Final answer:
The valid testing objective is to validate if the test object meets user and stakeholder expectations. Starting tests late doesn't ensure quality, and testing can never guarantee the identification or absence of all defects. The correct answer is option B. To validate whether the test object works as expected by the users and other stakeholders.
Step-by-step explanation:
The statement that serves as a valid objective for testing is: 'To validate whether the test object works as expected by the users and other stakeholders'. This objective aligns with the purpose of testing, which is to ascertain that a product or system performs according to defined requirements and use cases. Testing should uncover defects or areas of improvement but cannot absolutely prove that all potential defects have been identified or that remaining defects will not cause any failures.
Starting tests as late as possible does not necessarily support the development of a good product, as early testing can identify issues before they become too complex to resolve efficiently. The purpose is not to prove that no defects remain or that they won't cause failures because it is often impractical to test all possible use cases and scenarios due to resource constraints. Therefore, rigorous and well-planned testing procedures that focus on key functionality and user requirements are critical. These procedures help to ensure that the product aligns with stakeholder expectations and performs as intended within the defined constraints and criteria. The correct answer is option B. To validate whether the test object works as expected by the users and other stakeholders.
