Ruby version is 2.5.0
Tests are ran on mock, fedora-rawhide-x86_64.
Feedback appreciated.

no acceptor (port is in use or requires root privileges) (RuntimeError)

I think you are running another guard process.

[jackorp]

I don't think that is the problem. The tests are run in mock container environment, so no additional guard processes should be running.

Any luck with this?
