In an environment where the test basis is continuously changing, it is recommended to specify test conditions at a detailed level in order to achieve a better maintainability.

The specification of test conditions at a detailed level can be effective when no formal requirements or other development work products are available.

The specification of test conditions at a detailed level can require the implementation of an adequate level of formality across the team.

For system testing, the specification of test conditions at a detailed level, carried out early in the project as soon as the test basis is established, can contribute to defect prevention.
