Thanks, that's the ticket!


For posterity here's what I got now. (I moved the $stdout stuff to the 
setup and teardown sections so I can use it for the rest of my 
specifies.)


$:.unshift File.join(File.dirname(__FILE__), '..', 'lib')
require 'dirs'
require 'stringio'

context "In an empty directory" do
  setup do
    @testing_dir = File.join(File.dirname(__FILE__), '..', '_test_temp')
    @test_dir = File.join(@testing_dir, 'test_dir')
    Dir.mkdir @testing_dir

    @stdout_orig = $stdout
    $stdout = StringIO.new
  end

  teardown do
    Dir.rmdir @testing_dir

    #@stdout_orig.puts "testy", $stdout.string, "testy end"
    $stdout = @stdout_orig
  end

  specify "we should be able to create any dir" do
    Dirs.create_dirs @test_dir
    Dir[@test_dir].should_not_be_empty
    Dir.rmdir @test_dir

    $stdout.string.grep(/Creating #{@test_dir}/).should_not_be_empty
  end

end


looks pretty nice now, I love it. This gives,


$ spec -f s test/dirs_spec.rb
In an empty directory
- we should be able to create any dir
