Which ONE of the following options represents a principle of performance testing?
A . The tests must be aligned with the defined expectations of different stakeholder groups, users In particular, system designers and operations staff
B . The tests can only be conducted, where resources allow, on complete systems and test environments that are representative of the production system.

Answer: C

Explanation:

Reproducibility is a fundamental principle of performance testing, ensuring that identical results are obtained when tests are repeated on an unchanged system. This principle is critical for verifying the reliability and consistency of performance test outcomes, allowing testers to confidently identify and address performance issues. ISTQB standards emphasize reproducibility to ensure that performance testing provides accurate and actionable insights.
