Principles of Testing

There are various principles based on which the testing process is done.They are:

1.Testing shows presence of the defects

--Testing can only show the presence of the defects but never their absence
--After Testing do not say that
"There are no bugs or its working properly"
"This is a defect free or bug free applications"
--Always say that
"We did not find any bugs"
"We found some XXX bugs in that particular application"


2.Exhaustive Testing is Impossible

--Testing everything is impossible
--We can not take all the combination's to test the particular page and it is impossible
--We use test design techniques to test the most important test cases based on their risk and priority
--We use techniques like BV Analysis,Equivalence Partition,Pairwise testing etc.....

3.Early Testing

--Preparing Test Plan,Test Cases,Test Data as early as possible is good thing
--Early testing at the beginning of the application is a good thing to practise
--It's important to conduct reviews before the design document is created
