Hi arschles,

      I am go-lang beginner programmer 

     I am working on google compute engine API where createinstnace() method internally call authentication sign() function which print URL to visit and accept authentication code and generate and return oauth token which I used in  createinstnace to send authenticated request.

    link [3]

                  I really stuck how to write golang test when one function call other function internally. i.e. in this case createinstance() calls  sign() function.

  

     Thank You for your valuable time. I am looking forward to your reply.

 Regards,
