ember-data-factory-guy: MockFindRecord.fails() does not capture preflighted requests

Oddly the example I showed was fine because the mock model that was returning was the same one returned by the mockFindRecord. In your case that was also the case ( I think ) BUT the big difference is: This test that passes is expecting the model to be found.

You were expecting a find to fail when that model was in the ember data store. That just did not sit well with ember data. That is why for a fail you should not use returns({model: myModel}).fails() just do .fails on the mock and stop there.

I am going to fix the docs to show that and even put a fails test in the acceptance tests as well If you can think of anything else to document, let me know

you are making one very small error I will post this again with your setup too, ( that is clue ) and give you 5 minutes to figure it out:

 beforeEach(function() {
     broadcastMock = mockFindRecord('broadcast');
     broadcast = make('broadcast', {  title: 'This is the title'  })
  });
 describe('HTTP 404 from backend', function() {
      it('shows a 404 error page', function() {
        broadcastMock.fails({status: 404, response: {errors: {status: '404', name: ["broadcast not found"]}}});

        visit('/broadcast/' + broadcast.get('id'));

        return andThen(() => {
          expect(find('p').text()).to.have.string('We could not find that page');
        });
      });

If after 5 mins you don’t get it I will give more clues 😃
