Hello All, I am preparing for some manual testing interview questions and I want to know what is the pesticide paradox? How to overcome it? As I know it uses to test the software but I am not pretty much sure about this. Can anyone explain me?
Hi adisharma,
if we run the same tests over and over again, chances are high that these test cases will not find any new defects. “Pesticide paradox” means that it is very important to check the test cases regularly. New and different tests have to be written, covering different parts of the software or system, to find more errors.
Regards,

To overcome the pesticide paradox, software testers must continually write new and different tests to exercise different parts of the program and find more bugs. The code-and-fix model shown in Figure A is usually the one that project teams fall into by default if they don’t consciously attempt to use something else.
In order to overcome this “Pesticide Paradox”, the set of test cases needs to be regularly reviewed and revised. If required a new set of test cases can be added and the existing test cases can be deleted if they are not able to find any more defects from the system.
