I want to check with unit tests angular if '

const Dialog

' modal window ist appier. I have to simulate get data from Database. I try to create a new Subject() and call it but every single time I get an empty object, what I do wrong.
I have this code .ts:

  onOpenEvent(event: CalendarEvent) {

if (event.title !== CalendarTypeConverterUtils.PRIVATE && Terminart.getArt(event.meta) === Terminart.ZTV) {

  this.openTerminDetailModal(event.meta);

   }



    if (Terminart.getArt(event.meta) === Terminart.BANKSPRECHZEIT) {

  const anfangDatum = new Date(event.meta.anfang);

  this.newTermin(anfangDatum);

   }

   }



    private openTerminDetailModal(termin: Termin) {

const terminDetailDialog = this.modalService.open(TerminAnzeigeComponent, { centered: true });

terminDetailDialog.componentInstance.termin = termin;

 }



   openNeuTerminModel(termin: Termin) {

const terminErstellDialog = this.modalService.open(TerminFormularComponent, { size: 'lg', centered: true });



    if (termin.anfang && termin.ende) {

     terminErstellDialog.componentInstance.updateForm(termin);

   }



    terminErstellDialog.result.then((result) => {

     this.updateCalendarEvents();

     if (this.paramService.hatBereitsTerminErstellt) {





const Dialog =this.modalService.open(TerminBestaetigungComponent, { size: 'lg', centered: true });

    terminBestaetDialog.componentInstance.result = result;

      }

    });

  }

And my Unit Test:

    it('should show popup if termin is create', () => {

      const myTrigger = new Subject();

       const modal = {

        componentInstance: {

        termin: {} as Termin,

         updateForm(newTermin: Termin) {

          this.termin = newTermin;

        }

       },

      result: myTrigger.toPromise()

    };

  myTrigger.next({

    id: 'test1',

    betreff: 'betreff von test1',

    herkunft: 'definitely not ztv',

    anfang: new Date(2017, 0, 1, 10, 42).getTime()

  });



     const testCalendarEvent: CalendarEvent<Termin> = {

    start: new Date(Number(myTrigger.asObservable.arguments.anfang)),

    title: 'definitely not private',

    meta: myTrigger.asObservable.arguments

  };



  component.onOpenEvent(testCalendarEvent);



  (component as any).paramService.hatBereitsTerminErstellt = true;



const TerminBestaetigungComponent= spyOn((component as any).modalService, 'open').and.returnValue(modal);



  expect(TerminBestaetigungComponent.calls.count()).toBe(1);

});

And I get some strange message: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them
