how to enumerate all route names in an ember test

we need to get a list of all route names from router.js in a test. preferably a lower level test (unit/integration).

use case for context: we have metadata that is required for all routes. this test is to make sure that the appropriate metadata was added, and not forgotten, when a new route is added.

similar questions here and here have been asked, but attempts to adopt/modify those solutions within a test have not been fruitful.

here's how I've managed to do it in an acceptance test.

here's what I don't like about this solution:

  • it has the higher overhead of an acceptance test.
  • it uses private APIs.

the private APIs are used in ember-inspector though, so if it breaks in the future, we should be able to reference whatever they've changed in that repo.

import { module, test } from 'qunit';
import { setupApplicationTest } from 'ember-qunit';

module('Acceptance | route metadata test', hooks => {
  setupApplicationTest(hooks);

  test('we can get route names', function(assert) {

    const router = this.owner.lookup('router:main');

    router.setupRouter();

    const routeNames = router._routerMicrolib.recognizer.names;
    assert.ok(Object.keys(routeNames).length > 0);

  });
});

the test only asserts that we have route names. for the original use case, it is trivial to change this code to iterate over routeNames.

ember-cli: 3.5.0
node: 8.12.0

the need to call setupRouter() was found via this issue
