PHP WebDriver is a tool that can be used for automated testing. It can simulate user operations on the browser, such as filling in forms, clicking buttons, etc. PHP WebDriver is a library of the PHP language. It is based on Selenium WebDriver and communicates with the browser through the PHP client to implement automated execution of test scenarios. In this article, we will build an automated test case from scratch using PHP WebDriver.

Step 1: Install PHP WebDriver

First, we need to install PHP WebDriver. The GitHub address of PHP WebDriver is https://github.com/php-webdriver/php-webdriver. This library has been published on packagist, so it can be installed using composer:

$ composer require facebook/php-webdriver

Copy after login

This will install all the dependencies of PHP WebDriver.

Step 2: Create a test case

Next we need to create a test case. We will use a simple login page as a test case. The code is as follows:

<!DOCTYPE html>
<html>
<head>
    <title>Login Page</title>
</head>
<body>
    <form action="" method="post">
        <label>Username:</label>
        <input type="text" name="username"/><br/><br/>
        <label>Password:</label>
        <input type="password" name="password"/><br/><br/>
        <input type="submit" value="Login"/>
    </form>
</body>
</html>

Copy after login

In this example, we have an HTML form that contains username and password input boxes, and a login button. We will use PHP WebDriver to simulate the user entering their username and password into this form and then clicking the login button.

Step 3: Write test code

Now we will write test code to simulate user operations and verify whether the login function is normal. The PHP WebDriver code is as follows:

<?php
require_once('vendor/autoload.php');

use FacebookWebDriverRemoteRemoteWebDriver;
use FacebookWebDriverWebDriverBy;

// 配置
$host = 'http://localhost:4444/wd/hub';
$capabilities = ['browserName' => 'chrome'];
$driver = RemoteWebDriver::create($host, $capabilities);

// 访问页面
$driver->get('http://localhost/login.html');

// 填写用户名和密码
$username = $driver->findElement(WebDriverBy::name('username'));
$username->sendKeys('user@example.com');

$password = $driver->findElement(WebDriverBy::name('password'));
$password->sendKeys('password');

// 单击登录按钮
$loginButton = $driver->findElement(WebDriverBy::xpath('//input[@type="submit"]'));
$loginButton->click();

// 验证登录
$welcomeMessage = $driver->findElement(WebDriverBy::tagName('h1'))->getText();
assert($welcomeMessage == 'Welcome to your account');

// 关闭浏览器
$driver->quit();

Copy after login

First, we need to import PHP WebDriver into the test code. We then configure the browser type and address requested from the remote WebDriver service. In this example, we use the Chrome browser. Next, we visit the test case page and simulate the user entering their username and password in the login form and clicking the login button. Finally, we use an assertion to verify that the login was successful and close the browser.

Step 4: Run the test

We can now run the test script and view the results. To run tests, you can use the PHPUnit testing framework. In the command line, go to the directory where the test file is located and run the following command:

$ vendor/bin/phpunit loginTest.php

Copy after login

If the test is successful, we will see PHPUnit output a green "OK" result.

Building automated tests helps improve the quality and efficiency of testing and ensures that potential code issues are detected during development and deployment. By using PHP WebDriver, we can easily create automated tests and verify that functionality works as expected by simulating user actions. This article provides an entry-level example that I hope will be helpful to you.
