WebDriver

Installation

composer require --dev codeception/module-webdriver

Description

Run tests in real browsers using the W3C WebDriver protocol. There are multiple ways of running browser tests using WebDriver:

Selenium (Recommended)

• Java is required
• NodeJS is required

The fastest way to get started is to Install and launch Selenium using selenium-standalone NodeJS package.

Launch selenium standalone in separate console window:

selenium-standalone start

Update configuration in Acceptance.suite.yml:

modules:
   enabled:
      - WebDriver:
         url: 'https://localhost/'
         browser: chrome # 'chrome' or 'firefox'

Headless Chrome Browser

To enable headless mode (launch tests without showing a window) for Chrome browser using Selenium use this config in Acceptance.suite.yml:

modules:
   enabled:
      - WebDriver:
         url: 'https://localhost/'
         browser: chrome
         capabilities:
            goog:chromeOptions:
               args: ["--headless"]

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 and starting a container with Chrome:

docker run --net=host --shm-size 2g selenium/standalone-chrome

By using --net=host allow Selenium to access local websites.

Local Chrome and/or Firefox

Tests can be executed directly through ChromeDriver or GeckoDriver (for Firefox). Consider using this option if you don’t plan to use Selenium.

ChromeDriver

• Download and install ChromeDriver
• Launch ChromeDriver in a separate console window: chromedriver --url-base=/wd/hub.

Configuration in Acceptance.suite.yml:

modules:
   enabled:
      - WebDriver:
         browser: chrome
         url: 'https://localhost/'
         window_size: 2000x1000
         port: 9515
         capabilities:
             goog:chromeOptions:
                 args: ["--headless"] # Run Chrome in headless mode
                 prefs:
                     download.default_directory: "..."

See here for additional Chrome options

GeckoDriver

• GeckoDriver must be installed
• Start GeckoDriver in a separate console window: geckodriver.

Configuration in Acceptance.suite.yml:

modules:
   enabled:
      - WebDriver:
         browser: firefox
         url: 'https://localhost/'
         window_size: 2000x1000
         path: ''
         capabilities:
             acceptInsecureCerts: true # allow self-signed certificates
             moz:firefoxOptions:
                 args: ["-headless"] # Run Firefox in headless mode
                 prefs:
                     intl.accept_languages: "de-AT" # Set HTTP-Header `Accept-Language: de-AT` for requests

See here for Firefox capabilities

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 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 platformName under capabilities to define the Operating System
4. run a tunnel app if your site can’t be accessed from Internet

    modules:
       enabled:
          - WebDriver:
             url: https://mysite.com
             host: '<username>:<access key>@ondemand.saucelabs.com'
             port: 80
             browser: chrome
             capabilities:
                 platformName: 'Windows 10'

BrowserStack

1. Create an account at BrowserStack 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.

 modules:
     enabled:
         - WebDriver:
             url: https://mysite.com
             host: '<username>:<access key>@hub.browserstack.com'

             browser: chrome
             capabilities:
                 bstack:options:
                     os: Windows
                     osVersion: 10
                     local: true # for local testing

LambdaTest

1. Create an account at LambdaTest to get your username and access key
2. In the module configuration use the format username:access key@hub.lambdatest.com’ for host
3. Configure platformName, ‘browserVersion’, and ‘browserName’ under LT:Options to define test environments.
4. If your website is available only locally or via VPN you should use LambdaTest tunnel. In this case, you can add capability “tunnel”:true;.

 modules:
     enabled:
           - WebDriver:
               url: "https://openclassrooms.com"
               host: 'hub.lambdatest.com'
               port: 80
               browser: 'Chrome'
               capabilities:
                   LT:Options:
                   platformName: 'Windows 10'
                   browserVersion: 'latest-5'
                   browserName: 'Chrome'
                   tunnel: true #for Local testing

TestingBot

1. Create an account at TestingBot to get your key and secret

             platformName: Windows 10

Configuration

• url required - Base URL for your app (amOnPage opens URLs relative to this setting).
• 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. 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
• ssl_proxy - sets ssl(https) proxy server url for testing a remote server.
• ssl_proxy_port - sets ssl(https) proxy server port
• debug_log_entries - how many selenium entries to print with debugWebDriverLogs or on fail (0 by default).
• log_js_errors - Set to true to include possible JavaScript to HTML report, or set to false (default) to deactivate. This will only work if debug_log_entries is set and its value is > 0. Also this will display JS errors as comments only if test fails.
• webdriver_proxy - sets http proxy to tunnel requests to the remote Selenium WebDriver through
• webdriver_proxy_port - sets http proxy server port to tunnel requests to the remote Selenium WebDriver through

Example (Acceptance.suite.yml)

modules:
   enabled:
      - WebDriver:
         url: 'https://localhost/'
         browser: firefox
         window_size: 1024x768
         capabilities:
             unhandledPromptBehaviour: 'accept'
             moz:firefoxOptions:
                 profile: '~/firefox-profiles/codeception-profile.zip.b64'

Loading Parts from other Modules

While all Codeception modules are designed to work stand-alone, it’s still possible to load several modules at once. To use e.g. the Asserts module in your acceptance tests, just load it like this in your acceptance.suite.yml:

modules:
    enabled:
        - WebDriver
        - Asserts

However, when loading a framework module (e.g. Symfony) like this, it would lead to a conflict: When you call $I->amOnPage(), Codeception wouldn’t know if you want to access the page using WebDriver’s amOnPage(), or Symfony’s amOnPage(). That’s why possibly conflicting modules are separated into “parts”. Here’s how to load just the “services” part from e.g. Symfony:

modules:
    enabled:
        - WebDriver
        - Symfony:
            part: services

To find out which parts each module has, look at the “Parts” header on the module’s page.

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.

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.

Get Scenario Metadata

You can inject \Codeception\Scenario into your test to get information about the current configuration:

use Codeception\Scenario;
public function myTest(AcceptanceTester $I, Scenario $scenario)
{
    if ('firefox' === $scenario->current('browser')) {
        // ...
    }
}

See Get Scenario Metadata for more information on $scenario.

Public Properties

• webDriver - instance of \Facebook\WebDriver\Remote\RemoteWebDriver. Can be accessed from Helper classes for complex WebDriver interactions.

// inside Helper class
$this->getModule('WebDriver')->webDriver->getKeyboard()->sendKeys('hello, webdriver');

Actions

_backupSession

hidden API method, expected to be used from Helper classes

• api
• return \Facebook\WebDriver\WebDriver

Returns current WebDriver session for saving

_capabilities

hidden API method, expected to be used from Helper classes

• api
• param \Closure $capabilityFunction
• return void

Change capabilities of WebDriver. Should be executed before starting a new browser session.

This method expects a function to be passed which returns array or WebDriver Desired Capabilities object. Additional Chrome options (like adding extensions) can be passed as well.

<?php // in helper
public function _before(TestInterface $test)
{
    $this->getModule('WebDriver')->_capabilities(function($currentCapabilities) {
        // or new \Facebook\WebDriver\Remote\DesiredCapabilities();
        return \Facebook\WebDriver\Remote\DesiredCapabilities::firefox();
    });
}

to make this work load \Helper\Acceptance before WebDriver in acceptance.suite.yml:

modules:
    enabled:
        - \Helper\Acceptance
        - WebDriver

For instance, BrowserStack cloud service may require a test name to be set in capabilities. This is how it can be done via _capabilities method from Helper\Acceptance:

<?php
// inside Helper\Acceptance
public function _before(TestInterface $test)
{
     $name = $test->getMetadata()->getName();
     $this->getModule('WebDriver')->_capabilities(function($currentCapabilities) use ($name) {
         $currentCapabilities['name'] = $name;
         return $currentCapabilities;
     });
}

In this case, please ensure that \Helper\Acceptance is loaded before WebDriver so new capabilities could be applied.

_closeSession

hidden API method, expected to be used from Helper classes

• api
• param RemoteWebDriver|null $webDriver a specific webdriver session instance
• return void

Manually closes current WebDriver session.

<?php
$this->getModule('WebDriver')->_closeSession();
// close a specific session
$webDriver = $this->getModule('WebDriver')->webDriver;
$this->getModule('WebDriver')->_closeSession($webDriver);

_findClickable

Use it in Helpers or GroupObject or Extension classes:

<?php
$module = $this->getModule('WebDriver');
$page = $module->webDriver;
// search a link or button on a page
$el = $module->_findClickable($page, 'Click Me');
// search a link or button within an element
$topBar = $module->_findElements('.top-bar')[0];
$el = $module->_findClickable($topBar, 'Click Me');

_findElements

hidden API method, expected to be used from Helper classes

• api
• param $locator
• return array

Locates element using available Codeception locator types:

• XPath
• CSS
• Strict Locator

Use it in Helpers or GroupObject or Extension classes:

<?php
$els = $this->getModule('WebDriver')->_findElements('.items');
$els = $this->getModule('WebDriver')->_findElements(['name' => 'username']);
$editLinks = $this->getModule('WebDriver')->_findElements(['link' => 'Edit']);
// now you can iterate over $editLinks and check that all them have valid hrefs

WebDriver module returns Facebook\WebDriver\Remote\RemoteWebElement instances PhpBrowser and Framework modules return Symfony\Component\DomCrawler\Crawler instances

If a fuzzy locator is given, the page will be searched for a button, link, or image matching the locator string. For buttons, the “value” attribute, “name” attribute, and inner text are searched. For links, the link text is searched. For images, the “alt” attribute and inner text of any parent links are searched.

The second parameter is a context (CSS or XPath locator) to narrow the search.

Note that if the locator matches a button of type submit, the form will be submitted.

<?php

$I->dontSee('Sign Up','h1');                  // I can suppose it's not a signup page
$I->dontSee('Sign Up','//body/h1');           // with XPath
$I->dontSee('Sign Up', ['css' => 'body h1']); // with strict CSS locator

Note that the search is done after stripping all HTML tags from the body, so $I->dontSee('strong') will fail on strings like:

• <p>I am Stronger than thou</p>
• <script>document.createElement('strong');</script>

But will ignore strings like:

• <strong>Home</strong>
• <div class="strong">Home</strong>
• <!-- strong -->

For checking the raw source code, use seeInSource().

dontSeeCheckboxIsChecked

     'input1' => 'non-existent value',
     'input2' => 'other non-existent value',
]);

To check that an element hasn’t been assigned any one of many values, an array can be passed as the value:

<?php
$I->dontSeeInFormFields('.form-class', [
     'fieldName' => [
         'This value shouldn\'t be set',
         'And this value shouldn\'t be set',
     ],
]);

Additionally, checkbox values can be checked with a boolean.

<?php
$I->dontSeeInFormFields('#form-id', [

$I->executeAsyncJS('setTimeout(arguments[1], arguments[0])', [$seconds]);

executeInSelenium

• param Closure $function
• return mixed

Low-level API method.

If Codeception commands are not enough, this allows you to use Selenium WebDriver methods directly:

$I->executeInSelenium(function(\Facebook\WebDriver\Remote\RemoteWebDriver $webdriver) {
  $webdriver->get('https://google.com');
});

This runs in the context of the RemoteWebDriver class. Try not to use this command on a regular basis. If Codeception lacks a feature you need, please implement it and submit a patch.

$I->grabAttributeFrom('#tooltip', 'title');

grabCookie

• param $cookie
• param array $params
• return mixed

Grabs a cookie value.

You can set additional cookie params like domain, path in array passed as last argument. If the cookie is set by an ajax request (XMLHttpRequest), there might be some delay caused by the browser, so try $I->wait(0.1).

If a fuzzy locator is used, the field is found by field name, CSS, and XPath.

<?php
$name = $I->grabValueFrom('Name');
$name = $I->grabValueFrom('input[name=username]');
$name = $I->grabValueFrom('descendant-or-self::form/descendant::input[@name = 'username']');
$name = $I->grabValueFrom(['name' => 'username']);

Maximizes the current window.

moveBack

• return void

Moves back in history.

• param null|string|array|WebDriverBy $cssOrXPath css or xpath of the web element
• param ?int $offsetX
• param ?int $offsetY
• throws ElementNotFound
• return void

<?php
$I->moveMouseOver(['css' => '.checkout']);
$I->moveMouseOver(null, 20, 50);
$I->moveMouseOver(['css' => '.checkout'], 20, 50);

openNewTab

• return void

Opens a new browser tab and switches to it.

<?php
$I->openNewTab();

The tab is opened with JavaScript’s window.open(), which means:

• Some ad-blockers might restrict it.
• The sessionStorage is copied to the new tab (contrary to a tab that was manually opened by the user)

performOn

• param string|array|WebDriverBy $element
• param callable|array|\Codeception\Util\ActionSequence $actions
• param int $timeout
• return void

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
$I->performOn($el, ['see' => 'text']);

List of actions can be pragmatically build using Codeception\Util\ActionSequence:

<?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
$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 string|array|WebDriverBy $element
• param string|list<string> $chars Can be char or array with modifier. You can provide several chars.
• throws ElementNotFound
• return void

Presses the given key on the given element.

To specify a character and modifier (e.g. Ctrl, Alt, Shift, Meta), pass an array for $char with the modifier as the first element and the character as the second. For special keys, use the constants from Facebook\WebDriver\WebDriverKeys.

<?php
// <input id="page" value="old">
$I->pressKey('#page', 'a'); // => olda
$I->pressKey('#page', ['ctrl', 'a'],'new'); // => new
$I->pressKey('#page', ['shift', '111'], '1', 'x'); // => old!!!1x
$I->pressKey('descendant-or-self::*[@id='page']', 'u'); // => oldu
$I->pressKey('#name', ['ctrl', 'a'], \Facebook\WebDriver\WebDriverKeys::DELETE); // =>''

• param $cookie
• param array $params
• param bool $showDebug
• return mixed|void

Unsets cookie with the given name.

You can set additional cookie params like domain, path in array passed as last argument.

• param int $width
• param int $height
• return void

Resize the current window.

<?php
$I->resizeWindow(800, 600);

saveSessionSnapshot

• param $name
• return mixed

Saves current cookies into named snapshot in order to restore them in other tests This is useful to save session state between tests.

For example, if user needs log in to site for each test this scenario can be executed once while other tests can just restore saved cookies.

<?php
// inside AcceptanceTester class:
public function login()
{
     // if snapshot exists - skipping login
     if ($I->loadSessionSnapshot('login')) return;
     // logging in
     $I->amOnPage('/login');
     $I->fillField('name', 'jon');
     $I->fillField('password', '123345');
     $I->click('Login');
     // saving snapshot
     $I->saveSessionSnapshot('login');
}

scrollTo

• param string|array|WebDriverBy $selector
• param ?int $offsetX
• param ?int $offsetY
• return void

Move to the middle of the given element matched by the given locator.

Extra shift, calculated from the top-left corner of the element, can be set by passing $offsetX and $offsetY parameters.

<?php
$I->scrollTo(['css' => '.checkout'], 20, 50);

see

• param $text
• param array|string $selector optional
• return void

Checks that the current page contains the given string (case insensitive).

You can specify a specific HTML element (via CSS or XPath) as the second parameter to only search within that element.

<?php
$I->see('Logout');                        // I can suppose user is logged in
$I->see('Sign Up', 'h1');                 // I can suppose it's a signup page
$I->see('Sign Up', '//body/h1');          // with XPath
$I->see('Sign Up', ['css' => 'body h1']); // with strict CSS locator

Note that the search is done after stripping all HTML tags from the body, so $I->see('strong') will return true for strings like:

• <p>I am Stronger than thou</p>
• <script>document.createElement('strong');</script>

But will not be true for strings like:

• <strong>Home</strong>
• <div class="strong">Home</strong>
• <!-- strong -->

For checking the raw source code, use seeInSource().

$I->seeElement('//form/input[1]');
$I->seeElement('input', ['name' => 'login']);
$I->seeElement('input', ['value' => '123456']);

     'input1' => 'value',
     'input2' => 'other value',
]);

For multi-select elements, or to check values of multiple elements with the same name, an array may be passed:

<?php
$I->seeInFormFields('.form-class', [
     'multiselect' => [
         'value1',
         'value2',
     ],
     'checkbox[]' => [
         'a checked value',
         'another checked value',
     ],
]);

$I->seeInFormFields('#form-id', [
     'checkbox1' => true,        // passes if checked
     'checkbox2' => false,       // passes if unchecked
]);

Pair this with submitForm for quick testing magic.

<?php
$form = [
     'field1' => 'value',
     'field2' => 'another value',
     'checkbox1' => true,
     // ...
];
$I->submitForm('//form[@id=my-form]', string $form, 'submitButton');
// $I->amOnPage('/path/to/form-page') may be needed
$I->seeInFormFields('//form[@id=my-form]', string $form);

Provide an array for the second argument to select multiple options:

<?php
$I->selectOption('Which OS do you use?', ['Windows', 'Linux']);

Or provide an associative array for the second argument to specifically define which selection method should be used:

<?php
$I->selectOption('Which OS do you use?', ['text' => 'Windows']); // Only search by text 'Windows'
$I->selectOption('Which OS do you use?', ['value' => 'windows']); // Only search by value 'windows'

setCookie

• param $name
• param $value
• param array $params
• param $showDebug
• return mixed|void

You can set additional cookie params like domain, path, expires, secure in array passed as last argument.

<?php
$I->setCookie('PHPSESSID', 'el4ukv0kqbvoirg7nkp4dncpk3');

submitForm

• param string|array|WebDriverBy $selector
• param array $params
• param string|array|WebDriverBy|null $button
• return void

Submits the given form on the page, optionally with the given form values. Give the form fields values as an array. Note that hidden fields can’t be accessed.

Skipped fields will be filled by their values from the page. You don’t need to click the ‘Submit’ button afterwards. This command itself triggers the request to form’s action.

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
$I->submitForm('#login', [
    'login' => 'davert',
    'password' => '123456'
]);
// or
$I->submitForm('#login', [
    'login' => 'davert',
    'password' => '123456'
], 'submitButtonName');

For example, given this sample “Sign Up” form:

<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
$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
$form = [
     'field1' => 'value',
     'field2' => 'another value',
     'checkbox1' => true,
     // ...
];
$I->submitForm('//form[@id=my-form]', $form, 'submitButton');
// $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.

<?php
$I->submitForm('#my-form', [
     'field1' => 'value',
     'checkbox' => [
         'value of first checkbox',
         'value of second checkbox',
     ],
     'otherCheckboxes' => [
         true,
         false,
         false,
     ],
     'multiselect' => [
         'first option value',
         'second option value',
     ]
]);

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:

$I->submitForm('#my-form', [
    'field[]' => 'value',
    'field[]' => 'another value', // 'field[]' is already a defined key
]);

The solution is to pass an array value:

// 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:

<input type="submit" name="submitButton" value="Submit">

$button could be any one of the following:

• ‘submitButton’
• [‘name’ => ‘submitButton’]
• WebDriverBy::name(‘submitButton’)

switchToFrame

• param string|null $locator (name, CSS or XPath)
• return void

Switch to another frame on the page.

Example:

<frame name="another_frame" id="fr1" src="https://example.com">

<?php
# switch to frame by name
$I->switchToFrame("another_frame");
# switch to frame by CSS or XPath
$I->switchToFrame("#fr1");
# switch to parent page
$I->switchToFrame();

switchToIFrame

• param string|null $locator (name, CSS or XPath)
• return void

Switch to another iframe on the page.

Example:

<iframe name="another_frame" id="fr1" src="https://example.com">

<?php
# switch to iframe by name
$I->switchToIFrame("another_frame");
# switch to iframe by CSS or XPath
$I->switchToIFrame("#fr1");
# switch to parent page
$I->switchToIFrame();

switchToNextTab

• param int $offset
• return void

Switches to next browser tab.

An offset can be specified.

<?php
// switch to next tab
$I->switchToNextTab();
// switch to 2nd next tab
$I->switchToNextTab(2);

switchToPreviousTab

• param int $offset
• return void

Switches to previous browser tab.

An offset can be specified.

<?php
// switch to previous tab
$I->switchToPreviousTab();
// switch to 2nd previous tab
$I->switchToPreviousTab(2);

switchToWindow

• param ?string $name
• return void

Switch to another window identified by name.

The window can only be identified by name. If the $name parameter is blank, the parent window will be used.

Example:

<input type="button" value="Open window" onclick="window.open('https://example.com', 'another_window')">

<?php
$I->click("Open window");
# switch to another window
$I->switchToWindow("another_window");
# switch to parent window
$I->switchToWindow();

If the window has no name, match it by switching to next active tab using switchToNextTab method.

Or use native Selenium functions to get access to all opened windows:

<?php
$I->executeInSelenium(function (\Facebook\WebDriver\Remote\RemoteWebDriver $webdriver) {
     $handles=$webdriver->getWindowHandles();
     $last_window = end($handles);
     $webdriver->switchTo()->window($last_window);
});

type

• param string $text
• param int $delay [sec]
• return void

With a second parameter you can specify delay between key presses.

<?php
// activate input element
$I->click('#input');
// type text in active element
$I->type('Hello world');
// type text with a 1sec delay between chars
$I->type('Hello World', 1);

This might be useful when you an input reacts to typing and you need to slow it down to emulate human behavior. For instance, this is how Credit Card fields can be filled in.
