  // Specify Test Files
  // ==================
  // Define which test specs should run. The pattern is relative to the directory
  // from which `wdio` was called. Notice that, if you are calling `wdio` from an
  // NPM script (see https://docs.npmjs.com/cli/run-script) then the current working
  // directory is where your package.json resides, so `wdio` will be called from there.

  // ============
  // Capabilities
  // ============
  // Define your capabilities here. WebdriverIO can run multiple capabilties at the same
  // time. Depending on the number of capabilities, WebdriverIO launches several test
  // sessions. Within your capabilities you can overwrite the spec and exclude option in
  // order to group specific specs to a specific capability.
  //
  // If you have trouble getting all important capabilities together, check out the
  // Sauce Labs platform configurator - a great tool to configure your capabilities:
  // https://docs.saucelabs.com/reference/platforms-configurator

  // Initialize the browser instance with a WebdriverIO plugin. The object should have the
  // plugin name as key and the desired plugin options as property. Make sure you have
  // the plugin installed before running any tests. The following plugins are currently
  // available:
  // WebdriverCSS: https://github.com/webdriverio/webdrivercss
  // WebdriverRTC: https://github.com/webdriverio/webdriverrtc
  // Browserevent: https://github.com/webdriverio/browserevent

  // Framework you want to run your specs with.
  // The following are supported: mocha, jasmine and cucumber
  // see also: http://webdriver.io/guide/testrunner/frameworks.html
  //
  // Make sure you have the node package for the specific framework installed before running
  // any tests. If not please install the following package:
  // Mocha: `$ npm install mocha`
  // Jasmine: `$ npm install jasmine`
  // Cucumber: `$ npm install cucumber`
  framework: 'jasmine',
  //
  // Test reporter for stdout.
  // The following are supported: dot (default), spec and xunit

    // The Jasmine framework allows it to intercept each assertion in order to log the state of the application
    // or website depending on the result. For example it is pretty handy to take a screenshot everytime
    // an assertion fails.
