Remind user to run test suite before pushing code. Untested idea.

checkpush.sh

function checkpush(){
  echo "Did you run the test suite?"
  select yn in "Yes" "No"; do
      case $yn in
          Yes ) git push; break;;
          No ) echo "Better run the tests first." exit;;
      esac
  done
}

export -f checkpush

alias 'git push' = `checkpush`
