2. add guard

   cat >> Gemfile
   gem "guard"
   gem "guard-rspec"
   

   bundle
3. guard init rspec configure guard
4. vi open neovim
5. :e spec/tennis_spec.rb edit the spec file
6. :vsplit lib/tennis.rb edit the implementation file
7. :vsplit | terminal vsplit a terminal, or vs | te
8. guard in terminal
9. <CTRL>-\ <CTRL>-n to go to navigation mode in terminal under neovim
10. <CTRL>-w l to jump to a different split (l for one to right)
11. :w save the test and the terminal should re-run tests
12. <CTRL>-w h to jump back to the left
