Protractor::Rails

This gem helps you seamlessly setup, run and maintain a angularjs e2e test suite using protractor in a rails application.

Dependencies

Make sure you have Nodejs installed and that you do not need to use sudo to install npm packages

Installation

Add this line to your application's Gemfile:

gem 'protractor-rails'

And then execute the following command to load dependencies on your machine:

$ rake protractor:install

You can test that everything has been set up correctly using the command below. This command will run protractor's example configuration and test file against the http://angular.org website. If everything starts up ok and runs till the end giving you a summary of test results then you are 'good to go'!

$ rake protractor:example

Usage

Initialization

You can initialize your app with protractor rails by running

$ rake protractor:init

Dummy test in local environment

This will generate and template configuration and a dummy example test. Once you have run this you can test that everything has been set up correctly in your local environment by running the following command:

$ rake protractor:spec

This will run a local rails test server, the webdriver selenium server and run protractor against the example_spec.js If everything starts up and runs cleanly you should see the test summary of 1 test 1 pass and 0 failures.

Running your tests

When the rake protractor:init script is run it will create a file spec/javascripts/protractor.conf.js. This file is where you can configure the tests that should be run. [See Protractor Documentation for more details] (https://github.com/angular/protractor/blob/master/docs/getting-started.md).

In this file you can provide patterns for matching your protractor specs. NB: It is recommended that you use a subdirectory such as spec/javascripts/protractor_specs for easy matching and organization

Example

If I have a directory set up for protractor specs in spec/javascripts/protractor_specs/, my configuration file would look something like the below

  // An example configuration file.
  exports.config = {
    // The address of a running selenium server.
    seleniumAddress: 'http://localhost:4444/wd/hub',

    // Capabilities to be passed to the webdriver instance.
    capabilities: {
        'browserName': 'chrome'
    },

    // If you would like to test against multiple browsers, use the multiCapabilities
    // configuration option instead.
    multiCapabilities: [{
        'browserName': 'firefox'
    }, {
        'browserName': 'chrome'
    }],

    // Spec patterns are relative to the current working directly when protractor is called
    specs: ['protractor_specs/**/*.js '],

    baseUrl: 'http://localhost:4000',

    // Options to be passed to Jasmine-node.
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000
    },

    // Specify a version of Jasmine you wish to use. Default version is v1.3
    // Jasmine v2 has many more built-in functions to help with testing,
    // such as beforeAll and afterAll.
    // Jasmine v2 documentation can be found here:
    // http://jasmine.github.io/2.0/introduction.html
    framework: 'jasmine2'
};

Once you have setup your tests as above, running rake protractor:spec will pick up new tests and run them for you.

You can specify the binding for the rails server as an environment variable: rake protractor:spec rails_binding=hostname_or_ip.

Suites

If you want to organise your tests then you can use suites. Replace the specs: line in the above with the following

suites: {
    login: 'protractor_specs/login/*.js',
    user: 'protractor_specs/user/*.js'
},

You can run specific test suites by passing in options to the rake task as per the below example.

$ rake protractor:spec -- --suite suite-name

NOTE You must have the -- first otherwise rake will think the arguments are for rake instead of the task

Run in debug mode

$ DEBUG=true rake protractor:spec

Run a specific spec file

$ rake protractor:spec -- --specs spec-filename

Setup and teardown

There is a task to reset your database to remove items you have created during your tests. This will also seed your database with any fixtures you might have prepared

$ rake protractor:cleanup

This will reset your test database and load in seeds in db/seeds.rb into your test database only.

There is also a convenience function for running cleanup after you have run your tests ready for the next test run.

$ rake protractor:spec_and_cleanup

Task Options

rake protractor:spec

You can control verbosity of logging with the following ENV flags:

rake protractor:spec nolog=y # all quiet
rake protractor:spec nolog_selenium=y # no selenium (just drivers)
rake protractor:spec nolog_rails=y # no rails

Notes about integration tests

Integration tests are MUCH faster than testing things yourself but they are MUCH slower than running unit tests or rspec tests. Keep your integration tests to a minimum and test as much as possible with your normal rails test suite.
