Which of the following is usually identified by a performance test?
Performance tests primarily identify resource bottlenecks such as CPU saturation, memory leaks, network congestion, and database slowdowns.
Option B (Suitability issues) is a functional requirement concern, not a performance issue.
Option C (Learnability concerns) relates to usability testing, not performance.
Option D (Accessibility requirements) falls under compliance and usability testing, not performance testing.
Which of the following is a static performance test?
A static performance test is a non-execution-based review that analyzes system architecture, network configurations, and other elements that affect system performance before execution.
Option A (Usability test) is not a static performance test but rather a functional or UX evaluation.
Option B (Evaluation of testers' skills) is unrelated to performance testing.
Option D (Formal signature approval) is an administrative task and not a static test.
What is the primary purpose of a load generator?
A load generator is responsible for simulating virtual users and applying workloads to a system as defined by an operational profile. This allows testers to analyze how the system behaves under different load conditions.
Option A (Background load) is incorrect because load generators create simulated user interactions, not just background noise.
Option C (Record and analyze behavior) is the role of monitoring tools, not a load generator.
Option D (Support root cause analysis) is incorrect because root cause analysis is done after the load test, using monitoring tools.
Which of the following is a general principle of performance testing?
Performance testing is time-sensitive and must be designed to fit within the constraints of the project timeline. If performance tests take too long to execute, they may not be feasible within a given sprint or development cycle. The results should be reproducible, meaning the same test on an unchanged system should yield the same results (making option C incorrect). While stakeholder expectations are important, performance tests should be objective and based on defined benchmarks rather than subjective expectations (making option D incorrect).
How does a load management console aid performance testing?
A load management console is a tool that helps testers analyze and visualize test results, providing performance reports, graphs, and insights. This aids in understanding bottlenecks, response times, and throughput trends.
Option A (Simulating user behavior) is incorrect; load generators handle simulation.
Option B (Senior management monitoring) is not the primary role of a test console.
Option D (Emulating virtual users) is incorrect; that is the job of load injectors.
