R. Kirner, S. Kandl:
"Test Coverage Analysis and Preservation for Requirements-Based Testing of Safety-Critical Systems";
ERCIM NEWS, 75 (2008), 75; S. 40 - 41.

The testing process for safety-critical systems is usually evaluated with code coverage criteria such
as MC/DC (Modified Condition/Decision Coverage) defined in the standard DO-178B, Software
Considerations in Airborne Systems and Equipment Certification (a de-facto standard for certifying
software in the civil avionic domain). For requirements-based testing techniques we work on
coverage metrics that are defined on a higher level of program representation (eg on the
requirements), and that are independent of a specific implementation. For that purpose we analyse
the relationship between existing definitions for structural requirement-coverage metrics and
structural code-coverage metrics. In addition, we work on techniques that preserve structural codecoverage
between different program-representation levels.
