This package provides an interface for dealing with the [Mutant](https://github.com/mbj/mutant) testing tool, enabling one to easily launch it from a `.rb` file or even from a `dired` buffer. The generated output is nicely formatted and provides direct links to the errors reported by the mutations. I've tried to mimic the `rspec-mode` overall experience as much as possible. ; Installation: This package can be installed via `MELPA`, or manually by downloading `mutant.el` and adding it to your init file, as it follows: ```elisp (add-to-list 'load-path "/path/to/mutant") (require 'mutant) ``` For having `mutant-mode` enabled automatically, I suggest you to do the following: ```elisp (add-hook 'ruby-mode-hook 'mutant-mode) ```
