Synthesis of distributed testers from true-concurrency models of reactive systems

Claude Jard
2003 Information and Software Technology  
Automatic synthesis of test cases for conformance testing has been principally developed with the objective of generating sequential test cases.  ...  König, we propose to use a true-concurrency model based on graph unfolding.  ...  In general, to reduce the complexity, one extracts only one test case using some heuristics.  ...

A Novel Approach for Deriving Test Scenarios and Test Cases from Events

Sandeep K. Singh, Sangeeta Sabharwal, J.P. Gupta
2012 Journal of Information Processing Systems  
Test cases that use events are an apt choice for these types of systems.  ...  Test coverage criterion and an algorithm are designed using these models to generate event sequence based test scenarios and test cases.  ...  In [55] , both use case and state diagrams are used for generating system-level test cases. In [56] authors have transformed Use Cases to a UML state model to generate test cases.  ...

Test Cases Generation from UML Activity Diagrams

Hyungchoul Kim, Sungwon Kang, Jongmoon Baik, Inyoung Ko
2007 Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing (SNPD 2007)  
This paper proposes a method to generate test cases from UML activity diagrams that minimizes the number of test cases generated while deriving all practically useful test cases.  ...  This conversion is performed based on the single stimulus principle, which helps avoid the state explosion problem in test generation for a concurrent system.  ...  By reducing the number of test cases for concurrent system testing while keeping all practically useful test cases, we can save cost and time in software development without compromising quality of the  ...

Conformance Relations for Labeled Event Structures [chapter]

Hernán Ponce de León, Stefan Haar, Delphine Longuet
2012 Lecture Notes in Computer Science  
We propose a theoretical framework for testing concurrent systems from true concurrency models like Petri nets or networks of automata.  ...  The underlying model of computation of such formalisms are labeled event structures, which allow to represent concurrency explicitly.  ...  The only advantage of using labeled event structures as a specification formalism for testing remains in the conciseness of the concurrent model with respect to a sequential one.  ...

Concurrent Defects and Test Coverage Criteria

Bidush Kumar Sahoo, Mitrabinda Ray
2016 Journal of Software  
The processes usually work together by conversing using variables or message passing. So, testing a concurrent program is complex for its non determinism behavior.  ...  The paper deals with several coverage criteria for testing concurrent programs.  ...  Structural criteria use the code, the accomplishment and structural features of the program for selecting test cases.  ...

Model-based testing for concurrent systems: unfolding-based test selection

Hernán Ponce de León, Stefan Haar, Delphine Longuet
2014 International Journal on Software Tools for Technology Transfer (STTT)  
In order to test such concurrent systems, we choose to use Petri nets as specifications and define a concurrent conformance relation named co-ioco.  ...  Model-based testing has mainly focused on models where concurrency is interpreted as interleaving (like the ioco theory for labeled transition systems), which may be too coarse when one wants concurrency  ...  However, under such an assumption, controllability of test cases must be ensured during their construction.  ...
