    // ==================
    // 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.
    //
    specs: [
        './test/specs/**/*Tests.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://docs.saucelabs.com/reference/platforms-configurator
    //
    capabilities: [{
      // maxInstances can get overwritten per capability. So if you have an in-house Selenium
      // grid with only 5 firefox instances available you can make sure that not more than
      // 5 instances get started at a time.

    // Set a base URL in order to shorten url command calls. If your `url` parameter starts
    // with `/`, the base url gets prepended, not including the path portion of your baseUrl.

    // resolved to continue.
