karma-sauce2-launcher v0.5.0

Karma-Sauce2-Launcher

This is forked and updated version of the Karma-Sauce-Launcher

Installation

Install karma-sauce2-launcher as a devDependency in your package.json:

npm install karma-sauce2-launcher --save-dev

Usage

Run your unit tests on Sauce Labs' browser cloud!

This launcher is dependant on the changes made in Karma Pull Request 2793 Prior to acceptance you will need to make the following changes to the Karma package:

/node_modules/karma/lib/browsers.js

add this.allResults = [] below line 68 replace line 213 this.onResult{...} with

  this.onResult = function (result) {
    if (result.length) {
      this.allResults = result
      return result.forEach(this.onResult, this)
    }

    if (this.isReady()) {
      return
    }

    this.lastResult.add(result)

    emitter.emit('spec_complete', this, result)
    refreshNoActivityTimeout()
  }

This launcher is typically used in CI to run your unit tests across many browsers and platforms on Sauce Labs. It is expected that you are already familiar with Karma when configuring this launcher, so if you are new to Karma, head over to the Karma website.

Adding karma-sauce-launcher to an existing Karma config

To configure karma-sauce2-launcher, you need to add two properties to your top-level Karma config, sauceLabs and customLaunchers, set the browsers array to use Sauce Labs browsers, and add the sauceLabs reporter.

The sauceLabs object defines global properties for each browser/platform while the customLaunchers object configures individual browsers. The sauceLabs reporter allows your tests results to be properly displayed on https://saucelabs.com. Here is a sample Karma config to get the launcher running:

Note: this config assumes that process.env.SAUCE_USERNAME and process.env.SAUCE_ACCESS_KEY are set.

module.exports = function(config) {
  // Example set of browsers to run on Sauce Labs
  // Check out https://saucelabs.com/platforms for all browser/platform combinations
  var customLaunchers = {
    sl_chrome: {
      base: 'SauceLabs',
      browserName: 'chrome',
      platform: 'Windows 7',
      version: '35'
    },
    sl_firefox: {
      base: 'SauceLabs',
      browserName: 'firefox',
      version: '30'
    },
    sl_ios_safari: {
      base: 'SauceLabs',
      browserName: 'iphone',
      platform: 'OS X 10.9',
      version: '7.1'
    },
    sl_ie_11: {
      base: 'SauceLabs',
      browserName: 'internet explorer',
      platform: 'Windows 8.1',
      version: '11'
    }
  }

  config.set({

    // The rest of your karma config is here
    // ...
    sauceLabs: {
        testName: 'Web App Unit Tests'
    },
    customLaunchers: customLaunchers,
    browsers: Object.keys(customLaunchers),
    reporters: ['dots', 'saucelabs'],
    singleRun: true
  })
}

sauceLabs config properties are shared across all browsers

customLaunchers config properties

The customLaunchers object has browser names as keys and configs as values. Documented below are the different properties which you can configure for each browser/platform combo.

Note: You can learn about the available browser/platform combos on the Sauce Labs platforms page, platforms configurator page and REST API page.

This defines the base configuration for the launcher. In this case it should always be SauceLabs so that browsers can use the base Sauce Labs config defined at the root sauceLabs property.

Version of the browser to use.

Accepted values: 'portrait' || 'landscape'

Set this string if your unit tests need to run on a particular mobile device orientation for Android Browser or iOS Safari.
