Adjust the size of the window/screenshot

[OskarStark]

I tried sth like:

<?php

declare(strict_types=1);

namespace App\Tests\Acceptance\Util;

use Facebook\WebDriver\WebDriverDimension;
use Symfony\Component\Panther\Client as PantherClient;
use Symfony\Component\Panther\PantherTestCase;

class ScreenshotTestCase extends PantherTestCase
{
    protected static function createPantherClient(array $options = [], array $kernelOptions = [], array $managerOptions = []): PantherClient
    {
        $client = self::createPantherClient();

        $size = new WebDriverDimension(1400, 4000);
        $client->manage()->window()->maximize()->setSize($size);

        return $client;
    }
}

But the size of the screenshot doesn't change 🤔

Hey there,

had the same problem. Just add --window-size=1400,900 as chrome arguments :)

Hey, I'm facing the same issue! Could you give us a code example of where chrome arguments go, @marco-kretz ? Thanks!

[marco-kretz]

I'm just using env-vars for this. That's what I have in my .env:

PANTHER_CHROME_ARGUMENTS="--disable-dev-shm-usage --window-size=1400,900 --no-sandbox --headless --hide-scrollbars"

[shadowc]

Ahh, I see! Thank you! I'll try this!

That TOTALLY works! May be in the future we can configure these arguments somewhere within the panther client creation (or a panther.xml.dist file or similar in our projects!)

You can totally do that already :)

I see! May be this is not apparent from createPantherClient.

If I do:

$this->client = static::createPantherClient(
    ['external_base_uri' => 'https://localhost:8000'],
    ['HTTPS' => true],
    ['capabilities' => [
        'acceptInsecureCerts' => true,
    ]],
);

Because I want to use an external server with https, then I need to figure out how this translates to the createChromeClient signature.

[shadowc]

From panther's source code:

if (static::CHROME === $browser) {
            self::$pantherClients[0] = self::$pantherClient = Client::createChromeClient(null, null, $managerOptions, self::$baseUri);
        } else {
            self::$pantherClients[0] = self::$pantherClient = Client::createFirefoxClient(null, null, $managerOptions, self::$baseUri);
        }

May be we need to accept browser arguments from within createPantherClient to make it more accessible?

It would appear by looking at the source code (if I'm not wrong) that if I call Client::createChromeClient I won't have started a WebServer (which I guess it's fine in my case, but not ALL cases) and I won't boot a kernel. What implications does this have for the test case?
