nemisj/grunt-galen

Grunt module for Galen testing.

grunt-galen

Grunt plugin for Galen testing framework

This module includes Galen framework downloader since version 0.5.0 (Galen is also downloadable here).

Warning - Galen framework requires Java runtime environment to work. Java is not included in this module.

Getting started

In the project directory run:

npm install --save-dev grunt-galen

Then add it to the Gruntfile:

grunt.loadNpmTasks('grunt-galen');

Preparing the environment

Galen testing requires three components to run through your tests:

1. Project URL address. (http://127.0.0.1/ counts, of course)
2. Galen testing .spec files. (read more)
3. Target devices / display resolutions.

Writing Galen tests

grunt-galen exposes a useful gl.js module¹, so you can spend more time improving your project, rather than writing the test files.

Test files' main role is to assign .spec files to their target pages of the project. For example example-test.test.js can look like this:

load ('../gl.js');

forAll(config.getDevices(), function (device) {
  // Just like unit test's `it( ... )`
  test('Example on ' + device.deviceName, function () {
    gl.openPage(device, config.getProjectPage());
    
    gl.runSpecFile(device, './test/example-test.spec');
  });
});

This test suite runs the example-test.spec file against the main project page.

Remember that you are not bound to the gl.js framework and, if you are familiar with vanilla Galen API, you are welcome to use it with grunt-galen. (more on Galen javascript API)

¹ Full gl.js docs can be found along with task configuration reference at the bottom of this README.

Configuring your task

Example configuration for a simple Galen task:

galen: {
  local: {
  
    // Check all test.js files in the test directory
    src: ['test/**/*.test.js'],
    options: {
    
      // Run test on the localhost:3000
      url: 'http://127.0.0.1:3000',
      devices: {
        
        // Run tests in firefox browser, scaled to basic desktop resolution
        desktop: {
          deviceName: 'desktop',
          browser: 'firefox',
          size: '1280x800'
        },
        
        // Also run them in firefox, but scaled to iPad screen size
        tablet: {
          deviceName: 'tablet',
          browser: 'firefox',
          size: '768x576'
        }
      }
    }
  }
}

Now just run the command grunt galen:local and enjoy the show!

Grunt task options

options.concat

Combine all galen test files into one to speed up the testing process.

Warning - Do not enable this if you wish to know the number of passed/failed tests. If enabled, number of tests will always be 1.

default: false

options.project

Object containing basic information about the project.

default: undefined

options.project.url

URL of the project. This URL is prioritized over options.url.

default: http://127.0.0.1:80

options.project.name

Name of the project. Can be used in test files via getProjectName().

default: Project

options.url

URL of the project.

Overriden by the options.project.url, if defined.

Project URL is not necessary, although it is passed to test files via configuration and can be easily read in every test suite via getProjectPage() and getProjectSubpage(subpage).

default: http://127.0.0.1:80

options.devices

Object containing device definitions for tests. Each device has to have at least three parameters defined in Galen docs: deviceName, browser and size. (read more)

If you wish to use grunt-galen with Selenium Grid (especially SauceLabs), you may also want to define desiredCapabilites for each device. (read more) (drag-and-drop device configurator)

Warning - All desired capabilities ought to be strings. Therefore tags' arrays, boolean values and numbers have to be cast to strings in the Gruntfile.

default: {}

required: true

options.htmlReport

Set to true, if you wish Galen to generate HTML report for every test suite.

default: false

options.htmlReportDest

Set to desired HTML report directory.

default: ''

options.seleniumGrid

Configuration object for a remote Selenium Grid.

default: disabled

options.seleniumGrid.url

URL address of your Selenium Grid.

Overrides options.seleniumGrid.username and options.seleniumGrid.accessKey. (Either is assumed to be contained in the url or not necessary to access the Selenium Grid)

default: undefined

options.seleniumGrid.username

(Only for SauceLabs) SauceLabs username.

default: undefined

options.seleniumGrid.login

(Only for SauceLabs) SauceLabs login. This most of the time should have the very same value as username, unless you use separate accounts across your team.

default: undefined

options.seleniumGrid.accessKey

(Only for SauceLabs SauceLabs access key.

default: undefined

options.nogl

Set true to disable gl.js functionality for test suites.

default: false

options.cwd

Working directory. (if enabled, gl.js will be created in that directory)

default: ./

GL.js Reference

gl.js is a wrapper for some Galen JavaScript functionality, aimed on making testing easier, faster and more intuitive.

Include

To use gl.js in your test file, you have to load gl.js library. gl.js is created on runtime in your options.cwd directory, so, for example, if your tests are placed under test/ and you haven't modified the options.cwd, you should load ../gl.js in your test suite.

Usage

When included, gl.js exposes its public interface to the test file in the global scope.

Public gl.js API

gl

Main functional interface. Implements several useful functions to speed up your tests.

gl.openPage ([Object] device, [String] url [, [Object] pageElements])

Open target page in the browser on a target device. If page times out, test will be failed.

If pageElements is defined, Galen will attemp to fetch these elements from the webpage.

device* - a device specification

url - a target webpage url (see also config.getProjectPage() and config.getProjectSubpage())

pageElements - a collection of selectors for elements needed in tests (galen docs)

gl.runSpecFile ([Object] device, [String] file [, [Array] tags])

Run a test file on the target device, on the current webpage. This is what Galen is for, after all.

device* - a device specification

file - a path to the .test.js file

tags - a collection of optional Galen tags for the test

gl.quit ()

Terminate all devices and finish testing immediately.

gl.cleanCache ()

Remove all elements, fetched from the current webpage, from the cache storage.

config.getDevices ()

Retrieve devices list for tests. Compatible with Galen #forAll().

config.getProjectName ()

Retrieve project name. ('Project', if undefined)

config.getProjectPage ()

Return main project URL.

config.getProjectSubpage ()

Return main project URL with appended subpage suffix.

config.getSeleniumGrid ()

Get Selenium Grid configuration. Exposes two values:

enabled - Selenium Grid enabled flag

url - Selenium Grid url.

Examples

Example projects are presented in the example/ directory. It is sufficient you go into the directory and run npm install && grunt to test any of the examples there.

Testing

Grunt galen has its testing script npm test, which launches an example on a current version of the script (does not load a script from NPM, uses tasks/galen.js instead). Example includes both local and remote testing.

SauceLabs account for this project is open for everyone who wishes to test the module on a Selenium Grid. Account credentials are available both on SauceLabs page and here:

login: 'gruntgalen-sl',
username: 'gruntgalen-sl',
accessKey: '5fa3a9f6-a912-4294-b254-6041410702f5'
