I am new to Ruby on Rails and testing. When I run rake test I get the following error:

/Users/jarvis/.rvm/gems/ruby-1.9.2-p180@rails3tutorial/gems/rack-1.3.4/lib/rack/backports
/uri/common_192.rb:53: warning: already initialized constant WFKV_
/Users/jarvis/.rvm/gems/ruby-1.9.2-p180@rails3tutorial/gems/turn-0.8.3/lib/turn/autorun
/minitest.rb:14:in `<top (required)>': MiniTest v1.6.0 is out of date. (RuntimeError)
`gem install minitest` and add `gem 'minitest' to you test helper.

/active_support/dependencies.rb:240:in `require'

I did gem install minitest and now it says to add gem 'minitest' to my test helper. Is this test/test_helper.rb, and if so, how do I "add" minitest?

Edit your Gemfile so that the gem is specified under the test group, like so:

group :test do
  gem "minitest"
end
