gem install minitest-rails

This installs the following gems:

minitest

Create a new rails app without Test::Unit:

rails new MyApp --skip-test-unit

Add minitest-rails to the :test and :development groups in Gemfile:

group :test, :development do
  gem 'minitest-rails'
end

Next run the installation generator with the following:

rails generate mini_test:install

This will add the minitest_helper.rb file to the test directory.

This project aims to enable MiniTest within the Rails TestCase classes. Your test will continue to inherit from ActiveSupport::TestCase, which will now support the spec DSL. You can generate test files with the standard model, controller, resource, and other generators:

rails generate model User

And you can specify generating the tests using the MiniTest::Spec DSL on any of the generators by providing the --spec option:

rails generate model User --spec

And you can specify not generating the fixture for a model by providing the --skip-fixture option:

rails generate model User --skip-fixture

You can also set these as defaults by adding the following to the config/application.rb file:

config.generators do |g|
  g.test_framework :mini_test, :spec => true, :fixture => false
end

You can use Capybara for feature tests by adding minitest-rails-capybara as a dependency. See the README for more information: github.com/blowmage/minitest-rails-capybara

Efforts have been made to be compatible with Ruby 1.8.7, but some rough edges may remain. You have been warned.

Existing tests that call describe will not work, since describe is used by MiniTest::Spec blocks.
