  // ============
  // Capabilities
  // ============
  // Define your capabilities here. WebdriverIO can run multiple capabilities 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 options in
  // order to group specific specs to a specific capability.
  //
  // First, you can define how many instances should be started at the same time. Let's
  // say you have 3 different capabilities (Chrome, Firefox, and Safari) and you have
  // set maxInstances to 1; wdio will spawn 3 processes. Therefore, if you have 10 spec
  // files and you set maxInstances to 10, all spec files will get tested at the same time
  // and 30 processes will get spawned. The property handles how many capabilities
  // from the same test should run tests.
  //
  maxInstances: !DEBUG ? 1 : 1,
  //
  // 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

  // ===================
  // Test Configurations
  // ===================
  // Define all options that are relevant for the WebdriverIO instance here
  //
  // By default WebdriverIO commands are executed in a synchronous way using
  // the wdio-sync package. If you still want to run your tests in an async way
  // e.g. using promises you can set the sync option to false.
  sync: true,
  //
  // Level of logging verbosity: silent | verbose | command | data | result | error
  logLevel: 'error',
  //
  // Enables colors for log output.
  coloredLogs: true,
  //
  // Saves a screenshot to a given path if a command fails.
  screenshotPath: './errorShots/',
  //
  // Set a base URL in order to shorten url command calls. If your url parameter starts
  // with "/", then the base url gets prepended.
  baseUrl: 'http://localhost:8123',

  //
  // Default timeout in milliseconds for request
  // if Selenium Grid doesn't send response
  connectionRetryTimeout: 5 * 60 * 1000,
  //
  // Default request retries count
  connectionRetryCount: 1,
  //
  // Initialize the browser instance with a WebdriverIO plugin. The object should have the
  // plugin name as key and the desired plugin options as properties. 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
  // plugins: {
  //     webdrivercss: {
  //         screenshotRoot: 'my-shots',
  //         failedComparisonsRoot: 'diffs',
  //         misMatchTolerance: 0.05,
  //         screenWidth: [320,480,640,1024]
  //     },
  //     webdriverrtc: {},
  //     browserevent: {}
  // },
  //
  // Test runner services
  // Services take over a specific job you don't want to take care of. They enhance
  // your test setup with almost no effort. Unlike plugins, they don't add new
  // commands. Instead, they hook themselves up into the test process.

  // Framework you want to run your specs with.
  // The following are supported: Mocha, Jasmine, and Cucumber

  // Make sure you have the wdio adapter package for the specific framework installed
  // before running any tests.
