php-webdriver – Selenium WebDriver bindings for PHP

Description

Php-webdriver library is PHP language binding for Selenium WebDriver, which allows you to control web browsers from PHP.

This library is compatible with Selenium server version 2.x, 3.x and 4.x.

The library supports JsonWireProtocol and also implements experimental support of W3C WebDriver. The W3C WebDriver support is not yet full-featured, however it should allow to control Firefox via Geckodriver and new versions of Chrome and Chromedriver with just a slight limitations.

The concepts of this library are very similar to the "official" Java, .NET, Python and Ruby bindings from the Selenium project.

Installation

Installation is possible using Composer.

If you don't already use Composer, you can download the composer.phar binary:

curl -sS https://getcomposer.org/installer | php

Then install the library:

php composer.phar require php-webdriver/webdriver

Upgrade from version <1.8.0

Starting from version 1.8.0, the project has been renamed from facebook/php-webdriver to php-webdriver/webdriver.

In order to receive the new version and future updates, you need to rename it in your composer.json:

"require": {
-    "facebook/webdriver": "(version you use)",
+    "php-webdriver/webdriver": "(version you use)",
}

and run composer update.

Getting started

1. Start server (aka. remote end)

To control a browser, you need to start a remote end (server), which will listen to the commands sent from this library and will execute them in the respective browser.

This could be Selenium standalone server, but for local development, you can send them directly to so-called "browser driver" like Chromedriver or Geckodriver.

a) Chromedriver

📙 Below you will find a simple example. Make sure to read our wiki for more information on Chrome/Chromedriver.

Install the latest Chrome and Chromedriver. Make sure to have a compatible version of Chromedriver and Chrome!

Run chromedriver binary, you can pass port argument, so that it listens on port 4444:

chromedriver --port=4444

b) Geckodriver

Install the latest Firefox and Geckodriver. Make sure to have a compatible version of Geckodriver and Firefox!

Run geckodriver binary (it start to listen on port 4444 by default):

geckodriver

c) Selenium standalone server

Selenium server can be useful when you need to execute multiple tests at once, when you run tests in several different browsers (like on your CI server), or when you need to distribute tests amongst several machines in grid mode (where one Selenium server acts as a hub, and others connect to it as nodes).

Selenium server then act like a proxy and takes care of distributing commands to the respective nodes.

The latest version can be found on the Selenium download page.

📙 You can find further Selenium server information in our wiki.

d) Docker

Selenium server could also be started inside Docker container - see docker-selenium project.

2. Create a Browser Session

When creating a browser session, be sure to pass the url of your running server.

For example:

// Chromedriver (if started using --port=4444 as above)
$serverUrl = 'http://localhost:4444';
// Geckodriver
$serverUrl = 'http://localhost:4444';
// selenium-server-standalone-#.jar (version 2.x or 3.x)
$serverUrl = 'http://localhost:4444/wd/hub';
// selenium-server-standalone-#.jar (version 4.x)
$serverUrl = 'http://localhost:4444';

Now you can start browser of your choice:

use Facebook\WebDriver\Remote\RemoteWebDriver;

// Chrome
$driver = RemoteWebDriver::create($serverUrl, DesiredCapabilities::chrome());
// Firefox
$driver = RemoteWebDriver::create($serverUrl, DesiredCapabilities::firefox());
// Microsoft Edge
$driver = RemoteWebDriver::create($serverUrl, DesiredCapabilities::microsoftEdge());

3. Customize Desired Capabilities

Desired capabilities define properties of the browser you are about to start.

They can be customized:

use Facebook\WebDriver\Remote\DesiredCapabilities;

$desiredCapabilities = DesiredCapabilities::firefox();

// Disable accepting SSL certificates
$desiredCapabilities->setCapability('acceptSslCerts', false);

// Run headless firefox
$desiredCapabilities->setCapability('moz:firefoxOptions', ['args' => ['-headless']]);

$driver = RemoteWebDriver::create($serverUrl, $desiredCapabilities);

Capabilities can also be used to 📙 configure a proxy server which the browser should use. To configure Chrome capabilities, you may use 📙 ChromeOptions.

See legacy JsonWire protocol documentation or W3C WebDriver specification for more details.

4. Control your browser

// Go to URL
$driver->get('https://en.wikipedia.org/wiki/Selenium_(software)');

// Find search element by its id, write 'PHP' inside and submit
$driver->findElement(WebDriverBy::id('searchInput')) // find search input element
    ->sendKeys('PHP') // fill the search box
    ->submit(); // submit the whole form

// Find element of 'History' item in menu by its css selector
$historyButton = $driver->findElement(
    WebDriverBy::cssSelector('#ca-history a')
);
// Read text of the element and print it to output
echo 'About to click to a button with text: ' . $historyButton->getText();

// Click the element to navigate to revision history page
$historyButton->click();

More information

Some basic usage example is provided in example.php file.

How-tos are provided right here in 📙 our GitHub wiki.

Testing framework integration

To take advantage of automatized testing you may want to integrate php-webdriver to your testing framework. There are some projects already providing this:

Symfony Panther uses php-webdriver and integrates with PHPUnit using PantherTestCase
Laravel Dusk is another project using php-webdriver, could be used for testing via DuskTestCase
Steward integrates php-webdriver directly to PHPUnit, and provides parallelization
Codeception testing framework provides BDD-layer on top of php-webdriver in its WebDriver module
You can also check out this blogpost + demo project, describing simple PHPUnit integration
