On-the-fly verification with stubborn sets [chapter]

Antti Valmari
1993 Lecture Notes in Computer Science  
A new on-the-fly verification method is presented. The method uses a generalization of Bilchi automata called "tester processes" for representing and detecting illegal behaviour.  ...  To reduce the number of states that are constructed the method applies the stubborn set theory in a new way. The method can be used in connection with the "Supertrace" memory-saving technique.  ...  Acknowledgements Part of this work was funded by the Technology Development Centre of Finland (TEKES).  ...

Determining the optical constants of read-write sliders during flying-height testing

Peter de Groot, Ara Dergevorkian, Tod Erickson, Russell Pavlat
1998 Applied Optics  
We describe an instrument that determines the optical constants simultaneously with flying height, using polarization interferometry.  ...  Flying-height testers for rigid disk drives employ a transparent glass substrate in place of the magnetic disk and use optical interferometry to measure the flight properties of the read-write slider.  ...  For this reason, the data-storage industry relies on optical testers for quantifying flying height in production and in the development of new designs. 1 Optical testers employ a rotating, transparent  ...

Introduction to Software Testing

Durgesh Raghuvanshi
2020 Zenodo  
It is the usual norm that software is considered of good quality if it meets the user requirements.  ...  This chapter introduces the subject of software testing by describing the activities of a test engineer, de ning a number of key terms, and then explaining the central notion of test coverage.  ...  One of the most important distinctions to make is between validation and verification.  ...

Accelerating Test Automation through a Domain Specific Language

Anurag Dwarakanath, Dipin Era, Aditya Priyadarshi, Neville Dubash, Sanjay Podder
2017 2017 IEEE International Conference on Software Testing, Verification and Validation (ICST)  
There are two key problems in the existing tools and methods for test automation - a) Creating an automation test script is essentially a code development task, which most testers are not trained on; and  ...  ATAP allows the creation of an automation test script through a domain specific language based on English.  ...  However, the manual testers found the verification statements (starting with the 'Then' keyword) difficult to interpret.  ...

Time Properties Verification Framework for UML-MARTE Safety Critical Real-Time Systems [chapter]

Ning Ge, Marc Pantel
2012 Lecture Notes in Computer Science  
This framework relies on a propertydriven transformation from UML architecture and behaviour models to executable and verifiable models expressed with Time Petri Nets (TPN).  ...  Meanwhile, it translates the time properties into a set of property patterns, corresponding to TPN observers. The observer-based model checking approach is then performed on the produced TPN.  ...  On the methodological side, we will experiment with other kind of properties, like the functional property, to improve the Property-driven approach to DSML (Domain Specific Modelling Language) model verification  ...
