Guideline: In More Details - Determine The Test Basis (AST)

The individual test levels often make use of various sources for obtaining the product requirements, against which testing is carried out in the test level. For example, the acceptance test is often focused on requirements that are described at the level of, let’s say, business processes, whereas in the unit testing it is checked whether the technical requirements pertaining to a specific unit have been met. The test basis will therefore not be the same for all the test levels.
