DESCRIPTION:¶ ↑

autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests.

minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead.

FEATURES/PROBLEMS:¶ ↑

Continually and intelligently test only those files you change with autotest.

SYNOPSIS:¶ ↑

% autotest
# ... tests run ...

AUTOTEST TIPS¶ ↑

Setting up your project with a custom setup is easily done by creating a “.autotest” file in your project. Here is an example of adding some plugins, using minitest as your test library, and running rcov on full passes:

require 'autotest/restart'

Autotest.add_hook :initialize do |at|
  at.testlib = "minitest/autorun"
end

Autotest.add_hook :all_good do |at|
  system "rake rcov_info"
end if ENV['RCOV']

Do note, since minitest ships with ruby 1.9, if you want to use the latest minitest gem you need to ensure that the gem activation occurs! To do this, add the gem activation and the proper require to a separate file (like “.minitest.rb” or even a test helper if you have one) and use that for your testlib instead:

.minitest.rb:

gem "minitest"
require "minitest/autorun"

.autotest:

Autotest.add_hook :initialize do |at|
  at.testlib = ".minitest"
end

If you prefer to suffix test files with “_test.rb” (instead of the default which prefixes test files with “test_”) you can change the mapping by installing the autotest-suffix plugin. To do this first install the autotest-suffix gem:

$ gem install autotest-suffix

Then add the following to the “.autotest” file:

require "autotest/suffix"

If you prefer minitest/spec to minitest/unit, you can still use autotest by installing the autotest-spec plugin. To do this first install the autotest-spec gem:

$ gem install autotest-spec

Then add the following to the “.autotest” file:

require "autotest/spec"

If you use autotest/bundler, include minitest-autotest in your Gemfile:

gem "minitest-autotest"

Otherwise, you may get this error message when running autotest:

invalid option: --server
