ember-qunit
![CI Build Status](https://github.com/emberjs/ember-qunit/workflows/CI/badge.svg)
ember-qunit simplifies testing of Ember applications with
QUnit by providing QUnit-specific wrappers around the
helpers contained in
ember-test-helpers.
Requirements
- Ember.js v4.0 or above
- Ember Auto Import v2 or above (or Embroider)
- Node.js v16 or above
- ember-cli ~v4.8.1, ~v4.12.2, >= v5.1
If you need support for Node 14 please use v6.2 of this addon.
If you need support for Node 13 or older Ember CLI versions please use v4.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 to the latest version, 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:
this.owner
to interact with Ember's Dependency Injection
systemthis.set()
, this.setProperties()
, this.get()
, and this.getProperties()
this.pauseTest()
method to allow easy pausing/resuming of tests
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);
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, find } from '@ember/test-helpers';
import { hbs } from 'ember-cli-htmlbars';
module('GravatarImageComponent', function(hooks) {
setupRenderingTest(hooks);
test('renders', async function() {
await render(hbs`{{gravatar-image}}`);
assert.ok(find('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(), '/');
});
});
Configuration
Configuration is optionally managed via @embroider/macros
To configure ember-qunit
, in your ember-cli-build.js
, add:
'use strict';
const EmberApp = require('ember-cli/lib/broccoli/ember-app');
module.exports = function (defaults) {
const app = new EmberApp(defaults, {
'@embroider/macros': {
setConfig: {
'ember-qunit': {
disableContainerStyles: true,
theme: 'qunit-default',
},
},
},
});
};
