How to mock router.navigateByUrl(...).then in Angular with Karma and Jasmine

My problem is pretty simple, I use navigateByUrl() then then() in this way:

this.router
.navigateByUrl(PAGE1, {
  skipLocationChange: true
})
.then(() => {
  this.router.navigate([PAGE2]);
});

and I mock navigate, navigateByUrl and then this way:

const mockRouter = {
  navigate: () => {},
  navigateByUrl(url: string) { return url; },
  then: () => {}
};

It works well for navigate and navigateByUrl but it doesn't work for then and I don't know how to mock this function. How can I proceed?

Thanks to jonrsharpe advise i found the solution. The solution was to mock navigateByUrl this way:

navigateByUrl: () => {
    return {
      then: () => {}
    }
  }
