minitest-rails

Minitest integration for Rails 7.0

Install

gem install minitest-rails

This installs the following gems:

• minitest

Configure

Create a new rails app:

rails new MyApp

Choosing a version

This gem follows the versioning of Rails. If you are running Rails 7.0, specify the corresponding 7.0 release in the Gemfile. For example:

gem "minitest-rails", "~> 7.0.0"

If you are running Rails 6.x, specify the corresponding 6.x release in the Gemfile. For example, if you are using Rails 6.1 you will specify:

gem "minitest-rails", "~> 6.1.0"

If you are running Rails 5.x, specify the corresponding 5.x release in the Gemfile. For example, if you are using Rails 5.2 you will specify:

gem "minitest-rails", "~> 5.2.0"

Or, if you prefer to run the previous release for Rails 5.x, specify the 3.x release in the Gemfile:

gem "minitest-rails", "~> 3.0"

If you are running Rails 4.1 or 4.2, specify the 2.x release in the Gemfile:

gem "minitest-rails", "~> 2.0"

If you are running Rails 4.0 or earlier, you really need to upgrade. But if you are you need to specify the 1.x release in the Gemfile:

gem "minitest-rails", "~> 1.0"

Installing

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 using the Minitest::Spec DSL with the standard model, controller, resource, and other generators:

rails generate model User

And you can specify generating the tests without the Minitest::Spec DSL on any of the generators by providing the --no-spec option:

rails generate model User --no-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: false, fixture: false
end

Running Tests

To run your tests use the rails test that ship with rails.
