unit testing - HowTo test Modal emitter in Angular2? -

-

this class component:

export class goalsettingspage {      public goal: goal;       dismiss() {         this.viewctrl.dismiss();     } }

this test:

  it('should emit on click', () => {          let g = new goal()         let settingmodal = modal.create(goalsettingspage, { g:goal });          settingmodal.subscribe(hc => {             console.log(hc);             expect(hc).toequal({hascompleted:true});         });          settingmodal.dismiss()     })

this error:

04 07 2016 16:36:48.438:error [chrome 51.0.2704 (mac os x 10.11.3) | goal settings | should emit on click]: typeerror: cannot read property 'remove' of undefined     @ modal.viewcontroller.dismiss (http://localhost:9876/absolute/var/folders/zb/tpysrhsx7hbg1dnsn4gwtqq00000gn/t/65a6294f711f882f7429da26bc12e438.browserify?2c82fe582a9911b998cb77bce54ea6804460d5cd:59060:25)
