Run rails test inside docker container using vimtest
let g:test#ruby#rails#executable = 'docker compose run -ti --rm backend-test rails test'
# Replace backend-test with the name of the service.
You wouldn't want to run it in the main service because it ends up using the resetting development database.

Manjaro I3 Installation Notes

Install notes for Manjaro

  1. Install broadcom-wl-dkms to get 5G. Default installed kernel linux56 didn't have kernel headers to install the dkms module. So had to upgrade to new kernel.
sudo mhwd -i linux58
sudo pacman -S linux58-headers
sudo pacman -S broadcom-wl-dkms
