Abstract

In this work aspects of testing numeric programs for automatic result verification will be discussed. An outline of a test environment for analysing numeric programs based on symbolic program trace will be introduced, which supports soure, code inspection, test data generation and input data set classification. Applying the test tool during the whole software life cycle a data base of input/output relations will be created, which allows to guarantee functionality of a product related to the tested data. In this way, the effort invested for testing and analysing of numeric software can be saved and its reliability can be improved.

Zusammenfassung

In dieser Arbeit werden Aspekte des Testens numerischer Programme zur automatischen Ergebnisverifikation diskutiert. Dabei wird ein Grundgerüst für eine Testumgebung zur Analyse numerischer Programme vorgestellt, welche symbolische Programmausgabe verwendet. Diese unterstützt die Inspektion von Programmtexten, die Ermittlung von Testdaten und die Klassifizierung von Eingabedaten. Wird das Testwerkzeug während der gesamten Lebensdauer eines Programmes eingesetzt, entsteht eine Datenbank aus Ein-/Ausgaberelationen, welche es erlaubt die Funktionalität eines Produktes bezüglich der getesteten Daten zu garantieren. Auf diese Art kann der investierte Aufwand für das Prüfen und das Analysieren von numerischer Software gesichert werden und deren Zuverlässigkeit kann verbessert werden.
