Minitest integration for Rails 4.1+
gem install minitest-rails
This installs the following gems:
Create a new rails app without Test::Unit:
rails new MyApp --skip-test-unit
Add minitest-rails to the Gemfile:
If you are running Rails 4.0 or earlier, be sure to specify a 1.x release in the Gemfile:
gem "minitest-rails", "~> 1.0"
Next run the installation generator with the following:
rails generate minitest:install
This will add the test_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 :minitest, spec: true, fixture: false end
To run your tests use the rake test that ship with rails. For a complete list run rake -T.
To add additional testing tasks, define them in your Rakefile or a file in lib/tasks like so:
Rails::TestTask.new("test:presenters" => "test:prepare") do |t| t.pattern = "test/presenters/**/*_test.rb" end
If you want your new task to be run when you run rake test, also add the following:
For information on using minitest-rails with Rails 3.0 through 4.0, see the README for the 1.x branch: github.com/blowmage/minitest-rails/tree/1.x#readme
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
RSpec and Minitest's spec DSL are incompatible and both cannot be loaded at the same time. If your tests using the spec DSL are not running it is likely the RSpec DSL is also loaded. Check the dependencies and make sure RSpec is only loaded when running the specs.
If you need to use some RSpec features with minitest-rails require only the needed gems. e.g. To use RSpec mocks with minitest-rails require the “rspec-mocks” gem only, and not the main “rspec” gem which activates the RSpec DSL.
