Contact

✓ISO 26262 und IEC 61508 require such tests.

✓The Aerospace (DO178) does have more than

30 years of experience in doing this kind of

testing.

✓Software Unit Tests providing a 100%

structural source code Coverage, find software

bugs early.

✓To create the required documentation (Test

Cases, Test Procedures, Test Reports,

Traceability) for SW Unit Tests is costly and

takes a lot of time.

✓Therefore efficient ways to create these tests

are essential.
