Karma

Applies to CrossBrowserTesting SaaS, last modified on October 22, 2021

You can check out the repository used in this documentation here: Karma Repo

Run your Karma tests on CrossBrowserTesting's platform.

A large portion of this code was originally taken and modified from Actano/Marcus Mennemeier's karma-cbt-launcher. The original code can be found here.

Install

npm install karma-cbt-launcher --save-dev

Usage

Setup your tests in Karma as you normally would and modify your config file with the customLaunchers and cbtConfig values. See the example directory for a sample test and karma config file.

// karma.conf.js
module.exports = (config) => {
  config.set({
    singleRun: true,
    frameworks: ['jasmine'],
    plugins: [
      'karma-*',
      'karma-cbt-launcher'
    ],
    preprocessors: {
      'tests/*.html': ['html2js']
    },
    files: [
      'tests/*.js',
      'tests/index.html'
    ],
    logLevel: config.LOG_DEBUG,
    browsers: [
      'win7_ie11',
      'win10_edge20',
    ],
    reporters: [
      'progress',
      'CrossBrowserTesting',
    ],
    cbtConfig: {
      username: 'CBT_USERNAME',
      authkey: 'CBT_AUTHKEY',
    },
    customLaunchers: {
      win7_ie11: {
        base: 'CrossBrowserTesting',
        browserName: 'win7_ie11',
        browser_api_name: 'IE11',
        os_api_name: 'Win7x64',
        screen_resolution: '1366x768',
      },
      win10_edge20: {
        base: 'CrossBrowserTesting',
        browserName: 'win10_edge20',
        browser_api_name: 'Edge20',
        os_api_name: 'Win10',
        screen_resolution: '1920x1080',
      },
    },
  })
}

You can also specify the username and authkey using environment variables: CBT_USERNAME and CBT_AUTHKEY

Reporter

A custom reporter 'CrossBrowserTesting' is also included that will mark a test as pass if all tests return success. If a single test returns failed, the entire suite for that device will be marked failed on the CrossBrowserTesting results page. The results message will also be set with the number of tests passed and the number that failed.
