Automation Testing Performance and Load Testing 2

Question 1

What does the term 'virtual user' (VU) mean in performance testing?

Accepted Answer

A simulated user executing a test script concurrently with other simulated users

Answer

Virtual users (VUs) are concurrent simulated users that execute test scripts simultaneously to generate load on the target system.

Question 2

What is a 'ramp-up period' in a load test?

Accepted Answer

The time to gradually increase virtual users to the target load level

Answer

A ramp-up period gradually adds virtual users over time to reach peak load, avoiding sudden spikes that don't reflect real traffic patterns.

Question 3

What does 'soak testing' (endurance testing) measure?

Accepted Answer

System behavior and memory/resource usage under sustained load over a long period

Answer

Soak testing runs the system under normal load for an extended period (hours/days) to detect memory leaks, resource exhaustion, and degradation over time.

Question 4

In k6 performance testing, what language are test scripts written in?

Accepted Answer

JavaScript (ES6+)

Answer

k6 uses modern JavaScript (ES6+) for test scripts, making it accessible to developers already familiar with JS.

Question 5

What is the purpose of a baseline performance test?

Accepted Answer

Establishing a performance benchmark to compare future changes against

Answer

A baseline test captures current performance metrics so future changes can be compared against it to detect regressions or improvements.
