	// Runner Configuration
	// ====================
	//
	// WebdriverIO allows it to run your tests in arbitrary locations (e.g. locally or
	// on a remote machine).
	runner: 'local',
	//
	// Override default path ('/wd/hub') for chromedriver service.
	path: '/',
	//
	// ==================
	// 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/browser/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',
		'goog:chromeOptions': {
			args: process.env.CI ? [ 'headless', 'disable-gpu' ] : [],
			binary: whichChrome,
		},
		// 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'],
	} ],
	//
	// ===================
	// Test Configurations
	// ===================
	// Define all options that are relevant for the WebdriverIO instance here
	//
	// Level of logging verbosity: trace | debug | info | warn | error | silent
	logLevel: 'warn',
	//
	// Set specific log levels per logger
	// loggers:
	// - webdriver, webdriverio
	// - @wdio/applitools-service, @wdio/browserstack-service, @wdio/devtools-service, @wdio/sauce-service
	// - @wdio/mocha-framework, @wdio/jasmine-framework
	// - @wdio/local-runner, @wdio/lambda-runner
	// - @wdio/sumologic-reporter
	// - @wdio/cli, @wdio/config, @wdio/sync, @wdio/utils
	// Level of logging verbosity: trace | debug | info | warn | error | silent

	// 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: 'https://commons.wikimedia.beta.wmflabs.org',
	// baseUrl: 'https://test-commons.wikimedia.org',
	//
	// Default timeout for all waitFor* commands.
	waitforTimeout: 10000,
	//
	// Default timeout in milliseconds for request
	// if Selenium Grid doesn't send response
	connectionRetryTimeout: 90000,
	//
	// Default request retries count
	connectionRetryCount: 3,
	//
	// 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.
	services: [ 'chromedriver' ],

	// Framework you want to run your specs with.
	// The following are supported: Mocha, Jasmine, and Cucumber
	// see also: https://webdriver.io/docs/frameworks.html

	// before running any tests.

	// See the full list at http://mochajs.org/
	mochaOpts: {
		ui: 'bdd',

	//
	// =====
	// 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.
