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

This works, because the examples clear the stubs by resetting the stubs Array which is injected into the stubbed or mocked class at the end of the example.

Here is a test for this behavior in rspec:
