Minitest integration for
gem install minitest-rails
This installs the following gems:
Create a new rails app without Test::Unit:
rails new MyApp --skip-test-unit
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
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
rails generate model User --spec
And you can specify not generating the fixture for a model by providing the
rails generate model User --skip-fixture
You can also set these as defaults by adding the following to the
config.generators do |g| g.test_framework :minitest, spec: true, fixture: false end
Running Tests¶ ↑
To run your tests use the
rake test that ship with rails. For a complete list run
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:
Rails 4.0 or earlier¶ ↑
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 Compatibility¶ ↑
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.
