Load testing concepts in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is load testing?

Load testing is a type of performance testing that checks how a system behaves under expected user loads. It helps find out if the system can handle the number of users or transactions it is designed for.

beginner

Why is load testing important?

Load testing is important because it ensures that software can handle real-world usage without crashing or slowing down. It helps avoid unhappy users and business losses.

What is a 'load profile' in load testing?

A load profile describes the pattern of user activity during a test, such as how many users access the system and what actions they perform over time.

intermediate

Difference between load testing and stress testing?

Load testing checks system behavior under expected loads, while stress testing pushes the system beyond its limits to see how it fails and recovers.

beginner

Name two common metrics measured during load testing.

Two common metrics are response time (how fast the system responds) and throughput (how many transactions it can handle per second).

What does load testing primarily measure?

A Code correctness

B System security vulnerabilities

C System behavior under expected user load

D User interface design

Load testing focuses on how the system performs when many users use it as expected.

Which of the following is NOT a goal of load testing?

A Test system recovery after failure

B Check system behavior under normal load

C Identify system bottlenecks

D Measure response times

Testing recovery after failure is part of stress testing, not load testing.

What is a 'load profile' used for in load testing?

A To define user activity patterns during the test

B To fix bugs found during testing

C To design the user interface

D To write test scripts

Load profiles describe how users interact with the system during the test.

Which metric shows how many transactions a system can handle per second?

A Response time

B CPU usage

C Error rate

D Throughput

Throughput measures the number of transactions processed per second.

Stress testing differs from load testing because it:

A Tests normal user load

B Pushes system beyond its limits

C Focuses on UI design

D Checks code syntax

Stress testing pushes the system beyond expected loads to find breaking points.

Explain what load testing is and why it is important.

Think about how many users use an app at the same time.

Describe the difference between load testing and stress testing.

One is normal use, the other is extreme use.
