Answer Posted / samer desouky
The ISTQB define 7 testing principles, two of them are:
Defect Clustering, which means that some modules may
contain most of the defects discovered during pre-release
testing, or are responsible for the most operational
failures, which means focusing on the most defected area.
Pesticide paradox, means you need to updates your test s
after repeating over and over again, because eventually the
same set of test cases will no longer find any new defects.
