Software Testing Procedure

A good test effort is driven by questions such as:
How could this software break?
In what possible situations could this software fail to work predictably?
Software testing challenges the assumptions, risks, and uncertainty inherent in the work of other disciplines, and addresses those concerns using concrete demonstration and impartial evaluation.
Testing focuses primarily on evaluating or assessing product quality, which is realized through the following core practices:
Find and document defects in software quality.
Advise on the perceived software quality.
Validate and prove the assumptions made in design and requirement specifications through concrete demonstration.
Validate that the software product works as designed.
Validate that the requirements are implemented appropriately.
