1. System Testing

AP/CSE,
Sri Vidya College of Engineering & Technology,
Virudhunagar
2. ⢠Entire system is tested as per the
requirements.
⢠System testing falls within the scope of black
box testing.
⢠System testing is performed on the entire
system in the context of a Functional
Requirements and/or a System
Requirement Specification (SRS).

4. 1. Recovery Testing
ď Forces the software to fail in different conditions
and verifies that recovery is properly performed.
ď Many computer system recover from faults and
resume processing within a prespecified time.
ď If recovery requires human intervention, the
Mean Time to Repair (MTTR) is evaluated to
determine whether it is within acceptable limits.
5. 2. Security Testing
ď Attempts to verify that protection
mechanisms built into a system.
ď Any computer based system can
manages sensitive information or
causes actions that can improperly
harm individuals is a target for
illegal penetration.
ď Ex: Hackers
ď Legal Penetration : authorized
system designer
ď Illegal Penetration : Hacker
6. 3. Stress Testing
⢠Also known as âEndurance
(patience) Testingâ.
⢠Evaluate system performance
when it is stressed for short period
of time.
⢠Check the program with abnormal
situations.
Stress testing situations:
⢠Generate 10 interrupt per second
⢠Increase the input rate
⢠Request maximum resource
7. Sensitivity Testing
⢠Variation of stress testing technique is
sensitivity testing
⢠Attempts to uncover data combinations
within valid input classes that may cause
instability processing.
8. 4. Performance Testing
⢠Check whether the system meets
the non functional requirements
identified in the SRS.
⢠Considered as â Black Box testingâ
⢠Test the Run Time Performance of
software
⢠Also coupled with stress testing.
⢠Required both hardware and
software instrumentation to do this
testing.
