ReferenceError: spyOnProperty is not defined

Question

it('should update treatment instruction data in UI', async(() => {
     const spy = spyOnProperty(appService.treatmentInstruction, 'next', 
     'get').and.returnValue(treatmentInst);

    component.updateTemplateInUI();
    fixture.whenStable().then(() => {
        expect(component.structuresInfo.length).toBe(2);
        expect(component.oarStructureLength).toBe(4);
        expect(component.notesArray.length).toBe(2);
    });
}));

ReferenceError: spyOnProperty is not defined error is coming on running test case.

I want to spyOn treatmentInstruction BehaviorSubjectthat is present in my service as mentioned below :

treatmentInstruction = new BehaviorSubject(this.myGlobalVar);
currentTreatmentInstruction = this.treatmentInstruction.asObservable();

spyOn is for installing spy on function. I want to spyOn on service property of type Observable. — Nilesh Gupta, Jan 11 '19 at 06:58
Thanks Rakesh Makluri. It worked on upgrading jasmine core version — Nilesh Gupta, Jan 11 '19 at 07:33
can u please help me with access type of BehaviorSubject as it is giving 'Failed: Property next does not have access type get' error — Nilesh Gupta, Jan 11 '19 at 07:35
Are you trying to put a new value into the BehaviorSubject for testing purposes? If so, simply call `appService.treatmentInstruction.next(treatmentInst)` rather than trying to spy on it... — dmcgrandle, Jan 11 '19 at 16:59
Yeah that we can do ... But in unit testing we avoid calling another file function, so wanted to spyOn... please help me with that. — Nilesh Gupta, Jan 13 '19 at 05:58
can we run ng test command when we don't have database connection ? so far i was doing unit test cases with my API and database connection on, while testing i felt during test case execution event after spy my actual database data is coming (found this while debugging). Please correct me whether im doing it right or wrong. — Nilesh Gupta, Jan 22 '19 at 13:34

spyOnProperty was added on jasmine 2.6.0, be sure that you fulfill that requisite.

Since jasmine is a dependency of karma-jasmine update that instead. Looks like on old version of this library jasmine was added as a peer dependency so it would be up to you to install the correct version of jasmine.

I had this issue, updating jasmine version didn't help. The problem came for jshint, in your test directory you must modify your .jshuntrc file : in "globals": { add => "spyOnProperty" : false

Worked for me
