Laravel Dusk error: Failed to connect to localhost port 9515: Connection refused

Question

As the title says, I\'ve go a clean install of Laravel 5.4 and the latest Homestead (1.0.1). However, when I run a simple Dusk test case I get the following error:

Answer 1

On Ubuntu Linux 16.04, I got this to work:

Install Chromium & dependencies for headless testing

sudo apt-get -y install chromium-browser xvfb gtk2-engines-pixbuf xfonts-cyrillic xfonts-100dpi xfonts-75dpi xfonts-base xfonts-scalable imagemagick x11-apps

Create a customDuskCommand

Which extends the original, with this handle method:

public function handle()
{
    $xvfb = (new ProcessBuilder())
        ->setTimeout(null)
        ->setPrefix('/usr/bin/Xvfb')
        ->setArguments(['-ac',  ':0', '-screen', '0', '1280x1024x16'])
        ->getProcess();

    $xvfb->start();

    try {
        parent::handle();
    } finally {
        $xvfb->stop();
    }

    return;
}

This will start Xvfb for headless testing before executing the tests and stop the process after testing completes.

Edit: And make sure vendor/laravel/dusk/bin/chromedriver-linux is executable.
