Can I perform form submissions and handle file uploads using Symfony Panther?

Yes, you can perform form submissions and handle file uploads using Symfony Panther. Symfony Panther is a browser testing and web scraping library for PHP that leverages the WebDriver protocol. It allows you to control real browsers such as Google Chrome to interact with web applications, including filling out and submitting forms as well as uploading files.

Here's how you can perform form submissions and handle file uploads with Symfony Panther:

Form Submission

To submit a form using Symfony Panther, you first need to select the form, fill in the fields, and then use the submit method on the form. Below is an example of how you might submit a simple login form:

use Symfony\Component\Panther\PantherTestCase;

class MyPantherTest extends PantherTestCase
{
    public function testFormSubmission()
    {
        $client = static::createPantherClient(); // Create client
        $crawler = $client->request('GET', 'http://example.com/login'); // Navigate to the login page

        // Select the form and fill in the details
        $form = $crawler->selectButton('Login')->form([
            'username' => 'my_username',
            'password' => 'my_password',
        ]);

        // Submit the form
        $client->submit($form);

        // Perform assertions or further interactions
    }
}

File Uploads

Handling file uploads with Symfony Panther involves locating the file input element in the form and setting its value to the file path of the file you want to upload. Here's an example:

use Symfony\Component\Panther\PantherTestCase;

class MyPantherTest extends PantherTestCase
{
    public function testFileUpload()
    {
        $client = static::createPantherClient(); // Create client
        $crawler = $client->request('GET', 'http://example.com/upload'); // Navigate to the upload page

        // Find the form and file input element
        $form = $crawler->selectButton('Upload')->form();
        $fileInput = $crawler->filter('input[type="file"]');

        // Set the file path to the file input for upload
        $fileInput->setValue('/path/to/your/file.txt');

        // Submit the form with the file
        $client->submit($form);

        // Perform assertions or further interactions
    }
}

Remember to replace http://example.com, username, password, Login, Upload, and /path/to/your/file.txt with the actual values relevant to your application.

Symfony Panther will handle the file upload as a browser would, so you should ensure that your test environment has access to the file you're trying to upload, and the file path is correct.

Note: When working with Symfony Panther, it's important to have a WebDriver server (like ChromeDriver or GeckoDriver) running, and the browser it controls must be installed on the same machine where your tests are running.

Keep in mind that Symfony Panther is designed for testing and web scraping, and it should be used in a manner that respects the terms of service of the websites you're interacting with.
