Strategies for Software Testing

Black box/Glass box/Gray box testing

*General testing principles:

Principle 1 - Testing shows presence of defects
Testing can show that defects are present but cannot prove that there are no defects.

Principle 2 - Exhaustive testing is impossible
Testing everything (all combinations of inputs and preconditions) is not feasible except for trivial cases.

Principle 3 - Early testing
Testing activities should start as early as possible in the SDLC.

Principle 4 - Defect clustering
A small number of modules contain most of the defects discovered during pre-release testing.

Principle 5 - Pesticide paradox
The test cases need to be regularly reviewed and revised

Principle 6 - Testing is context dependent

Testing is done differently in different contexts (safety-critical software is tested differently from e-commerce site)

Principle 7 - Absence-of errors fallacy

Finding and fixing defects does not help if the system built is unusable and does not fulfill the users' need and expectations.

* - from Syllabus for Cerified Tester

Make the software build to look as simple as possible Reduce maximum restriction for customer to use with complex data transaction in simple manner and easy.
