The extent of testing required for a software product or feature depends on several factors that influence the level of quality and risk involved in delivering or deploying it. Some of these factors are:

• Budget to do testing: This factor indicates how much money is available or allocated for conducting the test activities, which affects the scope, depth, duration, and resources of testing.
• Time available to do testing: This factor indicates how much time is available or allocated for conducting the test activities, which affects the schedule, frequency, speed, and coverage of testing.
• Level of risk of the product or feature: This factor indicates how much impact or harm a failure or defect in the product or feature can cause to the users, customers, stakeholders, or environment, which affects the priority, intensity, complexity, and rigor of testing.
• Complexity of the product or feature: This factor indicates how difficult or challenging it is to understand, design, implement, or maintain the product or feature, which affects the effort, skill, technique, and tool required for testing.

A particular tester involved in testing is not a deciding factor in determining the extent of testing required because it does not affect the quality or risk level of the product or feature being tested. Rather, it is an outcome or consequence of deciding how much testing is needed based on other factors such as budget, time, risk, and complexity. You can find more information about determining the extent of testing in Software Testing Foundations: A Study Guide for the Certified Tester Exam, Chapter 2, Section 2.12.

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

Component integration testing is the process of testing the interactions between different components of a system. It should always be done before system testing, which is the process of testing the system as a whole. Integration testing can reveal defects in the interfaces and interactions between components, which can affect the functionality and performance of the system. System testing can reveal defects in the system requirements, design, and behavior, which can affect the quality and usability of the system. Therefore, it is logical to perform integration testing before system testing, to ensure that the components work together correctly before testing the system as a whole.
