What should entry criteria ensure before moving to the next testing phase?

The correct answer focuses on the importance of ensuring that specific quality levels and performance benchmarks are achieved before moving to the next phase in the testing process. Entry criteria serve as a quality gate that helps teams ascertain whether the product meets the necessary standards for moving forward.

By confirming that quality levels and performance benchmarks are met, the testing team can ensure that the software behaves as expected and is stable enough for further testing or deployment. Meeting these criteria helps minimize the risk of significant defects surfacing later in the process, which can lead to increased costs and delays.

While the other options might be relevant to the overall testing process, they do not capture the essence of what entry criteria should establish. For instance, fully implemented features, completing documentation, and logging defects are certainly important, but they do not specifically address the quality assurance aspect that entry criteria are intended to focus on. Thus, ensuring that quality levels and benchmarks are achieved is crucial for the smooth progression of the testing lifecycle.
