karma-detect-browsers

Karma runner plugin for detecting all browsers installed on the current system. Adds all found browsers to the browser array in the karma config file.

    "karma": "^0.13",
    "karma-detect-browsers": "^2.0"
  }
}

You can simply do it by:

npm install karma-detect-browsers --save-dev

Get started

add detectBrowsers as framework and plugin to your karma config file
add the karma browser plugins for all the browser installed on your system
add the karma browser plugins to the package.json file

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['detectBrowsers'],
 
    plugins: [
      'karma-chrome-launcher',
      'karma-edge-launcher',
      'karma-firefox-launcher',
      'karma-ie-launcher',
      'karma-safari-launcher',
      'karma-safaritechpreview-launcher',
      'karma-opera-launcher',
      'karma-phantomjs-launcher',
      'karma-detect-browsers'
    ]
  });
};

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['detectBrowsers'],
 
    // configuration
    detectBrowsers: {
      // enable/disable, default is true
      enabled: true,
 
      // enable/disable phantomjs support, default is true
      usePhantomJS: true,
 
      // use headless mode, for browsers that support it, default is false
      preferHeadless: true,
 
      // post processing of browsers list
      // here you can edit the list of browsers used by karma
      postDetection: function(availableBrowsers) {
        /* Karma configuration with custom launchers
          customLaunchers: {
            IE9: {
              base: 'IE',
              'x-ua-compatible': 'IE=EmulateIE9'
            }
          }
        */
 
          //Add IE Emulation
          var result = availableBrowsers;
 
          if (availableBrowsers.indexOf('IE')>-1) {
            result.push('IE9');
          }
 
          //Remove PhantomJS if another browser has been detected
          if (availableBrowsers.length > 1 && availableBrowsers.indexOf('PhantomJS')>-1) {
            var i = result.indexOf('PhantomJS');
 
            if (i !== -1) {
              result.splice(i, 1);
            }
          }
 
          return result;
        }
    },
 
    plugins: [
