Hitex Development Tools recently revealed that the TESSY tool for automated unit/module/integration testing of embedded software was re-qualified for safety-related software developing according to the IEC 61508:2010 and ISO 26262:2011 standards. The qualification was done by the T?V S?D and is valid since version V3.0.18 of TESSY.

The tool now fulfills the requirements for off-line support tools according to IEC 61508-3:2010. It was classified as being class T2. TESSY also meets the requirements of tool qualification according to ISO 26262-8 for all Automotive Safety Integrity Levels (ASILs). For the Tool Impact (TI) the value 2 was determined and the Tool Error Detection Level (TD) was assumed to have the value 3 resulting in value 3 for the Tool Confidence Level (TCL).

Tessy V2.9 already was qualified in December 2011. Its re-qualification became necessary with the release of the new major version, TESSY V3.0. The latest tool introduces comprehensive extensions of the functionality, such as the traceability of requirements to test cases.

This certificate eases the tool qualification process for TESSY users significantly, but does not make it trivial. The tool qualification stays in the responsibility of the user and needs complementary measures, for instance tests. To assist the user in such additional measures, an optional Tool Qualification Package (TQP) is provided. The package contains documents and test cases describing the tasks TESSY accomplishes during the testing process and rates these tasks with regard to safety-related projects. The test cases are especially designed to check the tasks relevant for safety-critical projects.
