  // ==================
  // Specify Test Files
  // ==================
  // Define which test specs should run. The pattern is relative to the directory
  // of the configuration file being run.
  //
  // The specs are defined as an array of spec files (optionally using wildcards
  // that will be expanded). The test for each spec file will be run in a separate
  // worker process. In order to have a group of spec files run in the same worker
  // process simply enclose them in an array within the specs array.
  //
  // The path of the spec files will be resolved relative from the directory of
  // of the config file unless it's absolute.
  //
  specs: ['./test/e2e/*.e2e.js'],
  // Patterns to exclude.
  exclude: [
    // 'path/to/excluded/files'
  ],
  //
  // ============
  // 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: 10,
  //
  // If you have trouble getting all important capabilities together, check out the
  // Sauce Labs platform configurator - a great tool to configure your capabilities:
  // https://saucelabs.com/platform/platform-configurator

  // =====
  // Hooks
  // =====
  // WebdriverIO provides several hooks you can use to interfere with the test process in order to enhance
  // it and to build services around it. You can either apply a single function or an array of
  // methods to it. If one of them returns with a promise, WebdriverIO will wait until that promise got
  // resolved to continue.
