first is not a function while writing Jasmine test cases using angular 2-4
I am facing error while writing test cases with jasmine
I am writing test case for below code
@select([
'reportingTabState',
'actualDelayDetails',
'ActualDelayDetailsResponse',
'DelayDetails',
'actualDelayDetails',
])
actualDelayDetails$;
this.actualDelayDetailsSub = this.actualDelayDetails$
.first()
.subscribe(actualDelayDetails => {
//rest of the code..
});
Mocking it in my spec.ts like this
const actualDelay$ = MockNgRedux.getSelectorStub([
'ActualDelayDetailsResponse',
]);
actualDelay$.next(actualDelayDetails);
actualDelay$.complete();
Object.defineProperty(component, 'actualDelayDetails$', { writable: true });
component.actualDelayDetails$ = actualDelay$;
fixture.detectChanges();
In actualDelayDetails I am having mock object like this:
const actualDelayDetails = {
ActualDelayDetailsResponse: [{
primaryDelay: {
code: 'CR2F',
minutes: '1 min',
details: 'REPLACEMENT OF A FLIGHT OPS CREWMEMBER D',
detailsDesc: 'REPLACEMENT OF A FLIGHT OPS CREWMEMBER D',
},
secondaryDelay: {
code: 'F06',
minutes: '23 min',
details: 'DUE TO CAPTAIN DISCRETION TO NOT ACCEPT',
detailsDesc: 'DUE TO CAPTAIN DISCRETION TO NOT ACCEPT',
},
}],
};
Please help me out with this.

You probably have a import 'rxjs/add/operator/first' (or something similar) inside your main.ts. This will patch the observable used inside your application to include this operator for chaining. You can solve this by including it on top of your test script, or in a global script which is loaded by your test environment.
Even better would be to move to the new way of chaining operators by using pipe():
import { first } from 'rxjs/operators';
this.actualDelayDetails$.pipe(
first()
).subscribe(() => {
This way you can be sure that what's used in your file, is also available in your tests

"The first() operator takes an optional predicate function and emits an error notification when no value matched when the source completed."
So I tried removing first() method and it worked fine without breaking my functionality.
Thanks PierreDuc for instant reply. but unfortunately this solution was not working for me.
