Cannot read property '_getPortal' of undefined when testing a function that uses ToastController .present()

[kamok]

When you have a toast that you present(), it throws this _getPortal error. Here's a basic function that you can invoke in a spec.

private presentToast(message: string): void {
    const toast = this.toastCtrl.create({
      message: message
    });
    toast.present();
  }

There's a stackoverflow post on it, using the technique of mocking the View Controller, which according to the OP, works.

But it hasn't worked for me using the clicker template, even though it uses the same mock. Any thoughts? Can anyone else replicate?

Here's the full error:
