# Change:

  ruby_version_is '' ... '1.9' do
    it "raises a TypeError on a frozen array" do
      lambda { ArraySpecs.frozen_array << 5 }.should raise_error(TypeError)
    end
  end

  ruby_version_is '1.9' do
    it "raises a RuntimeError on a frozen array" do
      lambda { ArraySpecs.frozen_array << 5 }.should raise_error(RuntimeError)
    end
  end

# To:

  it "raises the appropriate error on a frozen array" do
    lambda { ArraySpecs.frozen_array << 5 }.should raise_error(mutating_frozen_object_error)
  end
