  // Define which test specs should run. The pattern is relative to the directory
  // from which `wdio` was called.
  //
  // 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.
  //
  // 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.

  // 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.
