Running tests with vim and tmux

After using vim and neovim for almost a year now I've come to the point when frustration I had with running test with vim made me think about ideal workflow for running tests (at least in command line, but some rules apply to GUI).

Below you can read my thoughts about ideal workflow, a summary of problems with current workflows (at least that I know of, but I think I've tried them all) and my own new (well, at least I think it's new) solution to them.
