Effective error detection through unit tests in the embedded area

Unit tests are an indispensable part of the software development process today. They enable early error detection at module level and simplify subsequent integration. Targeted tests can be used to check error conditions that are either difficult to reproduce or not permitted in a system test. Since the introduction of the first unit test frameworks, FORTecH has consistently utilised these in the development process. In view of the diverse target environments in the embedded sector, we have developed our own lean and pragmatic framework for C and C++, which is based on the proven concepts of CppUnit.
