7. Static analysis cannot ____________
a) Enforce coding standards
b) Help in code understanding
c) Identify anomalies or defects in the code
d) Detect memory leaks
View Answer

Answer: d
Explanation: Memory leaks occur dynamically and hence, static analysis cannot identify them.

8. _______________ ensures the original fault has been removed.
a) Regression testing
b) Re-testing
c) Negative testing
d) Positive testing
View Answer

Answer: b
Explanation: Regression testing looks for unexpected side effects while retesting ensures the original errors are removed.

9. _____________ test cases are when random test cases are performed and equivalence partitioning is applied to those test cases.
a) Random
b) Static
c) Semi-random
d) Equivalent-random
View Answer

Answer: c
Explanation: It removes redundant test cases, thus giving semi-random test cases.

10. ______________ is normally used to evaluate a product to determine its suitability for intended use and to identify discrepancies.
