Ember Sinon QUnit

Build Status Ember Observer Score Code Climate Codacy Badge

This addon integrates Sinon & Ember-QUnit via Ember-Sinon, as inspired by Sinon-QUnit.

Why not simply use Ember-Sinon? Two reasons:

  1. Ember-Sinon does not handle cleanup of Ember-QUnit tests. Ember-Sinon-QUnit provides a test method that wraps Ember-QUnit while making each test callback a sandboxed Sinon environment. All spies/stubs created via the sandbox will be automatically restored to their original methods at the end of each test.
  2. Sinon is a framework-agnostic library; as such, Ember-Sinon should be as well. This addon exists to enable Ember-Sinon to remove its QUnit specific functionality, making it easier to utilize Ember-Sinon with other addons like Ember-CLI-Mocha, for example.


ember install ember-sinon-qunit


Import Ember-Sinon-QUnit's test method into your tests in place of Ember-QUnit's test. This creates a Sinon sandbox around that test via Sinon's test API. Then, you can access Sinon's spy, stub, mock, and sandbox methods via this within the test callback:

import { moduleFor } from 'ember-qunit';
import test from 'ember-sinon-qunit/test-support/test';

moduleFor('route:foo', 'Unit | Route | foo');

test('fooTransition action transitions to bar route', function (assert) {
  const route = this.subject();
  const stub = this.stub(route, 'transitionTo');
  assert.ok(stub.calledOnce, 'transitionTo was called once');
  assert.ok(stub.calledWithExactly('bar'), 'bar was passed to transitionTo');

That's it! You can use this test method in place of all Ember-QUnit tests if you want, without any loss of functionality. Or, you can import them both into the same test to be used only when you need Sinon:

import { moduleFor, test } from 'ember-qunit';
import sinonTest from 'ember-sinon-qunit/test-support/test';
