Test

RubyMine provides integration with the most popular frameworks used for testing Ruby/Rails applications. You can run multiple or individual tests, navigate between a test and test subject, create missing tests, and so on.

Supported testing frameworks and tools

The following testing frameworks and tools are supported:

• Minitest

  Minitest is a testing framework that supports TDD and BDD approaches, mocking, and benchmarking. Before running Minitest tests in RubyMine, make sure that the 'minitest' gem is added to the Gemfile and installed to the project's interpreter. RubyMine requires the Minitest gem v5.0 or later. You can use the older versions and launch tests from the console, but RubyMine’s GUI actions will be unavailable.

  The minitest-reporters gem is no longer in use. If you use Minitest, make sure to update your Minitest configuration file (/test/test_helper.rb): replace MiniTest::Reporters.use! with Minitest::Reporters.use! unless ENV['RM_INFO'].

• RSpec

  RSpec is a popular BDD framework for testing Ruby/Rails applications. Depending on your project type (Ruby or Rails), use the rspec or rspec-rails gem.

• Cucumber

  Cucumber is a BDD testing tool that uses the Gherkin language for writing test scenarios. For more information about Cucumber features supported in RubyMine, refer to Cucumber.

• Test::Unit

  Test::Unit is a legacy TDD framework for testing Ruby/Rails code.

Apart from the frameworks listed above, RubyMine supports the following testing libraries:

• Shoulda

  Apart from standard Minitest and RSpec tests, RubyMine allows you to run tests that use Shoulda.

• FactoryBot

  FactoryBot is a library for setting up Ruby objects as test data that replaces fixtures. RubyMine allows you to safely rename or delete factories, complete factory attributes, and methods (for example, create and build), navigate from models to factories and vice-versa, and so on.

• SimpleCov

  SimpleCov is an analysis tool used by RubyMine to measure code coverage. Learn how to do this from the Code coverage topic.

• Capybara

  Capybara is a web-based test automation tool that simulates scenarios for user stories and automates web application testing for behavior-driven software development.
