Impact of Performance on User Experience

Which non-functional quality aspect most directly affects how fast a user perceives a website to load?

A Security

B Maintainability

C Usability

D Performance

💡 Hint

Think about what makes a website feel slow or fast to a user.

Performance refers to how quickly a system responds. Slow performance makes users wait, harming their experience.

Reliability and User Trust

Why does reliability as a non-functional quality affect user experience?

A It guarantees the system never crashes or fails during use.

B It ensures the system looks attractive to users.

C It improves the speed of the system's response.

D It helps developers write code faster.

💡 Hint

Consider what happens if an app crashes often.

Reliability means the system works correctly without failures. If it crashes, users lose trust and stop using it.

Testing Accessibility Impact

Given a web app, which assertion best tests if accessibility (a non-functional quality) affects user experience?

Testing Fundamentals

assert page.has_accessible_labels() == True

A assert page.code_coverage > 80

B assert page.has_accessible_labels() == True

C assert page.security_level == 'high'

D assert page.load_time < 2

💡 Hint

Accessibility means users with disabilities can use the app easily.

Checking for accessible labels ensures screen readers can interpret the page, improving experience for disabled users.

Identifying Non-Functional Issue from Logs

Logs show frequent timeouts during peak hours. What non-functional quality is most likely causing poor user experience?

A Security breach

B Incorrect UI layout

C Performance degradation

D Missing documentation

💡 Hint

Timeouts usually mean the system is slow or overloaded.

Performance degradation during peak times causes slow responses or timeouts, frustrating users.

Designing a Test for Non-Functional Quality

You want to test how a mobile app behaves when network speed is very slow. Which testing approach best fits this non-functional quality?

A Network throttling during usability testing

B Load testing with many users

C Unit testing with mock objects

D Code review for security vulnerabilities

💡 Hint

Think about simulating slow internet to see user experience impact.

Network throttling simulates slow connections to test app behavior and user experience under poor network conditions.
