TESSY – The powerful test tool

With TESSY you can carry out automated, dynamic module and unit tests of embedded software – while determining the degree of code coverage at the same time. These tests are required, for example, for certifications according to the DO-178, IEC 61508 or ISO 26262 standards.

New version available: TESSY 4.3 is now available for download . A brief overview and description of the new features can be found here .

The classification tree editor (CTE) provides a method for systematic test case specification. The classification tree method is used for this. CTE is part of TESSY.

TESSY and CTE are products from Razorcat Development GmbH, based on technology from the software research laboratory of the former Daimler-Benz AG in Berlin. Take a look at the testimonials from our customers with TESSY.
