Build Status

kommando is a configurable cross browser functional / acceptance test launcher (using Webdriver).

It helps you to get started writing functional cross browser tests using JavaScript without knowing details how to properly setup the various Webdriver servers locally, while still allowing to run your created tests on an existing Selenium Grid (including SauceLabs).

For each test launch you can configure a test-runner that should be used to execute tests (currently jasmine-node or mocha) and you can tell which Webdriver JS lib should be used to create a Webdriver client session (e.g. selenium-webdriver or wd) per browser. The configured Webdriver client session then gets injected into the test runner execution context and can then be used there.

This project is aimed for finding the best suited approach to write your functional cross browser tests using JavaScript by allowing you to choose a test style (jasmine, mocha) you already are familiar with and using a Webdriver JS library that you like the most. To simplify working with the promise-based API of selenium-webdriver kommando contains runner modules that tie the test runner to the control-flow of this promise-based API.

Prerequisites

  • Java (>= 1.7 if you want to use iOS-Driver)
  • [optional] Appium (can be installed through npm install appium -g)

Installation

npm install kommando -g

Writing your first functionl test for kommando

// mytest.js (using jasmine syntax)
describe('github', function() {
  it('reads the "title"', function(done) {
    // the global "kommando.browser" provides the initialized Webdriver session
    // using "selenium-webdriver" as default Webdriver library
    kommando.browser.get('https://www.github.com').then(function() {
      return kommando.browser.findElement(kommando.webdriver.By.className('heading'));
    }).then(function(heading) {
      return heading.getText();
    }).then(function(text) {
      expect(text).toBe('Build software better, together.');
    }).then(done, done); // handle promise error / success within "it"
  });
});

Executing that test

You can invoke kommando either via command-line:

# this will execute your test using PhantomJS (default)
kommando mytest.js

or via Node.js:

// also executing tests using PhantomJS
var kommando = require('kommando');
kommando({
  tests: ['./mytest.js']
});

Executing test in Chrome, Firefox and PhantomJS using CLI:

kommando -b chrome -b firefox -b phantomjs mytest.js

or via Node.js:

var kommando = require('kommando');
kommando({
  browsers: ['chrome', 'firefox', 'phantomjs'],
  tests: ['./mytest.js']
});
