Which ONE of the following options represents a principle of performance testing?
SELECT ONE OPTION

  1. The tests must be aligned with the defined expectations of different stakeholder groups, users In particular, system designers and operations staff
  2. The tests can only be conducted, where resources allow, on complete systems and test environments that are representative of the production system.
  3. The tests must be reproducible. Identical results must be obtained by repeating the tests on an unchanged system.
  4. The tests must yield results that are both understandable and can be readily compared to the requirements desired by the technical team.

Answer(s): C

Explanation:

Reproducibility is a fundamental principle of performance testing, ensuring that identical results are obtained when tests are repeated on an unchanged system. This principle is critical for verifying the reliability and consistency of performance test outcomes, allowing testers to confidently identify and address performance issues. ISTQB standards emphasize reproducibility to ensure that performance testing provides accurate and actionable insights.



If George is testing in order to check the stability of a system for a specific period of time in an operational system context, what type of testing is MOST appropriate? SELECT ONE OPTION

  1. Endurance testing.
  2. Capacity testing.
  3. Spike testing.
  4. Load testing.

Answer(s): A

Explanation:

Endurance testing, also known as soak testing, evaluates the stability and performance of a system over an extended period under a significant load. This type of testing is designed to identify issues such as memory leaks, resource depletion, and other long-term stability problems that may not be evident in shorter testing durations. According to ISTQB guidelines, endurance testing is essential for ensuring that the system can maintain performance and stability over time, especially in operational contexts.



Associate each type of performance test (listed from 1 to 5) with part of a description that allows its characterization and/or identification (listed from A to E).
1. Endurance testing
2. Scalability testing
3. Capacity testing
4. Stress testing
5. Concurrency testing
1. Type of testing focused on the ability of a system to meet future efficiency requirements.

2. Type of testing used to evaluate a system's ability to handle reduced availability of resources.
3. Type of testing focused on the stability of the system over a specific time frame.
4. Type of testing used to determine the number of transactions a given system will support while still meeting established performance objectives.
5. Type of testing focused on the impact of situations where specific actions occur simultaneously.
SELECT ONE OPTION

  1. 1C-2D-3E-4B-5A
  2. 1B-2A-3D-4C-5E
  3. 1B-2E-3A-4D-5C
  4. 1C - 2A - 3D - 4B - 5E

Answer(s): C

Explanation:

The correct associations are based on the definitions of each type of performance testing:
1. Endurance testing: Focused on the stability of the system over a specific time frame. (B)
2. Scalability testing: Focused on the ability of a system to meet future efficiency requirements. (E)
3. Capacity testing: Used to determine the number of transactions a given system will support while still meeting established performance objectives. (A)
4. Stress testing: Evaluates a system's ability to handle reduced availability of resources. (D)
5. Concurrency testing: Focused on the impact of situations where specific actions occur simultaneously. (C)

In which activity of the testing process are specific test conditions identified for performance testing? SELECT ONE OPTION

  1. Test planning.
  2. Test monitoring and control.
  3. Test analysis.
  4. Test design.

Answer(s): C

Explanation:

In the testing process, specific test conditions for performance testing are identified during the Test Analysis phase. This phase involves reviewing and analyzing the test basis, such as requirements, architecture, and design, to identify the test conditions, which are the items or events of a component or system that could be verified by one or more test cases.
