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

ruby-talk
1

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 is my `spec/helper.rb` file:

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

   class MiniTest::Spec
     include MiniTest::Assertions
   end

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

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

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 capture_io of minitest not working with minitest/spec · Issue #30 · seattlerb/hoe · GitHub

Can you take a look into that?
