Installation

Manual

Emacs

Just drop minitest.el. somewhere in your load-path. And:

(add-to-list 'load-path "~/emacs.d/vendor")
(require 'minitest)

Spacemacs

The Spacemacs Ruby layer supports minitest-emacs as one of its configurable test runners. To set the default Ruby test runner to use this package, edit the ruby layer entry in the dotspacemacs-configuration-layers list defined in your .spacemacs file:

dotspacemacs-configuration-layers
'(
  (ruby :variables
        ruby-test-runner 'minitest)
)

See the Spacemacs Ruby layer documentation for more info.

Using Marmalade or MELPA

M-x package-install minitest

Configuration

To enable minitest mode on ruby files, simply add to your dotfile:

(add-hook 'ruby-mode-hook 'minitest-mode)

In case you are using Spacemacs, add the above line to dotspacemacs/user-config which is towards the end of your .spacemacs dotfile:

(defun dotspacemacs/user-config ()
	(add-hook 'ruby-mode-hook 'minitest-mode))

If you have another hook already in here make sure to add this hook within its own set of parenthesis so that there is only one hook per parenthesis.

Rails

If you are working on a Rails project, you can set minitest-use-rails to true in order to use the bin/rails test command when running examples.

Docker

You can run tests inside a Docker container by setting minitest-use-docker to true and minitest-docker-container to the name of the container. By default this will use the command docker-compose exec to run the minitest command, which assumes you already have the specified container running. To customize the command, edit the minitest-docker-command variable.

Snippets

If you have yasnippet installed, you can load the snippets:

(eval-after-load 'minitest
  '(minitest-install-snippets))

Scroll Position

The compilation-scroll-output variable, when set to t, scrolls to the bottom of the test output. When set to nil, the test output buffer stays scrolled to the top.

Before version 0.10.0, this variable was set to t before running tests, but after version 0.10.0 it is not set explicitly anymore. In order to get back the old behavior, just set compilation-scroll-output to t yourself.
