ISTQB Advanced Level 4

Question 1

In the context of ISTQB Advanced Level, what is a 'test condition'?

Accepted Answer

A testable aspect of a component or system identified as a basis for test cases

Answer

A test condition is a specific aspect, feature, or scenario of the system under test that can be verified by one or more test cases.

Question 2

Which practice best supports the ISTQB principle that 'exhaustive testing is impossible'?

Accepted Answer

Using risk and priority to select the most valuable subset of tests

Answer

Since complete testing is infeasible, testers use risk-based prioritization and techniques like equivalence partitioning to maximize defect detection within constraints.

Question 3

A test manager is building a test team for a safety-critical avionics project. Which staffing consideration is MOST critical?

Accepted Answer

Including testers with domain knowledge and relevant certification

Answer

Safety-critical projects require testers with domain expertise and appropriate qualifications to understand complex regulations and identify domain-specific risks.

Question 4

What is the main advantage of model-based testing over scripted testing?

Accepted Answer

It enables automatic generation of test cases from a formal model of the system

Answer

Model-based testing uses a formal model to automatically generate diverse test cases, improving coverage and reducing manual test design effort.

Question 5

During test execution, a tester finds a defect that was previously marked as 'closed'. What is the CORRECT next step?

Accepted Answer

Reopen the original defect report with updated information

Answer

A defect that resurfaces after being closed should be reopened to preserve history, traceability, and metrics on defect resolution quality.
