Subject: How to get the minitest capture_io method found in my specs?

This is my `spec/helper.rb` file:

    require 'minitest/autorun'
    require 'minitest/spec'
    require_relative '../lib/launcher'

    class MiniTest::Spec
      include MiniTest::Assertions
    end

And this is the spec file:

    require 'helper'

    describe Launcher do
      it "should get the stdout" do
        out, err = capture_io do
          warn "You did a bad thing"
        end
        err.should =~ /bad/
      end
    end

But when I run the spec:

    ± rake spec
    /Users/millisami/.rvm/rubies/ruby-1.9.3-p194/bin/ruby -S rspec
./spec/launcher_spec.rb -Ispec:lib
    F

    Failures:

      1) Launcher should be a launcher for cloud
         Failure/Error: out, err = capture_io do
         NoMethodError:
           undefined method `capture_io' for
#<RSpec::Core::ExampleGroup::Nested_1:0x000001012a4840>
         # ./spec/launcher_spec.rb:5:in `block (2 levels) in <top
(required)>'

    Finished in 0.00044 seconds
    1 example, 1 failure

    Failed examples:

    rspec ./spec/launcher_spec.rb:4 # launcher should be a launcher for
cloud
    rake aborted!
    /Users/millisami/.rvm/rubies/ruby-1.9.3-p194/bin/ruby -S rspec
./spec/launcher_spec.rb -Ispec:lib failed

    Tasks: TOP => spec

But when I do this with the default MiniTest::Unit way, it works?
And why not the spec way?
