What defines a test level?

A test level is defined by a group of organized test activities that correspond to a specific stage in the software development lifecycle. This encompasses the various testing phases, such as unit testing, integration testing, system testing, and acceptance testing. Each level focuses on different aspects of the software, such as individual components or the entire system, and involves distinct objectives, environments, and levels of detail regarding the testing performed.

This organized structure helps to ensure that testing is systematic and comprehensive, allowing teams to better manage and execute their testing efforts throughout the development process. By clearly defining test levels, organizations can facilitate effective communication about testing progress, identify risks at various stages, and ultimately deliver higher quality software.

In contrast to the other options, while test resources, strategies for test execution, and procedures for following up on test results are all important aspects of testing, they do not specifically define what a test level is. Test resources pertain to the tools and personnel involved, strategies focus on methodologies and techniques for execution, and procedures relate to the processes in place for managing test outcomes. Test levels, however, are distinctly about the categorization of testing efforts tied to different stages in development.
