Turbux is designed to speed up your TDD cycle by using a single key mapping to run the most relevant test based on the current file in vim. It uses tmux's scriptability to send commands to a chosen pane in your tmux session.
For more information, see the documentation.
This plugin depends on vim-dispatch, tslime.vim, vim-tmux-runner, or vimux, whichever is available, and becomes really awesome when used with rails.vim. It also makes the assumption that you're using tmux.
Note: Due to a bug in the original tslime.vim plugin, please use my fork.
