Consider the following statements regarding Performance Efficiency Testing: A) Static Analysis tools can analyze code to identify performance bottlenecks B) Code reviews are an effective way of detecting performance issues C) Scalability and Load testing are usually performed during the System test level D) Performance test execution cannot begin until a production-like environment is available Which TWO of these statements are TRUE?

Answer options

A: a and b Correct answer

B: a and c Correct answer

C: b and c

D: c and d

Correct Answer:

A. a and b; B. a and c

Explanation

Statements A (Static Analysis can identify performance issues) and B (Code reviews effectively detect performance bottlenecks) are true, supporting proactive measures in performance efficiency testing.

Why Incorrect

C. Scalability and Load testing is typically performed at different testing levels, not exclusively at System test.
D. Performance testing can often commence in staging environments before a production-like setup is available, depending on the context.
