A Brief Meditation on the Essential Nature of Software Testing
Thus spoke the master: “Any program, no matter how small contains bugs”.

“A program without bugs would be an absurdity, a no one such If there were a program without any bug, then the world would cease to exist”. Geoffrey James, The Zen of Programming

What is Testing?
• Testing is the process of executing a program with the intent of finding errors

Testing – Why?
• Contribute to the delivery of higher quality software product • Undetected errors are costly to detect at a later stage • Satisfied users and to lower maintenance cost

Testing – How?
• By examining the users’ requirements • By reviewing the artifacts like design documents • By examining the design objectives • By examining the... [continues]
