If you, like me, have shortcuts and muscle memory built in neovim (or vim) to run tests while you develop, you might get frustrated when you change from a local development environment to a local dockerized development environment.
I use the plugin vim-test with Neoterm and four shortcuts in neovim to run the tests which DO NOT work when you are working on a dockerized rails application.
After banging my head on the keyboard because I had to run rspec manually, it came to my mind: “I can bloody setup an alias in the shell and I can just go back to my super productive flow! - idiot”. I ran the following in neoterm:
alias rspec='docker exec -it <container> rspec'
and changed the executable in then neovim configuration for vim-test (by default it
bundle exec rspec)
let test#ruby#rspec#executable = 'rspec'
and that’s it, the speed was back!
