“…Therefore, test isolation techniques (such as SUT duplication, tagging, SUT blocking, etc.) are required to separate testing processes from business processes [8,9,10]. In addition, testing activities have to be resource aware with the aim of minimizing execution nodes burdens while runtime tests are executed.…”

Abstract. This work focuses on testing the consistency of distributed and adaptable systems. In this context, Runtime Testing which is carried out on the final execution environment is emerging as a new solution for quality assurance and validation of these systems. This activity can be costly and resource consuming especially when execution environment is shared between the software system and the test system. To overcome this challenging problem, we propose a new approach to design a resource aware test architecture. We consider the best usage of available resources (such as CPU load, memory, battery level, etc.) in the execution nodes while assigning the test components to them. Hence, this work describes basically a method for test component placement in the execution environment based on an existing model called Multiple Multidimensional Knapsack Problem. A tool based on the constraint programming Choco library has been also implemented.

“…In addition, they did not concentrate on proposing a generic and platform independent test architecture that evolves when the system under test evolves too. Moreover, they are based on only one technique to isolate runtime tests in the aim of reducing the interference between business and test data except [8] which supports two kinds of test isolation techniques. These approaches mostly used a specific language framework such as Junit to write and execute tests.…”

“…First of all, the Listing 1 bellow outlines the adopted test configuration and highlights the different test components involved in this testing process. For editing and compiling the specified tests, we have used respectively the CL Editor (TTCN-3 Core Language Editor) and the TThree Compiler that are included in the TTworkbench basic tool 8 . The generated Jars are stored in the repository for further use and can be dynamically loaded during the execution when runtime testing is required to validate dynamic changes.…”

“…For this reason, a recent branch of work has demonstrated the interest of using the Runtime Testing as a new solution for the validation of the above systems [1][2][3][4][5][6][7][8]. They have focused on building specific test infrastructures, for instance based on the JUnit Framework.…”

Abstract. Today, adaptable and distributed component based systems need to be checked and validated in order to ensure their correctness and trustworthiness when dynamic changes occur. Traditional testing techniques can not be used since they are applied during the development phase. Therefore, runtime testing is emerging as a novel solution for the validation of highly dynamic systems at runtime. In this paper, we illustrate how a platform independent test system based on the TTCN-3 standard can be used to execute runtime tests. The proposed test system is called TT4RT: TTCN-3 test system for Runtime Testing. A case study in the telemedicine field is used as an illustration to show the relevance of the proposed test system.

Adaptive systems (ASs) and context-aware systems (CASs) are able to evaluate their own behaviour and to adapt it when the system fails to accomplish its goals or when better functionality or performance is possible. Ensuring the reliability of ASs and CASs is demanding because failures might have undesirable consequences. Testing ASs and CASs effectively is not trivial because of the inherent characteristics of these systems. The literature lacks a comprehensive review that provides a broad picture of the area; current reviews are outdated and incomplete. The objectives of this study are characterizing the state of the art in AS and CAS testing and discussing approaches, challenges, observed trends, and research limitations and directions. We performed a systematic literature review (SLR) and a thematic analysis of studies, reporting up-to-date, refined and extended results when compared with existing reviews. Based on 102 selected studies, we (i) characterized testing approaches by grouping techniques for ASs and CASs; (ii) updated and refined a characterization of testing challenges for ASs and CASs; and (iii) analysed and discussed research trends and implications for AS and CAS testing. There are recurring research concerns regarding AS and CAS testing. Examples are the generation of test cases and built-in tests. Moreover, we also identified recurring testing challenges such as context monitoring and runtime decisions. Moreover, there are some trends such as model-based testing and hybrid techniques and some little investigated issues like uncertainty and prediction of changes. All in all, our results may provide guidance for developers and researchers with respect to the practice and the future research on AS and CAS testing.
