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

Recall & Review

beginner

What is stress testing in software testing?

Stress testing is a type of performance testing where the software is tested beyond its normal operational capacity to see how it behaves under extreme conditions.

beginner

Why do we perform stress testing?

We perform stress testing to find the breaking point of the software and to ensure it fails gracefully without crashing unexpectedly.

How is stress testing different from load testing?

Load testing checks software behavior under expected maximum load, while stress testing pushes it beyond maximum load to test limits and recovery.

Name two common scenarios where stress testing is useful.

Stress testing is useful when expecting sudden spikes in users, like during sales events, and to test system recovery after failure.

beginner

What should testers observe during stress testing?

Testers should observe system crashes, slowdowns, error messages, data loss, and how the system recovers after stress is removed.

What is the main goal of stress testing?

A To check software under normal load

B To verify software installation

C To find software breaking point under extreme load

D To test user interface design

Stress testing aims to push software beyond normal limits to find where it breaks.

Which of these is NOT a focus of stress testing?

A System recovery after failure

B Behavior under extreme load

C Graceful failure handling

D Behavior under peak expected load

Behavior under peak expected load is load testing, not stress testing.

Stress testing helps to ensure the system:

A Never crashes under any condition

B Fails gracefully and recovers after extreme load

C Has no bugs in the code

D Loads quickly under normal use

Stress testing checks if the system fails gracefully and recovers well.

When is stress testing most useful?

A When expecting sudden user spikes

B Before software deployment to production

C During normal daily operations

D Only for UI testing

Stress testing is useful when sudden spikes in users or load are expected.

Which is a common result observed during stress testing?

A System crashes or slowdowns

B Faster response times

C Improved user experience

D No change in system behavior

Stress testing often causes crashes or slowdowns to identify limits.

Explain stress testing and why it is important in software testing.

Think about pushing a system harder than usual to see what happens.

Describe the difference between stress testing and load testing.

Compare normal peak vs. extreme overload.
