Performance testing example using PHP WebDriver

With the rapid development of Internet technology, people have higher and higher requirements for products, especially for product performance requirements. Therefore, performance testing is very important. In performance testing, there are many commonly used tools, among which PHP WebDriver is a commonly used one.

This article will introduce how to use PHP WebDriver to implement a simple performance testing example. First, we need to understand what PHP WebDriver is.

1. What is PHP WebDriver

PHP WebDriver is a library based on PHP language and Selenium WebDriver protocol. It uses PHP language to operate WebDriver API to automate browsers (including Google Chrome, Firefox, etc.) device).

Compared with other performance testing tools, the advantage of using PHP WebDriver is that it can realize browser simulation, JS script execution, AJAX request and other operations, which is closer to the usage scenario of real users, so it can be more accurate Test the performance of the website.

2. Use PHP WebDriver for performance testing

Next, we will take the performance test of a website as an example to show how to use PHP WebDriver for performance testing.

1. Install PHP WebDriver

First, we need to install PHP WebDriver through Composer. Just enter the following command on the command line:

composer require facebook/webdriver

2. Prepare the test case

We take the Baidu homepage as an example to test the loading time of the website. The specific test code is as follows:

use FacebookWebDriverRemoteDesiredCapabilities;
use FacebookWebDriverRemoteRemoteWebDriver;

// Specify the WebDriver server connection credentials.
$host = 'http://localhost:9515'; // this is the default
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities);

// 记录开始时间
$start = microtime(true);

// 测试百度首页的加载时间
$driver->get('https://www.baidu.com');

// 记录结束时间
$end = microtime(true);

// 输出加载时间
echo "Loaded in " . ($end - $start) . " seconds.";

// 关闭浏览器
$driver->quit();

In this test case, we first record the test start time, then use the $driver->get() method to access the Baidu homepage, then record the test end time, and finally Output loading time.

3. Run the test case

Next, we execute the test case. Enter the following command on the command line:

php test.php

where test.php is the file name of the test case.

After the execution is completed, we can see the output result, which is the loading time.

Through the above steps, we can use PHP WebDriver to test the performance of a website. Of course, this is just a simple example, in fact we can write more complex test cases to test the performance of the website. At the same time, we can also use PHP WebDriver to solve other problems, such as automated testing.

Summary

This article introduces how to use PHP WebDriver to implement a simple performance test example. Compared with other performance testing tools, the advantage of using PHP WebDriver is that it can realize browser simulation, JS script execution, AJAX requests and other operations, which is closer to the usage scenario of real users, so it can more accurately test the performance of the website.
