Error when trying to run a minitest unit test

I get the following error when trying to run a minitest unit test with ruby test/test_foo.rb:

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'
From:
  /home/emile/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/minitest/autorun.rb:15:```

test_foo.rb looks like this:

require 'minitest/autorun'

class TestFoo < MiniTest::Test
 #stuf
end

My Gemfile does contain gem 'minitest' and test_foo.rb does contain require 'minitest/autorun', yet I still get the warning.

Is this a bug? Any ideas?

Run your test using bundle exec ruby test/test_foo.rb to make sure you use your bundled gems (in this case minitest).

Just running ruby test/test_foo.rb will use your globally installed Rubygems.

If you want to dig around a little more, try looking in /home/emile/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/minitest/autorun.rb, around line 15.

I've interepreted the warning literally and added the line gem 'minitest' before the line require 'minitest/autorun', and that seems to work. Odd, or is this expected?

This is expected. It tells ruby to use the gem version and not the standard library version.
