Service Oriented Architectures (SOAs) are composed of distributed services that interact through standard interfaces, and evolve transparently to other services and users. Although such dynamicity makes SOA a promising architectural style, it prevents organizations from having complete knowledge of the SOA and of its (possibly untrusted) services. This constitutes an important restriction to the applicability...
Reflexion models are a conformance checking technique between high-level models and source code. I propose three changes to improve scalability of the technique and its ease of use in the context of an evolving software development project. First, express architectural rules as design tests that may be checked in a testing framework. Second, support semi-automated changes to the mapping between source...
Model-based software engineering is an increasingly applied method in producing software artifacts that is driven by model transformation. For example, Model-Driven Architecture (MDA) is an approach to develop software based on different models. Source code is generated automatically from these models. This makes model transformations the heart of MDA and other model-based software engineering approaches...
Testing Service Oriented Architecture applications is a challenging task due to the high dynamism, the low coupling and the low testability of services. Web services, a popular implementation of services, are usually provided as black box and using testing techniques based on implementation is limited. This paper presents an approach to support the use of the structural testing technique on web service...
In the Software Product Lines (SPL) context, where products are derived from a common platform, the reference architecture can be considered the main asset. In order to maintain its correctness and reliability after modifications, a regression testing approach based on architecture specification and code was developed. It aims to reduce the testing effort, by reusing test cases, execution results,...
The paper reports a new testing method working with state pattern designed software systems. The tests are performed in terms of symbolic execution aiming to identify conditions and values of some input parameters that violate assertions at runtime. The state based architecture of such systems allows a direct mapping of the methods to the transitions of the underlying finite state machine (FSM). In...
Methodology of automatic generation of test cases based on Model Driven Architecture is proposed, and its design and implementation have be done. The process of generating test cases is that a platform-independent model is converted into a platform-independent test model through level conversion, and the platform-independent test model is converted into the corresponding test cases through vertical...
Service-Oriented Architecture (SOA) fosters the development of loosely coupled applications. Web services have been favored as a promising technology to implement SOAs. Since web services are often involved in complex business processes and safety-critical systems, it is important that they are of high level of reliability. In this paper a strategy for event-based testing of web services is introduced...
Many computer systems and applications must be “non-stop” that is, provide continuous and uninterrupted services. Meanwhile, Service-Based Applications (SBAs) should be dynamic in terms of adap¬tability in order to operate and evolve in highly dynamic environments. Thus, in general, non-stop service-based applications require the ability to be updated without interruption. Flurry of researches on...
Since software systems become more and more complex, the efforts for developing, documenting and executing meaningful test cases increases. Testing is a vital, but time- and resource-consuming activity. To avoid running out of time or budget, new test methodologies had to be established in order to increase reliable, yet maintainable test scenarios. In the last years the Model-Driven idea matures...
The potential benefits of business agility, flexibility, and reuse associated with SOA are well known today. However, these benefits do not come without a cost of their own, particularly regarding security. The primary goal to make Web services widely accessible can also make them vulnerable. This paper examines the key challenges for securing service-oriented environments and identifies the important...
