Which of the following is a characteristic of good testing in any life cycle model?

Good testing throughout any life cycle model is characterized by having specific test objectives for each test level. This approach ensures that testing is comprehensive and aligns with the goals set for that particular stage of development. Each test level, such as unit testing, integration testing, system testing, and acceptance testing, serves a distinct purpose and targets specific aspects of the software being developed. Having tailored objectives for each level allows testers to focus their efforts efficiently and effectively to verify that the software meets the defined requirements and quality standards before moving on to the next stage. This structured approach is crucial for identifying defects at the appropriate times and facilitates a systematic evaluation of the software.

In contrast, the other options do not capture the essence of good testing practices. Analysis and design of tests should ideally start earlier in the development process rather than waiting until development is complete. Having some development activities without corresponding test activities can lead to gaps in testing coverage, which is not favorable for quality assurance. Additionally, while collaboration between development and testing teams is valuable, not all document reviews necessarily involve the development team, as other stakeholders may also participate based on the context and nature of the review.
