PHP with Selenium: Tutorial to Run Your First Test on LambdaTest

---

In this topic, you will learn how to configure and run your PHP automation testing scripts on LambdaTest Selenium cloud platform.

Objective

---

By the end of this topic, you will be able to:

1. Set up an environment for testing your locally hosted web pages using PHP automation testing.
2. Understand and configure the core capabilities required for your Selenium test suite.
3. Test your locally hosted pages on LambdaTest platform.
4. Explore advanced features of LambdaTest.

Note: All the code samples in this documentation can be found in the Behat LambdaTest Repository on GitHub. You can either download or clone the repository to quickly run your tests.

Prerequisites For Running PHP Selenium Scripts

---

Before you begin automation testing with Selenium, you would need to:

• Make sure that you have the latest PHP installed on your system. You can download and install PHP using following commands in the terminal:

  • MacOS: Previous versions of MacOS have PHP installed by default. But for the latest MacOS versions starting with Monterey, PHP has to be downloaded and installed manually by using below commands:

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  brew install php
  • Windows:

For Windows, you can download PHP from PHP for Windows website. Also, refer to this documentation for ensuring the accessibility of PHP through Command Prompt(cmd).

• Download composer in the project directory (Linux/MacOS, Windows).

  Note: To use the composer command directly, it either should have been downloaded in the project directory or should be accessible globally which can be done by the command below:

  mv composer.phar /usr/local/bin/composer

Installing Selenium Dependencies and Tutorial Repo

Step 1: Clone the LambdaTest’s Php-Selenium repository and navigate to the code directory as shown below:

git clone https://github.com/LambdaTest-sample-test-frameworks/Php-Selenium
cd Php-Selenium

Step 2: Install the composer dependencies in the current project directory using the command below:

composer install

Setting Up Your Authentication

Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest Selenium Grid. You can obtain these credentials from the LambdaTest Automation Dashboard or through LambdaTest Profile.

Step 3: Set LambdaTest Username and Access Key in environment variables.

• For Linux/macOS:

export LT_USERNAME="YOUR_USERNAME" export LT_ACCESS_KEY="YOUR ACCESS KEY"

• For Windows:

set LT_USERNAME="YOUR_USERNAME" set LT_ACCESS_KEY="YOUR ACCESS KEY"

Run Your First Test

Sample Test with PHP

Let's check the sample test script LambdaTest.php.

<?php

require 'vendor/autoload.php';

$GLOBALS['LT_USERNAME'] = getenv('LT_USERNAME');

$GLOBALS['LT_ACCESS_KEY'] = getenv('LT_ACCESS_KEY');

$GLOBALS['LT_BROWSER'] = getenv('LT_BROWSER');
if(!$GLOBALS['LT_BROWSER']) $GLOBALS['LT_BROWSER'] = "chrome";

$GLOBALS['LT_BROWSER_VERSION'] = getenv('LT_BROWSER_VERSION');
if(!$GLOBALS['LT_BROWSER_VERSION']) $GLOBALS['LT_BROWSER_VERSION'] ="63.0";

$GLOBALS['LT_OPERATING_SYSTEM'] = getenv('LT_OPERATING_SYSTEM');
if(!$GLOBALS['LT_OPERATING_SYSTEM']) $GLOBALS['LT_OPERATING_SYSTEM'] = "win10";

class LambdaTest{
	
   protected static $driver;

   public function testAdd() {		
		
		$url = "https://". $GLOBALS['LT_USERNAME'] .":" . $GLOBALS['LT_ACCESS_KEY'] ."@hub.lambdatest.com/wd/hub";		
		$desired_capabilities = new DesiredCapabilities();
		$desired_capabilities->setCapability('browserName',$GLOBALS['LT_BROWSER']);
		$desired_capabilities->setCapability('version', $GLOBALS['LT_BROWSER_VERSION']);
		$desired_capabilities->setCapability('platform', $GLOBALS['LT_OPERATING_SYSTEM']);
		$desired_capabilities->setCapability('name', "PHPTestSample");
		$desired_capabilities->setCapability('build', "LambdaTestSampleApp");
		$desired_capabilities->setCapability('network', true);
		$desired_capabilities->setCapability('visual', true);
		$desired_capabilities->setCapability('video ', true);
		$desired_capabilities->setCapability('console', true);
		
		self::$driver = RemoteWebDriver::create($url, $desired_capabilities); 		
				
		$itemName = 'Yey, Lets add it to list';
        self::$driver->get("https://4dvanceboy.github.io/lambdatest/lambdasampleapp.html");
        $element1 = self::$driver->findElement(WebDriverBy::name("li1"));
		$element1->click();
			
            
		$element2 = self::$driver->findElement(WebDriverBy::name("li2"));
        $element2->click();
			
		$element3 = self::$driver->findElement(WebDriverBy::id("sampletodotext"));
		$element3->sendKeys($itemName);
			
		$element4 = self::$driver->findElement(WebDriverBy::id("addbutton"));			
		$element4->click();
			
        self::$driver->wait(10, 500)->until(function($driver) {
           $elements = $driver->findElements(WebDriverBy::cssSelector("[class='list-unstyled'] li:nth-child(6) span"));
           return count($elements) > 0;
        });
		
		self::$driver->quit();
    }
			
}

  $lambdaTest = new LambdaTest();
  $lambdaTest->testAdd();
  
?>

Configuration Of Your Test Capabilities

Step 4: In the test script, you need to update your test capabilities. Here, the code will select the basic capabilities such as OS, browser, browser version and so on.

//Basic Test Configurations For PHP

$capabilities = array(
    "build" => "your build name",
    "name" => "your test name",
    "platform" => "macOS High Sierra",
    "browserName" => "Firefox",
    "version" => "64.0",
    "resolution" => "1280x1024",
    "selenium_version" => "3.13.0",
    "screenshot" => true,
    "firefox.driver" => v0.23.0
    )

Note: You can generate capabilities for your test requirements with the help of our inbuilt Capabilities Generator tool.

Executing the Test

Step 5: The tests can be executed in the terminal using the following command:

php tests/LambdaTest.php

Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard. LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.

Testing Locally Hosted or Privately Hosted Projects

---

You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid cloud using LambdaTest Tunnel app. All you would have to do is set up an SSH tunnel using LambdaTest Tunnel app and pass toggle tunnel = True via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are made live.

Refer our LambdaTest Tunnel documentation for more information.

Here’s how you can establish LambdaTest Tunnel.

Download the binary file of:

• LambdaTest Tunnel for Windows

• LambdaTest Tunnel for Mac
• LambdaTest Tunnel for Linux

Open command prompt and navigate to the binary folder.

Run the following command:

LT -user {user’s login email} -key {user’s access key}

So if your user name is lambdatest@example.com and key is 123456, the command would be:

LT -user lambdatest@example.com -key 123456

Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on to set the tunnel value to true by adding the following line in your config files:

Tunnel Capability

 "tunnel" => true
