I spend most of time in Emacs and Terminal. I make code changes in emacs and switch to terminal to run the tests. Wouldn't it be nice if I didn't have to switch and can do it inside emacs without switching ? I tried `shell-mode` and `inferior shell` (python) for this, but it didn't somehow work, till I found `vterm`

How to use Emacs as an IDE with Integrated Terminal (Instructions for Doom emacs, but should work for other configurations as well)
