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
Forces the software to fail in different conditions
and verifies that recovery is properly performed.
Many computer system recover from faults and
resume processing within a prespecified time.
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
Attempts to verify that protection
mechanisms built into a system.
Any computer based system can
manages sensitive information or
causes actions that can improperly
harm individuals is a target for
illegal penetration.
Ex: Hackers
Legal Penetration : authorized
system designer
Illegal Penetration : Hacker
6. 3. Stress Testing
• Also known as “Endurance
(patience) Testing”.
• 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 “ Black Box testing”
• Test the Run Time Performance of
software
• Also coupled with stress testing.
• Required both hardware and
software instrumentation to do this
testing.
