ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.

Advanced tools
Test helpers for testing Ember CLI addons inside the context of a real Ember app.
Previously, it was difficult to do real integration testing with Ember
CLI addons because the process of creating a new Ember app is very slow, due
to the required npm install
and bower install
steps.
This package automates the process of creating a new Ember CLI app and caching its npm and Bower dependencies, so each test run can get a fresh app in very little time. Best of all, you'll be testing your addon in a real app so you can catch integration issues early.
Stability Note: API likely to change
npm install ember-cli-addon-tests --save-dev
var expect = require('chai').expect;
var RSVP = require('rsvp');
var request = RSVP.denodeify(require('request'));
var AddonTestApp = require('ember-cli-addon-tests').AddonTestApp;
describe('serve assets acceptance', function() {
this.timeout(300000);
var app;
before(function() {
app = new AddonTestApp();
return app.create('dummy')
.then(function() {
return app.startServer({
command: 'fastboot',
additionalArguments: ['--serve-assets']
});
});
});
after(function() {
return app.stopServer();
});
it('/assets/vendor.js', function() {
return request('http://localhost:49741/assets/vendor.js')
.then(function(response) {
expect(response.statusCode).to.equal(200);
expect(response.headers["content-type"]).to.eq("application/javascript");
expect(response.body).to.contain("Ember =");
});
});
it('/assets/dummy.js', function() {
return request('http://localhost:49741/assets/dummy.js')
.then(function(response) {
expect(response.statusCode).to.equal(200);
expect(response.headers["content-type"]).to.eq("application/javascript");
expect(response.body).to.contain("this.route('posts')");
});
});
});
See the ember-cli-fastboot tests for real world examples.
Creates a new app for testing.
var AddonTestApp = require('ember-cli-addon-tests').AddonTestApp;
app = new AddonTestApp();
This starts the process of actually creating a new Ember CLI app on
disk. The first run may take several minutes while the npm install
happens. Subsequent runs will be faster. Pass the name of the
application as the first argument.
// returns a promise
app.create('my-app');
You can customize the app by supplying an options hash:
// returns a promise
app.create('my-app', {
emberVersion: 'release'
});
The following options exist:
option | description | defaults to |
---|---|---|
emberVersion | Set the ember version the app should be created with, as you would in your bower.json | canary |
emberDataVersion | Set the version of ember-data, as you would in your package.json | emberjs/data#master |
fixturesPath | The path to look for your fixture files (see below) | test/fixtures |
You will probably want to add files to the Ember application that you want to test your addon with. Ember CLI Addon Tests will automatically copy fixtures on top of the base Ember CLI app, based on the name of the application that you created.
For example, if you call app.create('my-app')
, the test helper will
look for a file called test/fixtures/my-app
in your addon's directory
and will copy them to the test app, overwriting any files that exist.
package.json
If your addon depends on end developers configuring their application's
package.json
, you can edit the test app's package.json
with the
editPackageJSON
method:
// runs synchronously
app.editPackageJSON(function(pkg) {
pkg.devDependencies['fake-addon'] = "*";
pkg.devDependencies['fake-addon-2'] = "*";
});
You should not call app.editPackageJSON()
until after the create()
promise has resolved.
To test the assets served by Ember CLI, you can start the server (i.e.,
ember server
) via the startServer()
method:
// returns a promise
app.startServer();
If you want to run a different command that starts the server, you can
pass the command
option:
// Runs `ember fastboot` inside the app instead of `ember server`
app.startServer({
command: 'fastboot'
});
You can also pass additional command line arguments via the
additionalArguments
option:
// equivalent to `ember server --serve-assets`
app.startServer({
additionalArguments: ['--serve-assets']
});
After your tests, stop the development server via stopServer()
.
app.stopServer();
You can run arbitrary commands inside the test app via the run()
method. Takes a command and optional arguments.
// returns a promise
app.run('ember', 'build', '--verbose');
You can run commands using the app's version of Ember CLI via the
runEmberCommand
method:
// equivalent to `ember fastboot:build --environment production`
app.runEmberCommand('fastboot:build', '--environment', 'production');
Temporary directories are automatically deleted once the process exits.
