  def full_name
    "#{last_name} #{name}"
  end
end

describe Ninja do
  let(name) { "Kakashi" }
  let(last_name : String) { "Hatake" }

  subject { Described.new(last_name, name) }

  describe "#full_name" do
    it "returns full name" do
      subject.full_name.should eq("Hatake Kakashi")
    end

    context "when name change" do
      before { subject.name = "Sakumo" }

      it "returns full name" do
