Laravel Dusk screenshot

In my DuskTestCase file I have the below in my driver() function.

protected function driver()
{
    $options = (new ChromeOptions())->addArguments([
        '--disable-gpu',
        '--headless',
    ]);

    $driver = RemoteWebDriver::create(
        'http://selenium:4444/wd/hub',
        DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY,
            $options
        )
    );

    $size = new WebDriverDimension(1280, 2000);
    $driver->manage()->window()->setSize($size);

    return $driver;
}

You should just be able to configure it with the right dimensions you need.

You only need to add '--window-size=1920,1080' in $options. This will apply a 1920x1080 screen resolution to all your Dusk tests. Feel free to adjust to whatever window size you want.

So your DuskTestCase.php file should look like this:

protected function driver()
{
    $options = (new ChromeOptions())->addArguments([
        '--disable-gpu',
        '--headless',
        '--window-size=1920,1080',
    ]);

    $driver = RemoteWebDriver::create(
        'http://selenium:4444/wd/hub',
        DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY,
            $options
        )
    );

}

Regarding the path issue, you can set it with Browser::$storeScreenshotsAt in setUp method of your test case class.

protected function setUp()
{
    parent::setUp();
    Browser::$storeScreenshotsAt = '/path/to/your/screenshots';
}

Default location of Browser::$storeScreenshotsAt is set in setUp method of the grand parent test case class. So, make sure that you set Browser::$storeScreenshotsAt after calling parent::setUp(), otherwise it will be overwritten by the default.
