Topic: How Can I say that My Software is Correct?

Message

This is a typical question coming to the mind of every programmer / tester. However to get an answer for it, we must try to understand as to how the software can fail. Failure of a piece of software is generally implied as its non-conformance to the requirements. However software failure can be due to many faults, few of which are given below.

Error or incompleteness in the requirements 
Difficulty in implementing the specification in the target environment 
Faulty system or program design 
Defects in the code 
In view of the variety of faults mentioned above, it is evident that testing cannot be seen as an activity, which will start after the coding phase. In fact software testing is an activity which encompasses the entire development life cycle. Our aim must be to test a program to demonstrate the existence of a fault.
