Software Testing Performance & Load Testing

Question 1

What is the primary goal of performance testing?

Accepted Answer

Evaluate system speed, scalability, and stability under load

Answer

Performance testing evaluates how a system behaves in terms of speed, scalability, and stability under various load conditions, not functional correctness.

Question 2

Which type of performance test is designed to push the system beyond normal operational capacity to find its breaking point?

Accepted Answer

Stress test

Answer

Stress testing deliberately exceeds normal operational limits to identify the point at which the system fails or becomes unstable.

Question 3

Which metric measures the elapsed time from when a user sends a request to when they receive a complete response?

Accepted Answer

Response time

Answer

Response time is the interval between a user submitting a request and receiving the full response, making it a key user-experience metric.

Question 4

In performance testing, 'throughput' refers to which of the following?

Accepted Answer

The number of requests processed per unit of time

Answer

Throughput is the rate at which a system processes transactions or requests, typically expressed as requests per second or transactions per minute.

Question 5

What does a soak test (also called an endurance test) primarily evaluate?

Accepted Answer

System stability and potential memory leaks over an extended period

Answer

Soak testing runs the system under sustained load for a long duration to uncover memory leaks, resource depletion, and gradual performance degradation.
