/Users/xavier/.gem/ruby/2.1.0/gems/fivemat-1.2.1/lib/fivemat/minitest.rb:3:in `<top (required)>': undefined method `runner=' for Minitest::Unit:Class (NoMethodError)
        from /Users/xavier/.gem/ruby/2.1.0/gems/fivemat-1.2.1/lib/fivemat/minitest/autorun.rb:2:in `require'
        from /Users/xavier/.gem/ruby/2.1.0/gems/fivemat-1.2.1/lib/fivemat/minitest/autorun.rb:2:in `<top (required)>'
        from test.rb:1:in `require'
        from test.rb:1:in `<main>'

Using the following files:

source 'https://rubygems.org'
gem 'fivemat'
gem 'minitest', '~> 5'

require 'fivemat/minitest/autorun'

class TestWorking < MiniTest::Unit::TestCase
  def test_works
    assert_equal 1, 1
  end
end

Changing ~> 5 to ~> 4 (or using the version bundled in stdlib) works fine.

I'm not going to be fixing this because I don't use minitest. I noticed it while testing some RSpec changes hadn't broken anything.

Thanks for the heads up. I hope Cucumber has some breaking changes in the works too.
