ember-qunit

Latest NPM release TravisCI Build Status

ember-qunit simplifies testing of Ember applications with QUnit by providing QUnit-specific wrappers around the helpers contained in ember-test-helpers.

Requirements

If you need support for Node 4 or older Ember CLI versions please use v3.x of this addon.

Installation

ember-qunit is an Ember CLI addon, so install it as you would any other addon:

$ ember install ember-qunit

Some other addons are detecting the test framework based on the installed addon names and are expecting ember-cli-qunit instead. If you have issues with this then ember install ember-cli-qunit, which should work exactly the same.

Upgrading

For instructions how to upgrade your test suite to the latest testing APIs, please read our Migration Guide.

Usage

The following section describes the use of ember-qunit with the latest modern Ember testing APIs, as laid out in the RFCs 232 and 268.

For the older APIs have a look at our Legacy Guide.

Setting the Application

Your tests/test-helper.js file should look similar to the following, to correctly setup the application required by @ember/test-helpers:

import Application from '../app';
import config from '../config/environment';
import { setApplication } from '@ember/test-helpers';
import { start } from 'ember-qunit';

setApplication(Application.create(config.APP));

start();

Also make sure that you have set ENV.APP.autoboot = false; for the test environment in your config/environment.js.

Setup Tests

The setupTest() function can be used to setup a unit test for any kind of "module/unit" of your application that can be looked up in a container.

It will setup your test context with:

For example, the following is a unit test for the SidebarController:

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

module('SidebarController', function(hooks) {
  setupTest(hooks);

  // Replace this with your real tests.
  test('exists', function() {
    let controller = this.owner.lookup('controller:sidebar');
    assert.ok(controller);
  });
});

Setup Rendering Tests

The setupRenderingTest() function is specifically designed for tests that render arbitrary templates, including components and helpers.

It will setup your test context the same way as setupTest(), and additionally:

import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render } from '@ember/test-helpers';
import hbs from 'htmlbars-inline-precompile';

module('GravatarImageComponent', function(hooks) {
  setupRenderingTest(hooks);

  test('renders', async function() {
    await render(hbs`{{gravatar-image}}`);
    assert.ok(this.element.querySelector('img'));
  });
});

Setup Application Tests

The setupApplicationTest() function can be used to run tests that interact with the whole application, so in most cases acceptance tests.

On top of setupTest() it will:

import { module, test } from 'qunit';
import { setupApplicationTest } from 'ember-qunit';
import { visit, currentURL } from '@ember/test-helpers';

module('basic acceptance test', function(hooks) {
  setupApplicationTest(hooks);

  test('can visit /', async function(assert) {
    await visit('/');
    assert.equal(currentURL(), '/');
  });
});
