ISTQB Updated CTAL-TM Exam Questions and Answers by eira

The next step after creating a custom automation tool is to test the tool itself. This is to ensure that the tool is reliable, functional, and compatible with the system under test. Testing the tool involves verifying its features, performance, usability, security, and stability. Testing the tool also helps to identify and fix any defects or issues before using it for theactual testing of the product. ISTQB Advanced Level Test Manager SyllabusTop 7 Automation Testing Tools to Consider References:

The best option to address this scenario is to leverage the development team to fill any knowledge gaps in the in-house tool. This option allows the test team to reuse the existing performance test suite and avoid the risks and costs of switching to a new tool or excluding performance testing altogether. The development team can provide support and guidance to the test team on how to use and modify the in-house tool, since it is written in the same programming language as the product itself. This option also preserves the intellectual property of the organization and does not expose the in-house tool to the open source community. ISTQB Advanced Level Test Manager SyllabusAdvanced Software Testing - Vol. 2 References:

Performance testing is the process of determining the speed, responsiveness, and stability of a system under a given workload1. Performance testing should be started as early aspossible in the software development lifecycle, preferably during unit and integration testing, to identify and resolve performance issues before they become costly or risky2. Starting performance testing early can also help to validate the performance requirements, design, and architecture of the system, as well as to optimize the performance testing strategy and scope3. Therefore, option A is the correct answer. Option B is incorrect because deferring the start of performance testing until all functional defects have been resolved can delay the detection and resolution of performance issues, increase the cost and effort of performance testing, and reduce the confidence and quality of the system4. Option C is incorrect because leveraging end users to do unit-level performance testing and automated tools for system-level performance testing can introduce inconsistency, bias, and inefficiency in the performance testing process, as well as compromise the reliability and validity of the performance test results. Option D is incorrect because requiring all performance tests to pass before starting functional testing can create unrealistic or unnecessary expectations, as well as hinder the progress and feedback of the functional testing activities. References: 1: ISTQB Glossary, Performance Testing 2: ISTQB® Certified Tester - Performance Testing (CT-PT)3 3: ISTQB® Performance Testing - TesterYou4 4: Performance Testing - ISTQB not-for-profit association : ISTQB - PERFORMANCE TESTING : Performance Testing - ISTQB not-for-profit association

In the IDEAL model, the Diagnosing step is where the success criteria are defined. This step involves understanding the current state and identifying gaps between the current and desired states. It sets the stage for creating action plans to address these gaps and defines the metrics for success.
