/**
 * New generation Selenium WebDriver module.
 *
 * ## Local Testing
 *
 * ### Selenium
 *
 * To run Selenium Server you need [Java](https://www.java.com/) as well as Chrome or Firefox browser installed.
 *
 * 1. Download [Selenium Standalone Server](http://docs.seleniumhq.org/download/)
 * 2. To use Chrome, install [ChromeDriver](https://sites.google.com/a/chromium.org/chromedriver/getting-started). To use Firefox, install [GeckoDriver](https://github.com/mozilla/geckodriver).
 * 3. Launch the Selenium Server: `java -jar selenium-server-standalone-3.xx.xxx.jar`. To locate Chromedriver binary use `-Dwebdriver.chrome.driver=./chromedriver` option. For Geckodriver use `-Dwebdriver.gecko.driver=./geckodriver`.
 * 4. Configure this module (in `acceptance.suite.yml`) by setting `url` and `browser`:
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: 'http://localhost/'
 *              browser: chrome # 'chrome' or 'firefox'
 * ```
 *
 * Launch Selenium Server before executing tests.
 *
 * ```
 * java -jar "/path/to/selenium-server-standalone-xxx.jar"
 * ```
 *
 * ### ChromeDriver
 *
 * To run tests in Chrome browser you may connect to ChromeDriver directly, without using Selenium Server.
 *
 * 1. Install [ChromeDriver](https://sites.google.com/a/chromium.org/chromedriver/getting-started).
 * 2. Launch ChromeDriver: `chromedriver --url-base=/wd/hub`
 * 3. Configure this module to use ChromeDriver port:
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: 'http://localhost/'
 *              window_size: false # disabled in ChromeDriver
 *              port: 9515
 *              browser: chrome
 *              capabilities:
 *                  chromeOptions: # additional chrome options
 * ```
 *
 * Additional [Chrome options](https://sites.google.com/a/chromium.org/chromedriver/capabilities) can be set in `chromeOptions` capabilities.
 *
 *
 * ### PhantomJS
 *
 * PhantomJS is a [headless browser](https://en.wikipedia.org/wiki/Headless_browser) alternative to Selenium Server that implements
 * [the WebDriver protocol](https://code.google.com/p/selenium/wiki/JsonWireProtocol).
 * It allows you to run Selenium tests on a server without a GUI installed.
 *
 * 1. Download [PhantomJS](http://phantomjs.org/download.html)
 * 2. Run PhantomJS in WebDriver mode: `phantomjs --webdriver=4444`
 * 3. Configure this module (in `acceptance.suite.yml`) by setting url and `phantomjs` as browser:
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: 'http://localhost/'
 *              browser: phantomjs
 * ```
 *
 * Since PhantomJS doesn't give you any visual feedback, it's probably a good idea to install [Codeception\Extension\Recorder](http://codeception.com/extensions#CodeceptionExtensionRecorder) which gives you screenshots of how PhantomJS "sees" your pages.
 *
 * ### Headless Selenium in Docker
 *
 * Docker can ship Selenium Server with all its dependencies and browsers inside a single container.
 * Running tests inside Docker is as easy as pulling [official selenium image](https://github.com/SeleniumHQ/docker-selenium) and starting a container with Chrome:
 *
 * ```
 * docker run --net=host selenium/standalone-chrome
 * ```
 *
 * By using `--net=host` we allow selenium to access local websites.
 *
 * ## Cloud Testing
 *
 * Cloud Testing services can run your WebDriver tests in the cloud.
 * In case you want to test a local site or site behind a firewall
 * you should use a tunnel application provided by a service.
 *
 * ### SauceLabs
 *
 * 1. Create an account at [SauceLabs.com](http://SauceLabs.com) to get your username and access key
 * 2. In the module configuration use the format `username`:`access_key`@ondemand.saucelabs.com' for `host`
 * 3. Configure `platform` under `capabilities` to define the [Operating System](https://docs.saucelabs.com/reference/platforms-configurator/#/)
 * 4. run a tunnel app if your site can't be accessed from Internet
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: http://mysite.com
 *              host: '<username>:<access key>@ondemand.saucelabs.com'
 *              port: 80
 *              browser: chrome
 *              capabilities:
 *                  platform: 'Windows 10'
 * ```
 *
 * ### BrowserStack
 *
 * 1. Create an account at [BrowserStack](https://www.browserstack.com/) to get your username and access key
 * 2. In the module configuration use the format `username`:`access_key`@hub.browserstack.com' for `host`
 * 3. Configure `os` and `os_version` under `capabilities` to define the operating System
 * 4. If your site is available only locally or via VPN you should use a tunnel app. In this case add `browserstack.local` capability and set it to true.
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: http://mysite.com
 *              host: '<username>:<access key>@hub.browserstack.com'
 *              port: 80
 *              browser: chrome
 *              capabilities:
 *                  os: Windows
 *                  os_version: 10
 *                  browserstack.local: true # for local testing
 * ```
 * ### TestingBot
 *
 * 1. Create an account at [TestingBot](https://testingbot.com/) to get your key and secret
 * 2. In the module configuration use the format `key`:`secret`@hub.testingbot.com' for `host`
 * 3. Configure `platform` under `capabilities` to define the [Operating System](https://testingbot.com/support/getting-started/browsers.html)
 * 4. Run [TestingBot Tunnel](https://testingbot.com/support/other/tunnel) if your site can't be accessed from Internet
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: http://mysite.com
 *              host: '<key>:<secret>@hub.testingbot.com'
 *              port: 80
 *              browser: chrome
 *              capabilities:
 *                  platform: Windows 10
 * ```
 *
 * ## Configuration
 *
 * * `url` *required* - Starting URL for your app.
 * * `browser` *required* - Browser to launch.
 * * `host` - Selenium server host (127.0.0.1 by default).
 * * `port` - Selenium server port (4444 by default).
 * * `restart` - Set to `false` (default) to use the same browser window for all tests, or set to `true` to create a new window for each test. In any case, when all tests are finished the browser window is closed.
 * * `start` - Autostart a browser for tests. Can be disabled if browser session is started with `_initializeSession` inside a Helper.
 * * `window_size` - Initial window size. Set to `maximize` or a dimension in the format `640x480`.
 * * `clear_cookies` - Set to false to keep cookies, or set to true (default) to delete all cookies between tests.
 * * `wait` (default: 0 seconds) - Whenever element is required and is not on page, wait for n seconds to find it before fail.
 * * `capabilities` - Sets Selenium [desired capabilities](https://github.com/SeleniumHQ/selenium/wiki/DesiredCapabilities). Should be a key-value array.
 * * `connection_timeout` - timeout for opening a connection to remote selenium server (30 seconds by default).
 * * `request_timeout` - timeout for a request to return something from remote selenium server (30 seconds by default).
 * * `pageload_timeout` - amount of time to wait for a page load to complete before throwing an error (default 0 seconds).
 * * `http_proxy` - sets http proxy server url for testing a remote server.
 * * `http_proxy_port` - sets http proxy server port
 * * `debug_log_entries` - how many selenium entries to print with `debugWebDriverLogs` or on fail (15 by default).
 * * `log_js_errors` - Set to true to include possible JavaScript to HTML report, or set to false (default) to deactivate.
 *
 * Example (`acceptance.suite.yml`)
 *
 * ```yaml
 *     modules:
 *        enabled:
 *           - WebDriver:
 *              url: 'http://localhost/'
 *              browser: firefox
 *              window_size: 1024x768
 *              capabilities:
 *                  unexpectedAlertBehaviour: 'accept'
 *                  firefox_profile: '~/firefox-profiles/codeception-profile.zip.b64'
 * ```
 *
 * ## Usage
 *
 * ### Locating Elements
 *
 * Most methods in this module that operate on a DOM element (e.g. `click`) accept a locator as the first argument,
 * which can be either a string or an array.
 *
 * If the locator is an array, it should have a single element,
 * with the key signifying the locator type (`id`, `name`, `css`, `xpath`, `link`, or `class`)
 * and the value being the locator itself.
 * This is called a "strict" locator.
 * Examples:
 *
 * * `['id' => 'foo']` matches `<div id="foo">`
 * * `['name' => 'foo']` matches `<div name="foo">`
 * * `['css' => 'input[type=input][value=foo]']` matches `<input type="input" value="foo">`
 * * `['xpath' => "//input[@type='submit'][contains(@value, 'foo')]"]` matches `<input type="submit" value="foobar">`
 * * `['link' => 'Click here']` matches `<a href="google.com">Click here</a>`
 * * `['class' => 'foo']` matches `<div class="foo">`
 *
 * Writing good locators can be tricky.
 * The Mozilla team has written an excellent guide titled [Writing reliable locators for Selenium and WebDriver tests](https://blog.mozilla.org/webqa/2013/09/26/writing-reliable-locators-for-selenium-and-webdriver-tests/).
 *
 * If you prefer, you may also pass a string for the locator. This is called a "fuzzy" locator.
 * In this case, Codeception uses a a variety of heuristics (depending on the exact method called) to determine what element you're referring to.
 * For example, here's the heuristic used for the `submitForm` method:
 *
 * 1. Does the locator look like an ID selector (e.g. "#foo")? If so, try to find a form matching that ID.
 * 2. If nothing found, check if locator looks like a CSS selector. If so, run it.
 * 3. If nothing found, check if locator looks like an XPath expression. If so, run it.
 * 4. Throw an `ElementNotFound` exception.
 *
 * Be warned that fuzzy locators can be significantly slower than strict locators.
 * Especially if you use Selenium WebDriver with `wait` (aka implicit wait) option.
 * In the example above if you set `wait` to 5 seconds and use XPath string as fuzzy locator,
 * `submitForm` method will wait for 5 seconds at each step.
 * That means 5 seconds finding the form by ID, another 5 seconds finding by CSS
 * until it finally tries to find the form by XPath).
 * If speed is a concern, it's recommended you stick with explicitly specifying the locator type via the array syntax.
 *
 * ## Public Properties
 *
 * * `webDriver` - instance of `\Facebook\WebDriver\Remote\RemoteWebDriver`. Can be accessed from Helper classes for complex WebDriver interactions.
 *
 * ```php
 * // inside Helper class
 * $this->getModule('WebDriver')->webDriver->getKeyboard()->sendKeys('hello, webdriver');
 * ```

     * Submits the given form on the page, optionally with the given form

     * You don't need to click the 'Submit' button afterwards.

     *
     * You can optionally specify what button's value to include
     * in the request with the last parameter as an alternative to
     * explicitly setting its value in the second parameter, as
     * button values are not otherwise included in the request.
     *
     * Examples:
     *
     * ``` php
     * <?php
     * $I->submitForm('#login', [
     *     'login' => 'davert',
     *     'password' => '123456'

     * $I->submitForm('#login', [
     *     'login' => 'davert',
     *     'password' => '123456'
     * ], 'submitButtonName');
     *
     * ```
     *
     * For example, given this sample "Sign Up" form:
     *
     * ``` html
     * <form action="/sign_up">
     *     Login:
     *     <input type="text" name="user[login]" /><br/>
     *     Password:
     *     <input type="password" name="user[password]" /><br/>
     *     Do you agree to our terms?
     *     <input type="checkbox" name="user[agree]" /><br/>
     *     Select pricing plan:
     *     <select name="plan">
     *         <option value="1">Free</option>
     *         <option value="2" selected="selected">Paid</option>
     *     </select>
     *     <input type="submit" name="submitButton" value="Submit" />
     * </form>
     * ```
     *
     * You could write the following to submit it:
     *
     * ``` php
     * <?php
     * $I->submitForm(
     *     '#userForm',
     *     [
     *         'user[login]' => 'Davert',
     *         'user[password]' => '123456',
     *         'user[agree]' => true
     *     ],
     *     'submitButton'
     * );
     * ```
     * Note that "2" will be the submitted value for the "plan" field, as it is
     * the selected option.
     *
     * Also note that this differs from PhpBrowser, in that
     * ```'user' => [ 'login' => 'Davert' ]``` is not supported at the moment.
     * Named array keys *must* be included in the name as above.
     *
     * Pair this with seeInFormFields for quick testing magic.
     *
     * ``` php
     * <?php
     * $form = [
     *      'field1' => 'value',
     *      'field2' => 'another value',
     *      'checkbox1' => true,
     *      // ...

     * // $I->amOnPage('/path/to/form-page') may be needed
     * $I->seeInFormFields('//form[@id=my-form]', $form);
     * ?>
     * ```
     *
     * Parameter values must be set to arrays for multiple input fields
     * of the same name, or multi-select combo boxes.  For checkboxes,
     * either the string value can be used, or boolean values which will
     * be replaced by the checkbox's value in the DOM.

     * Mixing string and boolean values for a checkbox's value is not supported
     * and may produce unexpected results.
     *
     * Field names ending in "[]" must be passed without the trailing square
     * bracket characters, and must contain an array for its value.  This allows
     * submitting multiple values with the same name, consider:
     *
     * ```php
     * $I->submitForm('#my-form', [
     *     'field[]' => 'value',
     *     'field[]' => 'another value', // 'field[]' is already a defined key
     * ]);
     * ```
     *
     * The solution is to pass an array value:
     *
     * ```php
     * // this way both values are submitted
     * $I->submitForm('#my-form', [
     *     'field' => [
     *         'value',
     *         'another value',
     *     ]
     * ]);
     * ```
     *
     * The `$button` parameter can be either a string, an array or an instance
     * of Facebook\WebDriver\WebDriverBy. When it is a string, the
     * button will be found by its "name" attribute. If $button is an
     * array then it will be treated as a strict selector and a WebDriverBy
     * will be used verbatim.
     *
     * For example, given the following HTML:
     *
     * ``` html
     * <input type="submit" name="submitButton" value="Submit" />
     * ```
     *
     * `$button` could be any one of the following:
     *   - 'submitButton'
     *   - ['name' => 'submitButton']
     *   - WebDriverBy::name('submitButton')
     *

    /**
     * Waits for element and runs a sequence of actions inside its context.
     * Actions can be defined with array, callback, or `Codeception\Util\ActionSequence` instance.
     *
     * Actions as array are recommended for simple to combine "waitForElement" with assertions;
     * `waitForElement($el)` and `see('text', $el)` can be simplified to:
     *
     * ```php
     * <?php
     * $I->performOn($el, ['see' => 'text']);
     * ```
     *
     * List of actions can be pragmatically build using `Codeception\Util\ActionSequence`:
     *
     * ```php
     * <?php
     * $I->performOn('.model', ActionSequence::build()
     *     ->see('Warning')
     *     ->see('Are you sure you want to delete this?')
     *     ->click('Yes')
     * );
     * ```
     *
     * Actions executed from array or ActionSequence will print debug output for actions, and adds an action name to
     * exception on failure.
     *
     * Whenever you need to define more actions a callback can be used. A WebDriver module is passed for argument:
     *
     * ```php
     * <?php
     * $I->performOn('.rememberMe', function (WebDriver $I) {
     *      $I->see('Remember me next time');
     *      $I->seeElement('#LoginForm_rememberMe');
     *      $I->dontSee('Login');
     * });
     * ```
     *
     * In 3rd argument you can set number a seconds to wait for element to appear
     *
     * @param $element
     * @param $actions
     * @param int $timeout
     */
