“…However, this work focuses on non-transactional web services. In our previous works we devised a general framework for testing web services transactions using risk-based testing approach and taking into account individual participants such as executor [6,12,42]. In this paper we focus on the overall testing of WS Transaction at different dimensions.…”

“…The management of transactional activities complicates the business logic of web services as their execution requires careful coordination, accounting for faulttolerance, correct process termination and cancelation, without undesirable consequences at any stage of the execution. Numerous models and protocols have been developed for WS transactions which include Business Transaction Protocol (BTP) [3], Web Services Business Activity (WS-BA) [4] and Web Services Transaction Management (WS-TXM) [5], among others [6].…”

“…Fourth, individual behaviours (e.g., states and transitions) and relationships (e.g., execution order and flow) of services taking part in WS transactions cannot be easily determined. This is due to the fact that such services are heterogeneous and autonomous and thus they have different behaviours and relationships among their activities [6,9]. In summary, testing of WS transactions involves different challenges due to the complex nature of the environment, distinct behaviours of individual services, the relationships between services, the sharing of data and the consequential risk of data inconsistency.…”

“…The criteria define three dimensions; Level, Feature and Depth. The Level dimension defines the granularity level of testing, i.e., testing WS transactions at different levels such as activity (web service) level [6], nested subtransaction or overall transaction level. The Feature defines the source used to identify the situations to be tested (test conditions).…”

Web services (WS) transactions are important in order to reliably compose distributed and autonomous services into composite web services and to ensure that their execution is consistent and correct. But such transactions are generally complex and they require longer processing time, and manipulate critical data. Thus various techniques have been developed in order to perform quality assessment of WS transactions in terms of response time efficiency, failure recovery and throughput. This paper focuses on the testing aspect of WS transactions -a key issue that has not been examined in the literature. Accordingly it proposes multi-dimensional criteria for testing the WS transactions. The proposed criteria have the potential to capture the behaviour of WS transactions and to analyze and classify the possible (failure) situations that effect the execution of such transactions. These criteria are used to generate various test cases and to provide (WS transactions) tester with flexibility of adjusting the method in terms of test efforts and effectiveness. The proposed criteria have been designed, implemented and evaluated through a case study and a number of experiments have been performed. The evaluation shows that these criteria have the capability to effectively generate test cases for testing WS transactions as well as enable tester to decide on the trade-off between test efforts and the quality.

The ubiquitous nature of the World Wide Web (WWW) coupled with the flexibility and agility associated with Software Services is one of the primary contributing factors in the development and deployment of intelligent (Software) e-services. The applications of these intelligent e-services span a number of domains such as manufacturing, transportation, and health. The aim of this special issue (SI) is to present some of the cutting-edge research done in this area. In response to the call-forpapers for this SI, more than 40 submissions were received. After thorough peer-review process, which spanned multiple rounds, six papers were selected.The first paper of this special issue, authored by Casado et al.[1], proposes an abstract web-services transaction model. The advantage of this abstract transaction model is that various specific transaction models can be derived from it. The authors validate the proposed abstract transaction model and conclude that their approach can be used to define different test cases in order to test the reliability and failures of different Web Services (WS) Transaction standards.The second paper of this special issue, authored by Flahive et al.[2], proposes a dynamic methodology for reusing, extracting, and updating ontology in a semantic grid environment. Mathematical formulations covering various aspects of ontology extraction and updating have been proposed. A case study based on the Unified Medical Language System ontology is used for validation of the proposed methodology.The third paper of this special issue, authored by Kołodziej et al.[3], proposes three different genetic algorithms (GA)-based energy-aware scheduling methods in computational grids. The proposed approach makes use of two parameters, namely, dynamic voltage and frequency scaling model for modeling the overall grid energy usage. For validation purposes, the performance of the three GA-based approaches was tested under various parameters. The results demonstrate the robustness of the proposed GA-based schedulers in optimizing the energy usage of the grid clusters.The fourth paper of this special issue addresses an interesting decision-making problem in distributed environments-bilevel decision making. This paper, authored by Lu et al. [4], outlines a set of rules for bilevel decision making. The authors use a case study to demonstrate the validity and applicability of the proposed rule-based approach. They additionally carry out experiments to demonstrate the effectiveness of the proposed method in finding a solution to a bilevel decision problem.The fifth paper of this special issue proposes an intelligent profiling-based task scheduling approach for multicore network processors. A key objective of the proposed approach by Tang et al. [5] is to optimize the system throughput under a given set of system parameters. In the past few years, various web-based applications that leverage multicore processors have emerged. The proposed approach has been validated by implementing it on the Intel IXP network processor.
