TestSquad

Travis-CI Code Climate Test Coverage Gem Gem

Running JavaScript tests on your Rails app, the easy way.

Installation

Add these lines to your application's Gemfile:

group :development, :test do
  gem "test_squad"
end

And then execute:

$ bundle

Usage

After installing TestSquad, generate your tests skeleton. The generator will detect if you're using RSpec or TestUnit and will generate the javascript directory based on that detection. Just use the command rails generate test_squad:install --framework FRAMEWORK.

$ rails generate test_squad:install --framework jasmine
    create  test/javascript/squad_sample
    create  test/javascript/squad_sample/.keep
    create  test/javascript/spec_helper.js
    source  https://rails-assets.org
     exist  test/javascript
    create  test/javascript/test_squad.rb

If you're already using https://rails-assets.org, you can skip the Gemfile entry with --skip-source.

Running tests

You can run your tests with rake test_squad. You can also visit http://localhost:3000/tests for in-browser testing.

Jasmine

Mocha

QUnit

Terminal

Ember

Configure Ember

When using the Ember framework, you must configure your application name. It'll default to your Rails application name.

//= require application
//= require_self
//= require_tree ./components
//= require_tree ./models
//= require_tree ./routes
//= require_tree ./unit
//= require_tree ./views

// Set the application.
App = SquadSample;

// Set up Ember testing.
App.rootElement = "#ember-testing";
App.setupForTesting();
App.injectTestHelpers();

To disable all Ember logging, add the following line to test_helper.js, just before the //= require application line.

//= require ./logging

Then create the file spec/javascript/logging.js with this content:

Ember = {ENV: {
  LOG_TRANSITIONS: false,
  LOG_VIEW_LOOKUPS: false,
  LOG_ACTIVE_GENERATION: false,
  LOG_RESOLVER: false,
  LOG_TRANSITIONS: false,
  LOG_TRANSITIONS_INTERNAL: false,
  LOG_VERSION: false
}};

Configure Mocha

By default, Mocha is configured with expect.js. You can use different libraries like should.js or chai.

Just add the dependency to your Gemfile. Use rails-assets-chai or rails-assets-should:

source "https://rubygems.org"
source "https://rails-assets.org"

gem "rails", "4.2.0"
gem "sass-rails", "~> 5.0"
gem "uglifier", ">= 1.3.0"

gem "ember-rails"
gem "rails-assets-jquery"

group :development, :test do
  gem "test_squad", path: "../../test_squad"
  gem "rails-assets-mocha"
  gem "rails-assets-chai"
end

Install the dependency with bundle install. Then require the library on {test/spec}/javascript/spec_helper.js.

//= require application
//= require chai
//= require_self
//= require_tree ./squad_sample

var assert = chai.assert;

mocha.setup("bdd");
mocha.checkLeaks();
mocha.globals(["jQuery"]);
mocha.reporter(mocha.TestSquad);
window.onload = function(){
  mocha.run();
};

Troubleshooting

Route is not available

If you have a catch-all route, add the following line to your config/routes.rb file. This will be required if you configure Ember.js to use history.pushState.

get :tests, to: "test_squad#tests" unless Rails.env.production?

Otherwise you won't be able to to run your in-browser tests.

Using NPM/Bower instead of rails-assets

You may want to use something else (NPM, Bower directly, etc). In this case, the easiest way is adding QUnit's directory to the load path.

Let's configure QUnit from NPM. Create the file package.json like the following:

{
  "name": "myapp",
  "version": "0.0.0",
  "private": true
}

Run the command npm install qunitjs --save-dev to install QUnit. The library will be available at node_modules/qunitjs/qunit. Now modify config/initializers/assets.rb, adding this directory to the load path.

# ...

if Rails.env.development?
  Rails.application.config.assets << Rails.root.join("node_modules/qunitjs/qunit").to_s
end

That's it!

Configuration

The rake task accepts some env variables.

  • TEST_SQUAD_SERVER_HOST: the binding host. Defaults to localhost.
  • TEST_SQUAD_SERVER_PORT: the server port. Defaults to 42424.
  • TEST_SQUAD_SERVER_PATH: the server path. Defaults to /tests.
  • TEST_SQUAD_TIMEOUT: how much time a test can take. Defaults to 10 (seconds).
  • TEST_SQUAD_PHANTOMJS_BIN: set the PhantomJS binary. Defaults to phantomjs.

You can configure these options using the {test,spec}/javascript/test_squad.rb file.

TestSquad.configure do |config|
  config.framework = "qunit"
  config.server_host = "127.0.0.1"
  config.server_port = 42424
  config.server_path = "/tests"
  config.timeout = 10
  config.phantomjs_bin = "phantomjs"
end

Contributing

Before starting, create an issue asking if it'd be a useful/wanted feature. This will avoid wasting your time.

  1. Fork it ( http://github.com/fnando/test_squad/fork )
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request

Remember:

  • Don't mess with versioning.
  • Follow the code style already present.
  • Opening an issue asking if your feature/change will be merged it's recommended, so that you don't waste your time.
