茉莉花-如何在callFake间谍中链接`.then`和`.finally`？

Question

I have the following function, that does a service call with a promise and a .finally :

myService.getStuff().then(function() {
   this.doStuffWhenServiceOK();
}, function () {
   this.doStuffWhenServiceFails();
}).finally(function() {
   this.doFinally();
});

I am spying on this service with the following spy:

spyOn(myService, 'getStuff').and.callFake(function() {
   return {
     then: function (succesFn, errorFn) {
       return succesFn();
     }
   };
});

The problem is that the test complains that the .finally is not known. Just adding it after .then does not seem to be a solution...

return {
  then: function(successFn) { 
    return successFn();
  },
  finally: function(successFn) {
    return successFn();
  }
}

Who knows how to chain .then and .finally in the callFake spy?

I work with Angular 1.

Return a finally function.

function then(succesFn, errorFn) {
    succesFn(); 
    return {finally:function() {}};
}
