Seven principles of software testing are discussed: 1) Finding no defects does not mean no defects exist, 2) Exhaustively testing all scenarios is impossible so smarter testing is needed, 3) Testing efficiently saves time and money while making customers happy, 4) Defects tend to cluster together, 5) Test cases must be periodically updated to avoid outdated "pesticide paradox" tests, 6) Testing methods depend on the software context, 7) Absence of errors in testing does not prove the absence of defects in software.

1. Seven Testing Principles
By
Software Testing Tools

2. 1.Testing show presence of defects
● No defects found =/ No defects present

3. 2. Exhaustive testing is not possible
● All scenarios of software can’t be tested.
● Adopt smarter ways of testing

4. 3. Easy testing
● Save time.
● Save money.
● Make customer happy.

5. 4. Defect clustering
● Defects are present in cluster.

6. 5. Pesticide paradox
● Test cases should be update periodically.
● Review of test cases is important activity.

7. 6. Testing is context dependent
● Testing method/strategy is different for different
software’s

8. 7. Absence of error is fallacy
● Test only stable software’s defect.
