Forum: Ruby 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?

This isn't necessary. In fact, you only need the autorun and launcher 
lines.

I'd start by cleaning up the above. it works for me:

10011 % ruby -Ilib -rminitest/autorun -e 'describe true do it "works" do 
x = capture_io do puts "hi" end; p x end end'
Run options: --seed 27063

# Running tests:

["hi\n", ""]
.

Finished tests in 0.000760s, 1315.7895 tests/s, 0.0000 assertions/s.

1 tests, 0 assertions, 0 failures, 0 errors, 0 skips


If you still can't get it to work, please file a bug. This is no the 
right forum for minitest support.

Well, it works when I run the spec via `ruby spec/...`.
But fails with
`rake`.

Actually I'm running into this with the project I'm trying with
`Hoe`.
Since you said this is not the place for such issue, I've posted
this issue at https://github.com/seattlerb/hoe/issues/30

Can you take a look into that?
