Risk-based testing in Testing Fundamentals - Cheat Sheet & Quick Revision

What is Risk-based testing?

Risk-based testing is a testing approach where tests are prioritized based on the risk of failure and its impact. It focuses on testing the most important and risky parts of the software first.

Why do we use risk-based testing?

We use risk-based testing to make the best use of limited testing time and resources by focusing on areas that could cause the most harm if they fail.

beginner

Name two key factors considered in risk-based testing.

The two key factors are:

• Likelihood of failure (how likely a problem is)
• Impact of failure (how bad the problem would be)

beginner

How does risk-based testing help in real-life projects?

It helps teams focus on testing the most critical features first, reducing the chance of serious bugs reaching users and saving time by not testing low-risk areas extensively.

beginner

What is a simple example of risk-based testing?

Imagine testing a banking app: testing money transfer features is high risk because errors can cause big losses, so these get tested first. Features like changing the app theme are low risk and tested later.

What does risk-based testing prioritize?

A Testing features with the highest risk first

B Testing features in alphabetical order

C Testing only the new features

D Testing features randomly

Risk-based testing focuses on testing the parts of the software that have the highest risk of failure and impact.

Which two factors are used to assess risk in risk-based testing?

A Number of users and code size

B Cost and time

C Likelihood of failure and impact of failure

D Test coverage and test speed

Risk is assessed by how likely a failure is and how bad the failure would be.

Why is risk-based testing useful when time is limited?

A It tests everything equally

B It focuses on the most important risks first

C It skips testing completely

D It tests only the easiest features

Risk-based testing helps use limited time wisely by focusing on the most risky parts first.

In risk-based testing, what happens to low-risk features?

A They are tested more than high-risk features

B They are tested first

C They are ignored completely

D They are tested last or less thoroughly

Low-risk features are tested later or with less effort to save resources.

Which of these is an example of a high-risk feature in a shopping app?

A Adding items to the shopping cart

B Reading the terms and conditions

C Viewing the help page

D Changing the app background color

Adding items to the cart is high risk because errors here affect purchases and revenue.

Explain what risk-based testing is and why it is important.

Think about how you decide what to test first when you have limited time.

Describe how you would decide which features to test first using risk-based testing.

Consider what could go wrong and how bad it would be.
