Unit tests fail because of usage of Loading-/ToastController

[ivarreukers]

Short description of the problem:

note: my tests are working fine without a LoadingController
Unit tests fail because, use of LoadingController. This is caused because the LoadingController cannot be provided it seems. This issue would also relate to ex. the NavParams. Just how would one mock them/use them in TestBed

What behavior are you expecting?

That the tests will execute.

Steps to reproduce:

1. Clone marcoturi's https://github.com/marcoturi/ionic2-boilerplate
2. Setup a component with a LoadingController in the constructor
3. Try to create an instance with angular's TestBed.

TestBed.configureTestingModule({
    declarations: [EventsPage],
    schemas: [CUSTOM_ELEMENTS_SCHEMA],
    providers: [
      {provide: APICaller, useValue: mockAPICaller},
      {provide: NavController, useValue: mockNavController },
      {provide: LoadingController, useValue: ???????}, //it seems like everything I try to enter here fails.
    ],
    imports: [FormsModule]
  });

edit: NavParams is able to stay using default NavParams. When using useClass: LoadingController the compiler complains about App! being undefined

If you're injecting LoadingController, you also need to inject anything that it depends on, or create Mocks.

I'm going to close this for now as this is more of a question than an issue.

Thanks,

So how would you mock the App it asks for? Ionic's mockIonicApp doesnt work
