minitest-rails¶ ↑
Minitest
integration for Rails
4.1+
Install¶ ↑
gem install minitest-rails
This installs the following gems:
minitest
Configure¶ ↑
Create a new rails app:
rails new MyApp
Add minitest-rails
to the Gemfile:
gem "minitest-rails"
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.
Usage¶ ↑
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
Running Tests¶ ↑
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:
Rake::Task["test:run"].enhance ["test:presenters"]
Using 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
Capybara¶ ↑
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.
