Rspec test

gistfile1.rb

require 'rspec'

module Dog
  def self.bark
    "Woof!"
  end
end

describe "Rspec re-setting stubs on classes" do
  it "should return 'Woof!'" do
    Dog.bark.should == 'Woof!'
  end

  it "should return a stubbed value" do
    Dog.stub(:bark).and_return('Bow wow')
    Dog.bark.should == 'Bow wow'
  end

  it "should not reset the stub since it's not something that will be re-loaded between examples" do
    Dog.bark.should == 'Woof!'
  end
end

Here is a test for this behavior in rspec:
