Angular 2 Testing PrimeNG ConfirmationDialog

Question

I'm writing jasmine unit test for following code:

this.confirmationService.confirm({
  message: 'Are you sure that you want to delete?',
  accept: () => {
   //some code to test
  }
});

How I can fake clicking of Yes in the dialog, to test code inside accept() function?

there's nothing that says you can't use JQuery to force the click event. — Brandon Miller, Dec 07 '17 at 13:56

In your template:

<p-confirmDialog #confirmDialog header="Confirmation" icon="fa fa-question-circle" width="425"></p-confirmDialog>

In your component:

@ViewChild('confirmDialog') confirmDialog: ConfirmDialog;

then you're able to invoke confirmDialog.accept().

You shouldn't add additional component properties only for test. To test it properly you should mock confirm function and call fake accept function inside to simulate correct behavior – Nickon Sep 15 '19 at 22:35

You can create spy like this:

spyOn(confirmationService, 'confirm').and.callFake((params: Confirmation) => {
    params.accept();
});
