How to add providers in angular2 jasmine testing spec since addProvider is deprecated in RC6?

Question

I am trying to write my beforeEach like this so that every it gets the required modules / providers:

beforeEach(() => addProviders([
        BaseRequestOptions,
        MockBackend,
        {
            provide: Http,
            useFactory: (backend: MockBackend, options: BaseRequestOptions) => new Http(backend, options),
            deps: [MockBackend, BaseRequestOptions]
        },
        MyService
    ]));

But since addProviders method is deprecated in RC6, what is a better alternative to add my providers?

Answer 1

Use TestBed from @angular/core/testing to create test modules. For example

beforeEach(() => {
  TestBed.configureTestingModule({
    imports: [ ... ],
    declarations: [ ... ],
    providers: [
      { .. },
      MyService
    ]
  });
});

It's pretty much the same as configuring a regular module except you don't need to export anything.

See more complete examples in the ng2-test-seed. It has examples of testing components also using the TestBed
