using the server variable in ember-cli-mirage tests - ember-cli-mirage

Question

I'm trying to use ember-cli-mirage in my tests but running into problems. I'm using ember and ember-data 2.1.0 so that may have something to do with this.
I'm able to use mirage in development just fine. I've defined factories, routes, scenarios, etc with no problem.
The problem is when i attempt to create models in tests. The test below errors out:
import Ember from 'ember';
import { module, test } from 'qunit';
import startApp from 'frontend/tests/helpers/start-app';
let application;
module('Acceptance | Customer', {
beforeEach() {
application = startApp();
},
afterEach() {
Ember.run(application, 'destroy');
}
});
test('viewing customers', function(assert) {
server.createList('customer', 2);
visit('/admin/customers');
andThen(() => assert.equal(find('#customers-table tbody tr').length, 2));
});
This results in:
not ok 1 PhantomJS 1.9 - Acceptance | Customer: viewing customers

Should I be bootstrapping mirage somewhere?

Answer 1

This is actually caused by Phantom 1.9 not having bind (you can see in the error message, undefined refers to bind).
If you view the other notes section of the Installation docs you'll see you can get around this by installing ember-cli-es5-shim (or upgrading to PhantomJS 2.0).
