Testing in the software development lifecycle in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of testing in the software development lifecycle?

Testing helps find and fix problems early to make sure the software works well and meets user needs.

beginner

Name two common types of testing done during the software development lifecycle.

Unit testing (checks small parts of code) and system testing (checks the whole software together).

intermediate

At which phase of the software development lifecycle should testing start?

Testing should start early, even during the requirements and design phases, to catch issues before coding.

intermediate

What is regression testing and why is it important?

Regression testing checks that new changes do not break existing features. It keeps software stable over time.

intermediate

How does automated testing help in the software development lifecycle?

Automated testing runs tests quickly and often, saving time and catching problems early without manual effort.

When should testing ideally begin in the software development lifecycle?

A After deployment

B Only after coding is complete

C During user training

D During the requirements phase

Testing should start early, even during requirements, to find issues before coding begins.

Which type of testing focuses on checking small parts of the code individually?

A Unit testing

B System testing

C Acceptance testing

D Performance testing

Unit testing checks individual pieces of code to ensure they work correctly.

What is the main goal of regression testing?

A Check if old features still work after changes

B Test new features only

C Test software speed

D Test user interface design

Regression testing ensures that recent changes do not break existing functionality.

How does automated testing benefit the development process?

A It slows down testing

B It requires more manual work

C It runs tests faster and more often

D It replaces all manual testing

Automated testing speeds up testing and allows frequent checks without extra manual effort.

Which phase is NOT typically part of the software development lifecycle where testing occurs?

A Design

B Marketing

C Maintenance

D Deployment

Marketing is outside the software development lifecycle phases where testing happens.

Explain why testing early in the software development lifecycle is beneficial.

Think about how fixing problems early is easier than later.

Describe the difference between unit testing and system testing.

Compare testing a single piece versus the entire product.
