    // ==================
    // 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: [specFiles],
    // 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.

    // ===================
    // 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: 'result',
    //
    // Enables colors for log output.
    coloredLogs: true,
    //
    // Saves a screenshot to a given path if a command fails.
    screenshotPath: './test-output/e2e_screenshots/',
    //
    // Set a base URL in order to shorten url command calls. If your url parameter starts
    // with "/", then the base url gets prepended.
    baseUrl: argv.baseUrl || 'http://127.0.0.1:8080',
    //
    // Default timeout for all waitFor* commands.
    waitforTimeout: 15 * 1000,
    //
    // Default timeout in milliseconds for request
    // if Selenium Grid doesn't send response
    connectionRetryTimeout: 90 * 1000,
    //
    // Default request retries count
    connectionRetryCount: 3,
    //
    // 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',

    //     },
    //     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.

    // =====
    // 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.
    //
    // Gets executed once before all workers get launched.
    // onPrepare: function (config, capabilities) {
    // },
    //
    // Gets executed before test execution begins. At this point you can access all global
    // variables, such as `browser`. It is the perfect place to define custom commands.
    // before: function (capabilities, specs) {
    // },
    //
    // Hook that gets executed before the suite starts
    // beforeSuite: function (suite) {
    // },
    //
    // Hook that gets executed _before_ a hook within the suite starts (e.g. runs before calling
    // beforeEach in Mocha)
    // beforeHook: function () {
    // },
    //
    // Hook that gets executed _after_ a hook within the suite starts (e.g. runs after calling
    // afterEach in Mocha)
    // afterHook: function () {
    // },
    //
    // Function to be executed before a test (in Mocha/Jasmine) or a step (in Cucumber) starts.
    // beforeTest: function (test) {
    // },
    //
    // Runs before a WebdriverIO command gets executed.

    // the test.
