What is the method used for measuring and managing session-based testing?

The correct answer is focused on session-based test management, which is a structured approach to testing that allows for flexibility and creativity while also providing a clear framework for measurement and organization. This method emphasizes managing the testing sessions by defining specific goals, tracking progress, and evaluating outcomes during and after the testing sessions.

By employing session-based test management, testers can effectively document their findings, monitor the time spent on each session, and ensure that all relevant aspects of the application are covered within the testing phases. This method not only aids in measuring the quality of testing but also enhances accountability and communication among team members, fostering an agile environment.

The other options, while relevant to testing concepts, do not encapsulate the comprehensive approach to managing and measuring the activities involved in session-based testing as effectively as session-based test management does. Other methods may focus on specific elements of testing or evaluation but lack the holistic management aspect that is pivotal for effective agile testing practices.
