CAD Testing & Debugging 3

Question 1

What is user acceptance testing (UAT)?

Accepted Answer

Testing performed by end users to validate the system meets their requirements

Answer

UAT is conducted by end users or clients to confirm the system meets their defined requirements before formal acceptance and release.

Question 2

What does a NullPointerException (or null reference error) typically indicate when debugging?

Accepted Answer

Code is attempting to use a reference variable that has not been initialized

Answer

A NullPointerException occurs when code dereferences a variable that points to null rather than a valid object instance.

Question 3

Which testing approach evaluates how a system behaves when pushed beyond its normal operational capacity?

Accepted Answer

Stress testing

Answer

Stress testing deliberately pushes a system beyond its designed load limits to observe failure behavior and identify breaking points.

Question 4

What is the primary purpose of static code analysis?

Accepted Answer

Examining source code without executing it to identify potential bugs and violations

Answer

Static code analysis inspects source code without running it, identifying potential bugs, security vulnerabilities, and style violations automatically.

Question 5

What is a 'smoke test' in the software development lifecycle?

Accepted Answer

A quick preliminary test to verify basic functionality before deeper testing begins

Answer

A smoke test is a shallow, rapid check of critical functionality to confirm a build is stable enough for more thorough testing.
