Improving the accuracy of oracle verdicts through automated model steering

Gregory Gay, Sanjai Rayadurgam, Mats P.E. Heimdahl
2014 Proceedings of the 29th ACM/IEEE international conference on Automated software engineering - ASE '14  
We propose an automated steering framework that can adjust the behavior of the model to better match the behavior of the SUT to reduce the rate of false positives.  ...  The oracle-a judge of the correctness of the system under test (SUT)-is a major component of the testing process.  ...  Case study results indicate that steering improves the accuracy of the final oracle verdicts-outperforming both default testing practice and step-wise filtering.  ...

Steering model-based oracles to admit real program behaviors

Gregory Gay, Sanjai Rayadurgam, Mats P. E. Heimdahl
2014 Companion Proceedings of the 36th International Conference on Software Engineering - ICSE Companion 2014  
We therefore propose steering the model when used as an oracle, to admit an expanded set of behaviors when judging the SUT's adherence to its requirements.  ...  Behavioral models of such systems, often built for analysis and simulation, are appealing for reuse as oracles. However, these models typically provide an idealized view of the system.  ...  We also calculate the F-measure-the harmonic mean of precision and recall-in order to judge the accuracy of oracle verdicts.  ...

Oracles for Testing Software Timeliness with Uncertainty

Learning-Based Testing of Cyber-Physical Systems-of-Systems: A Platooning Study [chapter]

Karl Meinke
2017 Lecture Notes in Computer Science  
We consider the challenges faced, and some initial results obtained in an effort to scale up LBT to testing co-operative open cyber-physical systems-of-systems (CO-CPS).  ...  Learning-based testing (LBT) is a paradigm for fully automated requirements testing that combines machine learning with modelchecking techniques.  ...  So, a judicious choice of model accuracy, combinatorial test strategy and model abstraction can all be applied to improve the efficiency of learning and testing.  ...

A mapping study on testing non-testable systems

Krishna Patel, Robert M. Hierons
2017 Software quality journal  
The prevalence of the oracle problem has inspired the research community to develop several automated testing techniques that can detect functional software faults in such programs.  ...  The terms "Oracle Problem" and "Non-testable system" interchangeably refer to programs in which the application of test oracles is infeasible.  ...  We would also like to express our gratitude to all of the authors of the papers that were processed by this Mapping Study, who assisted us through email correspondence.  ...
