	// ==================
	// 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/**/*.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.
			maxInstances: 5,
			//
			browserName: 'chrome',
			...chromeOptions,
			acceptInsecureCerts: true,
			// If outputDir is provided WebdriverIO can capture driver session logs
			// it is possible to configure which logTypes to include/exclude.
			// excludeDriverLogs: ['*'], // pass '*' to exclude all driver session logs
			// excludeDriverLogs: ['bugreport', 'server'],

	// If you only want to run your tests until a specific amount of tests have failed use
	// bail (default is 0 - don't bail, run all tests).
	bail: 0,
	//
	// 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.
	// If your `url` parameter starts without a scheme or `/` (like `some/path`), the base url
	// gets prepended directly.
	baseUrl: 'http://localhost',

	// Default timeout for all waitFor* commands.
	waitforTimeout: 10000,
	//

	// Test runner services

	// 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.
