✍️ Sample ISTQB Questions & Answers

1. In agile development, what testing activity typically occurs during a sprint review?
✓ Acceptance testing with stakeholders

Sprint reviews involve demonstrating working software to stakeholders, which often includes acceptance testing to validate delivered functionality.

2. In control flow testing, what is a 'predicate' node?
✓ A node where the flow splits based on a condition

A predicate node is a decision point in the control flow graph where execution can follow different paths based on a Boolean condition.

3. According to ISTQB, which of the following is an example of a 'project risk' (as opposed to a product risk)?
✓ Key test personnel may leave the project mid-cycle

Project risks threaten the test project's success, such as personnel turnover, while product risks relate to the software quality.

4. In the context of ISTQB, which factor most significantly determines whether a test tool will deliver expected benefits?
✓ The degree to which the tool is adopted and used correctly within the organization

Tool success depends primarily on organizational adoption and correct usage; even the best tool delivers no value if improperly used or ignored.

5. Which of the following activities is LEAST likely to benefit from test automation?
✓ Exploratory testing to investigate unexpected system behavior

Exploratory testing relies on human intuition, creativity, and real-time decision-making, which cannot be effectively replicated by automated tools.

6. When may the software development process begin to include testing?
✓ Once the software specifications are accepted

Testing should ideally begin as early as possible in the software development lifecycle, a principle known as 'Shift Left.' Once software specifications are accepted and finalized, test planning and test case design can commence, even before any code is written. This early engagement helps identify ambiguities, inconsistencies, or missing requirements, which are significantly cheaper to fix at this stage than later in the development process.
