Identify the correct definition of a load test

Which of the following best describes a load test in performance testing?

A Testing the system over an extended period to check for memory leaks and performance degradation.

B Testing the system by gradually increasing the load until it breaks to find the maximum capacity.

C Testing the system by suddenly increasing the load to observe how it handles unexpected spikes.

D Testing the system under normal and peak expected user loads to measure response times and throughput.

💡 Hint

Think about testing under expected user conditions.

Load testing measures how the system performs under expected normal and peak loads, focusing on response times and throughput.

Purpose of a stress test

What is the main goal of a stress test in performance testing?

A To find the system's breaking point by applying loads beyond normal capacity.

B To test system recovery after sudden load spikes.

C To verify system behavior under normal user load.

D To check system stability over a long duration.

💡 Hint

Think about pushing the system beyond limits.

Stress testing pushes the system beyond its normal limits to find the maximum capacity and observe failure behavior.

Difference between spike and soak tests

Which statement correctly distinguishes a spike test from a soak test?

A Spike test applies gradual load increase; soak test applies sudden load spikes.

B Spike test applies sudden high load for a short time; soak test applies normal load for a long time.

C Spike test checks system recovery after failure; soak test checks system under peak load.

D Spike test runs for days; soak test runs for seconds.

💡 Hint

Consider the duration and load pattern differences.

Spike testing involves sudden, sharp increases in load for a short period, while soak testing runs the system under normal load for a long time to check stability.

Identifying test types by scenario

A web app is tested by gradually increasing users until it crashes. Which performance test type is this?

A Stress test

B Load test

C Spike test

D Soak test

💡 Hint

Think about pushing the system to failure.

Gradually increasing load until failure is characteristic of stress testing to find the system's limits.

Choosing the right test for memory leak detection

Which performance test type is best suited to detect memory leaks and resource depletion over time?

A Spike test

B Stress test

C Soak test

D Load test

💡 Hint

Consider long duration testing.

Soak testing runs the system under normal load for a long time to detect issues like memory leaks and performance degradation.
