looking for a better test pattern for code passed in as blocks.

biscuit_block_testing.rb

# any help with the following would be awesome (@bvandgrift)

# here's the problem code (ish)
# testing the stuff in the 'chunkify' block sucks
def make_breakfast
  # ... 
  dough_for_biscuits = DoughBro.new
  dough_for_biscuits.chunkify do |chunk|
    if chunk.any?
      the_good_stuff = roll_dem_biscuits(chunky)
      # ...
    end
  end
  # ...
end

# the test, which seems clunky and inelegant
# using mocha

let(:reader) { TheProblemClass }
it "sends the good stuff down the road" do
  chunks = mock do
    stubs(:any?).returns(true, false)
    # expects biscuit stuff
  end    

  class BigFaker
    def chunkify
      proto_biscuits = grab_some_dough
      yield proto_biscuits
    end

    def grab_some_dough; []; end
  end

  BigFaker.any_instance.stubs(:make_biscuits).returns(chunks)

  DoughBro.expects(:new).returns(FakeReader.new)

  reader.make_breakfast    
end

# so this all works, but seems really clumsy.  is there a right way to
# do this?
