ISTQB Test Levels and Types 2

Question 1

Which test type evaluates quality characteristics such as performance, security, and usability?

Accepted Answer

Non-functional testing

Answer

Non-functional testing evaluates how well the system performs its functions, covering quality attributes like performance, security, reliability, and usability.

Question 2

What is the primary purpose of regression testing?

Accepted Answer

Verify that recent changes have not adversely affected existing functionality

Answer

Regression testing confirms that previously working software continues to work correctly after code changes, bug fixes, or configuration changes.

Question 3

Confirmation testing (re-testing) is BEST described as:

Accepted Answer

Re-executing failed tests to verify a specific defect has been fixed

Answer

Confirmation testing re-executes the specific test cases that previously failed to verify that the reported defect has been successfully resolved.

Question 4

Which of the following is an example of functional testing?

Accepted Answer

Verifying that a login form rejects invalid credentials

Answer

Functional testing evaluates what the system does — verifying specific behaviors against functional requirements, such as authentication logic.

Question 5

Structural testing (white-box testing) derives test cases primarily from:

Accepted Answer

The internal code structure, such as control flow or data flow

Answer

Structural testing uses knowledge of the system's internal implementation — code paths, branches, conditions — to design test cases.
