Ember CLI generated unit test is failing on it exists

817 views Asked by At

I have an order controller in controllers/order.js

import Ember from 'ember';

export default Ember.Controller.extend({
  needs: "orders"
});

This has a test in /tests/unit/controllers/order-test.js

import { moduleFor, test } from 'ember-qunit';

moduleFor('controller:order', {
// Specify the other units that are required for this test.
// needs: ['controller:foo']
});

// Replace this with your real tests.
test('it exists', function(assert) {
var controller = this.subject();
assert.ok(controller);
});

router.js looks like this

this.resource('orders', function() {
  this.resource('order', { path: ":order_id"} , function() {
  });
  this.route('create');
});

The idea being I have a /orders/ route where someone clicks an order in a table and then below the table it shows further details on the order and the route is now /orders/1 for example.

The unit tests fails with:

What do I need to change in my setup or test to get the unit test passing here?

You need to inform the test of the controller dependencies. In order to do this, change your moduleFor method to the following:

moduleFor('controller:order', {
  needs: ['controller:orders']});
