e-testing has developed a comprehensive modular approach to testing, based on testing best practices, approved by the Information Systems Examinations Board (ISEB) - a division of the British Computer Society. The approach has been designed to limit the risk, prior to exposing a system for live use. e-testing’s methodology is: 

1. the discovery of flaws
2. the checking of design limits
3. the demonstration of system and program behaviour
4. demonstrating that systems do what is expected
5. demonstrating that systems do not do what is not expected
6. demonstrating that systems are ‘fit for purpose’

Exhaustive testing on anything more than the smallest system is impossible. To do exhaustive testing would mean that every path through the software and every enter-able data value under all possibilities and conditions would be tested. e-testing’s methodology allows for a more benefit based testing approach tailored to client’s specific requirements.
