Laravel Dusk in Docker: Selenium can't start Chrome

[osmianski]

• Laravel v10.9.0
• PHP v8.2.3
• laravel/dusk v7.7.1
• orchestra/testbench v8.5.1
• orchestra/testbench-dusk v8.6.0
• orchestra/dusk-updater v2.0.1
• pestphp/pest v2.6.0

Description

I'm developing a package with an accompanying example application (in the /example-app directory) in a non-Sail Docker environment.

Now, I want to add browser tests that work with the example application - and I can't make Laravel Dusk to work. It seems that the test connects to Selenium successfully, but Selenium for some reason can't start Chrome, or can't establish connection with it.

Any ideas are welcome.

Pest test

The test, tests/Browser/ExampleTest.php:

it('starts a browser', function () {
    $this->browse(function ($browser) {
        $browser->visit('/')->assertSee('Laravel');
    });
});

The base class for browser tests, tests/BrowserTestCase.php:

use Facebook\WebDriver\Remote\RemoteWebDriver;
use Orchestra\Testbench\Dusk\Options as DuskOptions;
use Orchestra\Testbench\Dusk\TestCase as BaseTestCase;

class BrowserTestCase extends BaseTestCase
{
    public static function prepare(): void
    {
        // This method is empty on purpose. In the parent class, it starts
        // the local headless Chrome to be used with the local Selenium.
        //
        // However, our Selenium runs in a separate container, and the
        // headless Chrome runs there, too.
        //
        // So, we don't need to start the local headless Chrome.
    }

    protected function driver(): RemoteWebDriver
    {
        DuskOptions::withoutUI();

        // this is my experiments with Chrome start parameters, none of them made things better
        DuskOptions::ignoreSslErrors();
        DuskOptions::addArgument('--ignore-certificate-errors-spki-list');
        DuskOptions::addArgument('--verbose');
        DuskOptions::addArgument('--whitelisted-ips');
        DuskOptions::addArgument('--disable-dev-shm-usage');

        return parent::driver();
