MiniTest

Prerequisites

• minitest is downloaded and installed on your computer. 5.0+

  RubyMine supports minitest versions higher than 3.1.0

• minitest-reporters, version 0.5.0 or higher, is downloaded and installed on your computer. This gem is required for integration with RubyMine test runner.
• For Windows, win32Console, version '1.3.0' is downloaded and installed.
• The gems have to be properly attached to your project. For example, if you use the Bundler for managing gems, the required gems should be added to the Gemfile of your project.

  For example, the Gemfile can contain the following code:

  group :test do
      if RUBY_PLATFORM =~ /(win32|w32)/
          gem "win32console", '1.3.0'
      end
      gem "minitest"
      gem "minitest-reporters", '>= 0.5.0'
  end
                      

• Depending on the version of minitest-reporters gem, one of the following code fragments is added to your tests (if you are working with a Rails application, it is better accomplished with test/test-helper.rb file ):
  • Version 0.8.0 and higher

    require 'minitest/reporters'
    MiniTest::Reporters.use!
    

  • Older versions

    require 'minitest/reporters'
    MiniTest::Unit.runner = MiniTest::SuiteRunner.new
    if ENV["RM_INFO"] || ENV["TEAMCITY_VERSION"]
      MiniTest::Unit.runner.reporters << MiniTest::Reporters::RubyMineReporter.new
    elsif ENV['TM_PID']
      MiniTest::Unit.runner.reporters << MiniTest::Reporters::RubyMateReporter.new
    else
      MiniTest::Unit.runner.reporters << MiniTest::Reporters::ProgressReporter.new
    end
                    

    The above code enables specific results reporter, which depends on the environment where tests have been launched: RubyMine, TeamCity CI server, or TextMate text editor/ terminal. This approach is helpful, when you work in a mixed team that uses different IDEs, or text editors.

    Note

    It is important to execute this code at the test initialization, before running the tests.

• The names of the minitest files match the patterns *_test.rb, or test_*.rb. This limitation is not related to MiniTest, but rather is imposed by RubyMine's code insight.
