How to convert unit tests with injections?

[alexander-alvarez]

I have some injections on my controller (inside of an engine) which worked, but after running the codemod I'm getting errors:

Attempting to inject an unknown injection: 'router:main

I imagine it's because the registry in the new API is isolated?

Should we be manually registering services, or is there a different desired change?

const resolver = engineResolverFor('my-engine');

module('Unit | Controller | my controller', function(hooks) {
  setupTest(hooks, {
    resolver
  });

  test('injection of services', function(assert) {
      // error occurs here
      let controller = this.owner.factoryFor('controller:my-controller').create({});
    });

});

I need to see how this actually worked before, I'm not sure the best path forward here.

I believe that this might have been fixed automatically when using ember-qunit@3.0.0 and use setApplication (like ember-cli/ember-cli#7437). Can you double check if using setApplication properly adds router:main to the registry?

On second thought, I'm not 100% sure if we also need changes to the engineResolverFor helper method also (and internally create the engine instance exactly how ember itself creates them normally)...

@alexander-alvarez - Any chance you could whip up a demo repo that I could use to step through?

No problem... I'll try to set something up Monday night

So I don't know if it's just not my day, but I'm getting a lot of weird behavior on a clean branch.
I can't seem to test with a live service injection into a controller in the old mode, as well as the new mode. https://github.com/alexander-alvarez/ember-qunit-engine-injection-repro/blob/master/tests/unit/controllers/application-test.js#L10

Except for registering models (how should we do this ?) it seems the new style is working

Sorry this isn't much help. Been an awfully head-scratchy night
