CTFL_Syll2018 Exam Dumps : ISTQB Certified Tester Foundation Level (Syllabus 2018)

Finding defects, gaining confidence about the level of quality and providing information, and preventing defects are all valid test objectives according to the ISTQB Foundation Level syllabus. Debugging the code is not a test objective, because debugging is the process of finding and fixing defects, which is done by developers, not testers3

 These are some of the factors that should be considered to determine whether enough testing has been performed. The exit criteria define the specific goals and requirements for testing completion. The budget limits the resources and time available for testing. The product’s risk profile indicates the areas of highest priority and impact for testing. Sufficient details of the system status allow decisions on whether further testing is needed or not. The other options are not relevant factors for determining enough testing.

The correct answer is A, as it states that the Wideband Delphi estimation technique is an example of the expert-based approach. The Wideband Delphi estimation technique is a method of estimating testing effort or duration by using a structured group process that involves multiple experts2. The experts provide their estimates independently and anonymously, then compare and discuss them until they reach a consensus2. This technique is an example of the expert-based approach, which is an approach that relies on the knowledge and experience of experts to estimate testing activities2. Option B is incorrect, as it states that the Wideband Delphi estimation technique is an example of the metrics-based approach. The metrics-based approach is an approach that uses historical data and mathematical formulas to estimate testing activities2. This approach does not involve experts or group processes. Option C is incorrect, as it states that burndown charts used in Agile development is an example of the expert-based approach. Burndown charts are graphical tools that show the amount of work remaining versus time in an Agile project2. They are used to monitor and control testing progress and quality. They are not examples of the expert-based approach, as they do not rely on experts’ opinions or estimates. Option D is incorrect, as it states that burndown charts used in Agile development is an example of the risk-based approach. The risk-based approach is an approach that uses risk analysis to prioritize and estimate testing activities2. This approach involves identifying and assessing risks based on their likelihood and impact. It does not involve burndown charts or Agile development. References: 2, Section 2.6
