Ruby: Why are there no dots showing when I run tests using Test :: Unit?

Question

I play with Ruby Test::Unit::TestCase, and although my tests will run, pass, fail, etc. I do not see the points deduced for each test case. Is this the configuration I need to install, or the level of detail I need to specify?

I am running Ruby 2.1.0p0

For reference, here is the code I'm working with. This is from the Destroy All Software screencast, where the exercise is to build rspec from scratch (not all of this, of course):

Testing:

#test_spec.rb

require 'test/unit'
require_relative 'spec'


class TestDescribe < Test::Unit::TestCase
  def test_that_it_can_pass
    describe 'some thing' do
      it 'has some property' do
      end
    end
  end

  def test_that_it_can_fail
    assert_raise(IndexError) do
      describe 'some failing thing' do 
        it 'fails' do
          raise IndexError
        end
      end
    end
  end
end


class TestAssertion < Test::Unit::TestCase
  def test_that_it_can_pass
    2.should == 2
  end

  def test_that_it_can_fail
    assert_raise(AssertionError) do
      1.should == 2
    end
  end
end

And the code:

#spec.rb

def describe(description, &block)
  ExampleGroup.new(block).evaluate!
end


class ExampleGroup
  def initialize(block)
    @block = block
  end

  def evaluate!
    instance_eval(&@block)
  end

  def it(description, &block)
    block.call
  end
end


class Object
  def should
    DelayedAssertion.new(self)
  end
end

class DelayedAssertion
  def initialize(subject)
    @subject = subject
  end

  def ==(other)
    raise AssertionError unless @subject == other
  end
end


class AssertionError < Exception
end

Exit at startup with ruby test_spec.rb

Run options:
