The Best of Both Worlds: Model-Driven Engineering Meets Model-Based Testing

Authors: P. H. M. van Spaendonck and Tim A. C. Willemse

Published in: LIPIcs, Volume 279, 34th International Conference on Concurrency Theory (CONCUR 2023)

Abstract
We study the connection between stable-failures refinement and the ioco conformance relation. Both behavioural relations underlie methodologies that have gained traction in industry: stable-failures refinement is used in several commercial Model-Driven Engineering tool suites, whereas the ioco conformance relation is used in Model-Based Testing tools. Refinement-based Model-Driven Engineering approaches promise to generate executable code from high-level models, thus guaranteeing that the code upholds specified behavioural contracts. Manual testing, however, is still required to gain confidence that the model-to-code transformation and the execution platform do not lead to unexpected contract violations. We identify conditions under which also this last step in the design methodology can be automated using the ioco conformance relation and the associated tools.

Model-Based Testing for the Cloud

Authors: Antonia Bertolino, Wolfgang Grieskamp, Robert Hierons, Yves Le Traon, Bruno Legeard, Henry Muccini, Amit Paradkar, David Rosenblum, and Jan Tretmans

Published in: Dagstuhl Seminar Proceedings, Volume 10111, Practical Software Testing : Tool Automation and Human Factors (2010)

Abstract
Software in the cloud is characterised by the need to be highly adaptive and continuously available. Incremental changes are applied to the deployed system and need to be tested in the field. Different configurations need to be tested. Higher quality standards regarding both functional and non-functional properties are put on those systems, as they often face large and diverse customer bases and/or are used as services from different peer service implementations. The properties of interest include interoperability, privacy, security, reliability, performance, resource use, timing constraints, service dependencies, availability, and so on. This paper discusses the state of the art in model-based testing of cloud systems. It focuses on two central aspects of the problem domain: (a) dealing with the adaptive and dynamic character of cloud software when tested with model-based testing, by developing new online and offline test strategies, and (b) dealing with the variety of modeling concerns for functional and non-functional properties, by devising a unified framework for them where this is possible. Having discussed the state of the art we identify challenges and future directions.

Online Testing of Real-Time Systems Using UPPAAL: Status and Future Work

Authors: Kim G. Larsen, Marius Mikucionis, and Brian Nielsen

Published in: Dagstuhl Seminar Proceedings, Volume 4371, Perspectives of Model-Based Testing (2005)

Abstract
We present TUPPAAL --- a new tool for online black-box testing of real-time embedded systems from non-deterministic timed automata specifications. We describe a sound and complete randomized online testing algorithm, and describe how to implement it using symbolic state representation and manipulation techniques. We propose the notion of relativized timed input/output conformance as the formal implementation relation. A novelty of this relation and our testing algorithm is that they explicitly take environment assumptions into account, generate, execute and verify the result online using the UPPAAL on-the-fly model-checking tool engine. A medium size case study shows promising results in terms of error detection capability and computation performance.

Systematic Testing of Embedded Automotive Software - The Classification-Tree Method for Embedded Systems (CTM/ES)

Authors: Mirko Conrad

Published in: Dagstuhl Seminar Proceedings, Volume 4371, Perspectives of Model-Based Testing (2005)

Abstract
The software embedded in automotive control systems increasingly determines the functionality and properties of present-day motor vehicles. The development and test process of the systems and the software embedded becomes the limiting factor. While these challenges, on the development side, are met by employing model-based specification, design, and implementation techniques [KCF+04], satisfactory solutions on the testing side are slow in arriving. With regard to the systematic selection (test design) and the description of test scenarios especially, there is a lot of room for improvement. Thus, a main goal is to effectively minimize these deficits by creating an efficient procedure for the selection and description of test scenarios for embedded automotive software and its integration in the model-based development process. The realization of this idea involves the combination of a classical software testing procedure with a technology, prevalent in the automotive industry, which is used for the description of time-dependent stimuli signals. The result of this combination is the classification-tree method for embedded systems, CTM/ES [Con04]. The classification-tree method for embedded systems complements model-based development by employing a novel approach to the systematic selection and description of the test scenarios for the software embedded in the control systems. CTM/ES allows for the graphic representation of time-variable test scenarios on different levels of abstraction: A problem-oriented, compact representation, adequate for a human tester and containing a high potential for reusability, is gradually being transformed into a solution-oriented technical representation which is suited for the test objects' stimulation. The CTM/ES notation facilitates a consistent representation of test scenarios which may result from different test design techniques. The test design technique which this method is primarily based on, is a data-oriented partitioning of the input domain in equivalence classes. Secondary test design techniques are, for instance, the testing of specific values (or value courses) or requirement-based testing. A domain-specific application pragmatics in the form of agendas supports the methodical execution of individual test activities and the interaction of different test design techniques. The methodology description leads up to an effective test strategy for model-based testing, combining the classification-tree method for embedded systems with structural testing on the model level, and accommodating the different forms of representation of the test object during model-based development. Systems which have been developed in a model-based way can be tested systematically and efficiently by means of the CTM/ES and the tools based thereon, such as the classification-tree editor for embedded systems CTE/ES [CTE/ES], as well as the model-based test environment MTest [LBE+04, MTest].

Testing with Functions as Specifications

Authors: Pieter Koopman

Published in: Dagstuhl Seminar Proceedings, Volume 4371, Perspectives of Model-Based Testing (2005)

Abstract
In this paper we show that mathematical functions and logical expressions can very well be used as, partial, specifications. Reactive systems can be modelled by powerful extended state transition systems, that can be nondeterministic and can handle parameterized and infinite types for the inputs, outputs and states. These specifications can very concisely and directly be stated in a modern functional programming language. The test tool Gast is able to generate test data based on these specifications, execute the associated tests, and make a verdict fully automatically. Test data can be generated fully automatically, but can also be tailored in various high level ways, if that is desired. Advantages of this approach are that one specifies properties instead of instances of these properties, test data are automatically derived instead of manually, the tests performed are always up to date with the current specification, and testing is automatic (and hence fast and accurate).
