Today’s information society means increasing levels of reliance from computer based systems. Failure of some of these applications on the field may have a tremendous financial impact and may even threaten human lives. Assuring that these systems respond appropriately to unusual or exceptional events requires more than traditional testing. Xception™ does it like none other.
In critical sectors, before deploying applications and systems, these must be subject of intensive testing in order to guarantee that the system and, particularly, built-in fault-tolerance mechanisms are working as expected. Assuring that the system responds appropriately to unusual or exceptional events requires more than traditional testing. Fault Injection is the answer to these new demands.
Xception™ is the software technology for software testing, certification, and dependability validation/evaluation used by space agencies around the world. Xception™ SWIFI approach relies on advanced debugging and performance monitoring hardware features, available in common processors, to inject faults and monitor the activation of errors and their impact on the target system. It is the clever usage of those hardware resources that brings the almost zero level interference in the system under test when compared with other approaches
Xception™ provides the ability to test systems in exceptional situations that may occur in the field, experiment worst failure scenarios, and spot weak-points in the system, proving feedback for correction or redesign.
Using the Xception™ fault injection technology, Verification and Validation (V&V) activities may be performed on 3rd party systems based on proprietary design and COTS parts. Those systems can be evaluated under realistic conditions with minimal intrusiveness and reliable validation of fault tolerance mechanisms.
