Editing Test plan (section)

===Test coverage===

Test coverage in the test plan states what requirements will be verified during what stages of the product life. Test coverage is derived from design specifications and other requirements, such as safety standards or regulatory codes, where each requirement or specification of the design ideally will have one or more corresponding means of verification. Test coverage for different product life stages may overlap but will not necessarily be exactly the same for all stages. For example, some requirements may be verified during [[design verification test]], but not repeated during acceptance test. Test coverage also feeds back into the design process, since the product may have to be designed to allow test access.
