fetchClientPrescriptions(id: any) {
return this.http.get<DrugSelection[]>(environment.apiURL + '/fetch-client-rx/' + id);
}
Компонент:
ngOnInit() {
if (this.clientId != null) {
this.getClientPrescriptions();
}
}
getClientPrescriptions() {
this.prescriptionService.fetchClientPrescriptions(this.clientId).subscribe(p => {
this.dataSource = new MatTableDataSource<DrugSelection>(p);
this.dataSource.sort = this.sort;
this.currentPrescriptions = p;
});
}
Ошибки:
Error: Expected spy fetchClientPrescriptions to have been called.
