Changing $DISPLAY to :5 doesn't help either. I'm in a headless WSL environment which was not a problem earlier ...

We now use javascript in our project and therefore had to include a headless Browser in our tests which apparently does not work well with WSL

@LinqLover I don't want to spam Discord so I reply here:
Vagrant is a manager for virtual machines that uses VirtualBox in the Background. The tests with a headless firefox work without problems in a VM created by our Vagrantfile. I'm not sure if Vagrant works good with Windows but it's worth a try because the setup is really easy. Nevertheless I would recommend using Windows for developing ;)

[LinqLover]

Thanks for the pointer. I will try that out when I need it the next time ... Unfortunately, installing dev stuff directly in Windows is not that easy as installing it in Linux/WSL, and Vagrant sounds a quite heavy (i.e. resources-extensive) tool ... :-)

[felixauringer]

I do not think that headless VirtualBox VM are really resource-extensive:

2% of my RAM are aproximately 640MB and there is only real CPU load when the server responds to a request / runs a test. That's definitely less than RubyMine 😅
But I think you mentioned the reason why Linux is better for developing than Windows ;)

[LinqLover]

Well, 640 MB is a lot of RAM - a VS Code window only consumes half as much space. But that's probably out of topic. :-)

So will we leave this ticket open until the installation instructions in the README.md are again correctly (which do not mention the setup of any x-server solution ATM)?

The setup just assumes that Linux is used because it is most common but feel free to add any Windows specific requirements after you figured them out :)
