stub with substitute implementation

You can stub an implementation of a method (a.k.a. fake) by passing a block
to the stub() method.

Scenarios
stub implementation
Given
a file named "stub_implementation_spec.rb" with:
describe "a stubbed implementation" do
  it "works" do
    object = Object.new
    object.stub(:foo) do |arg|
      if arg == :this
        "got this"
      elsif arg == :that
        "got that"
      end
    end
    
    object.foo(:this).should eq("got this")
    object.foo(:that).should eq("got that")
  end
end
When
I run "rspec ./stub_implementation_spec.rb"
Then
the output should contain "1 example, 0 failures"
