minitest-rails¶ ↑

MiniTest integration for Rails 3.x

<img src=“https://secure.travis-ci.org/blowmage/minitest-rails.png” alt=“Build Status” />

Install¶ ↑

gem install minitest-rails

This installs the following gems:

minitest

Configure¶ ↑

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.

Usage¶ ↑

We aim to expose MiniTest with minimal changes for testing within Rails. Because of this, we allow Test::Unit and MiniTest tests to live side by side. Your test classes will inherit from MiniTest::Rails::ActiveSupport::TestCase a opposed to ActiveSupport::TestCase. You can use the MiniTest::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

Overriding Test::Unit¶ ↑

Of course, you may not want to maintain separate Test::Unit and MiniTest tests. If this is the behavior you are wanting, simply add the following to your test_helper.rb file:

require "minitest/rails"
MiniTest::Rails.override_testunit!

Capybara¶ ↑

You can use Capybara in your acceptance/integration tests by adding minitest-rails-capybara as a dependency.

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

And add the following to your test helper file:

require "minitest/rails/capybara"

See the minitest-rails-capybara project for more information.

Incompatibilities¶ ↑

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