Software testing is an important activity in the software development life-cycle. In an earlier study in 2009, we reported the results of a regional survey of software testing practices among practitioners in the Canadian province of Alberta. To get a larger nationwide view on this topic (across Canada), we conducted a newer survey with a revised list of(More)
This paper presents a model-driven, stress test methodology aimed at increasing chances of discovering faults related to network traffic in distributed real-time systems (DRTS). The technique uses the UML 2.0 model of the distributed system under test, augmented with timing information, and is based on an analysis of the control flow in sequence diagrams.(More)
Software organizations have typically de-emphasized the importance of software testing. In an earlier study in 2004, our colleagues reported the results of an Alberta-wide regional survey of software testing techniques in practice. Five years after that first study, the authors felt it is time to replicate the survey and analyze what has changed and what(More)
Genetic algorithms (GAs) have been applied previously to UML-driven stress test requirements generation with the aim of increasing chances of discovering faults relating to network traffic in distributed real-time systems. However, since evolutionary algorithms are heuristic, their performance can vary across multiple executions, which may affect robustness(More)

In a previous work, we reported and experimented with a stress testing methodology to detect network traffic- related real-time (RT) faults in distributed real-time systems (DRTSs) based on the design UML models. The stress methodology, referred to as time-shifting stress test methodology (TSSTM), aimed at increasing chances of discovering RT faults(More)
There is an increasing demand for Multi-Agent Systems (MAS) in the software industry. In order to bring MAS to the main stream of commercial software development, the behavior of MAS must be monitored and verified against the risk of unwanted emergent behaviors including deadlocks. In this paper, we introduce a methodology for efficient monitoring of MAS to(More)
