Is there a way to simulate different user agents with Symfony Panther?

Yes, Symfony Panther allows you to simulate different user agents when making requests to a website. Symfony Panther is a browser testing and web scraping library for PHP that leverages the WebDriver protocol. It uses ChromeDriver or GeckoDriver to control actual browsers like Google Chrome or Firefox.

To simulate a different user agent using Symfony Panther, you need to create a new instance of Panther's WebDriver with the desired user agent string. You can do this by passing the user agent string as an argument to the WebDriver's capabilities.

Here is an example in PHP of how to set a custom user agent in Symfony Panther:

<?php

require __DIR__.'/vendor/autoload.php'; // Make sure to include the autoload file

use Symfony\Component\Panther\PantherTestCase;

class MyTest extends PantherTestCase
{
    public function testUserAgent()
    {
        // Define your custom user agent string
        $customUserAgent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36';

        // Create a new client instance with the custom user agent
        $client = static::createPantherClient([
            'capabilities' => [
                \Facebook\WebDriver\WebDriverCapabilityType::BROWSER_NAME => 'chrome',
                \Facebook\WebDriver\WebDriverCapabilityType::CHROME => [
                    'args' => ["--user-agent={$customUserAgent}"],
                ],
            ],
        ]);

        // Now, the client will use the specified user agent for all requests
        $crawler = $client->request('GET', 'https://example.com');

        // Perform any actions or assertions you need
    }
}

// Run the test
$test = new MyTest();
$test->testUserAgent();

In this example, we are extending the PantherTestCase which provides a convenient API for creating clients and crawlers. We then define a custom user agent string and use it when creating a Panther client. The --user-agent argument is passed to the ChromeDriver, which then simulates that user agent when making requests.

Please note that the capabilities structure may vary depending on the driver you're using (e.g., ChromeDriver or GeckoDriver) and the browser (e.g., Chrome or Firefox).

Remember to include the necessary namespaces and dependencies in your composer.json file and install them using Composer. Symfony Panther requires PHP 7.1 or higher and some additional PHP extensions, so make sure your environment meets these requirements.
