RSpec1.0.0を入れてみた

インストールは簡単。

gem install rspec

ドキュメントを写経してみた

# officer_spec.rb
require 'officer'

describe "All Employees", :shared => true do
  it "should be payable" do
    @employee.should respond_to(:calculate_pay)
  end
end

describe "All Managers", :shared => true do
  it_should_behave_like "All Employees"
  it "should be bonusable" do
    @employee.shoud respond_to(:apply_bounus)
  end
end

describe Officer do
  before(:each) do
    @employee = Officer.new
  end

  it_should_behave_like "All Managers"
  
  it "shoud be optionable" do
    @employee.should respond_to(:grant_options)
  end
end

# officer.rb
class Officer
end
