#       URI::HTTP.uris = []
#       
#       @obj = MyClass.new
#     end
#     
#     def test_my_method
#       URI::HTTP.responses << 'some text open would ordinarily return'
#       
#       result = @obj.my_method
#       
#       assert_equal :something_meaninfgul, result
#       
#       assert_equal true, URI::HTTP.responses.empty?
#       assert_equal 1, URI::HTTP.uris.length
