The issue lies within the SuperUserComponent. The spec file you shared pertains to the DashboardService.
Regardless, it is recommended to create a mock service for DashboardService and utilize it with useClass.
Allow me to assist you in modifying the super-user.component.spec.ts:
class export MockDashboardService{
userslastlogin(){
return of({
// Response from http call as per actual service
})
}
}
describe('SuperuserComponent', () => {
let component: SuperuserComponent;
let fixture: ComponentFixture<SuperuserComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [SuperuserComponent],
imports: [ ... required imports],
providers: [
{ provide: DashboardService, useClass: MockDashboardService},
// Replace other services accordingly
]
}).compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(SuperuserComponent);
component = fixture.componentInstance;
})
});
