ISTQB Foundation 5

Question 1

Which of the following BEST defines 'test coverage'?

Accepted Answer

The degree to which specified coverage items have been exercised by tests

Answer

Test coverage measures how much of the defined coverage items (e.g., requirements, code statements, branches) have been exercised by the test suite.

Question 2

According to ISTQB, which of the following is a BENEFIT of early testing?

Accepted Answer

It reduces the cost of fixing defects found later in development

Answer

Defects found early in development are significantly cheaper to fix because fewer dependent artifacts and code changes are involved.

Question 3

Which testing approach examines the internal structure or code of a component without knowledge of its specifications?

Accepted Answer

White-box testing

Answer

White-box testing (also called structural or glass-box testing) bases tests on the internal implementation, code paths, and logic of the system.

Question 4

A tester groups all valid and invalid input values into classes where every value in a class is expected to be processed the same way. This technique is called:

Accepted Answer

Equivalence partitioning

Answer

Equivalence partitioning divides input data into partitions where all values within a partition are expected to trigger the same behavior.

Question 5

Which of the following statements about the V-model is TRUE?

Accepted Answer

Each development phase has a corresponding testing phase

Answer

The V-model maps each development phase (requirements, design, coding) to a corresponding test level (acceptance, integration/system, unit) on the right side of the 'V'.
