A Methodology To Test Instrument Software: An Application To the Diagnostic in Automotive Systems

Aim of this paper is to describe an original methodology for instrument software testing. A black-box approach is proposed to verify if the functional requirements of the software under test are fulfilled. In order to grant the reliability of the method, an experiment robust design technique is also adopted for the generation of the software input test sets. As an example of application the proposed methodology is applied to instrument diagnostic software for automotive systems. The results of validation tests carried out on data coming from a car engine measurement system, are reported and analyzed
