Nowadays, web services play a major role in the development of enterprise applications. Many such applications are now developed using a service-oriented architecture (SOA), where microservices is one of its most popular kind. A RESTful web service will provide data via an API over the network using HTTP, possibly interacting with databases and other web services. Testing a RESTful API poses challenges,...
In this paper, a PXI-based avionics bus test system for ARINC 664 is developed using C# language and NI Measurement Studio. The system uses "Platform Invoke" technology to invoke the built-in functions in DLL files provided by the PXI-C664 board. The network configuration tool and avionics bus test tool are built in the system. The first tool aims to generate the AFDX end system configurations,...
REST Chart is a Petri-Net based XML modeling framework for REST API. This paper presents two important enhancements and extensions to REST Chart modeling - Hyperlink Decoration and Hierarchical REST Chart. In particular, the proposed Hyperlink Decoration decomposes resource connections from resource representation, such that hyperlinks can be defined independently of schemas. This allows a Navigation-First...
As primarily modular and distributed architectures, service-oriented architectures may impose new challenges in software evolution. Since web services evolve independently, this may cause disruptions to the proper function of consuming software. In this paper, we present \wsd, an Eclipse plug-in to support the evolution of service clients, including (a) identifying the differences between two service...
We present Dfuzzer, a fully automated tool for fuzz testing programs communicating via D-Bus. D-Bus is the prevalent modern mechanism for an inter-process communication in the GNU/Linux ecosystem. Programs receiving data over D-Bus should sanitize the inputs correctly as it may come from any application having access to the message bus. Unfortunately, it is often not the case as demonstrated by severe...
Speech synthesis is very popular topic and it's a research object of several scientists. This paper deals with modular speech synthesizer generally and text categorization module integrated into the concept of modular speech synthesizer. It consists of two main parts. The First part describes modular speech synthesizer in general. It explains its functions, purpose, idea, etc. The Second part is focused...
In this work, we present the process of identifying potential vulnerabilities in 6LoWPAN enabled networks through fuzzing. The 6LowPAN protocol has been designed by the IETF as an adaptation layer of IPv6 for Low power and lossy networks. The fuzzing process is build upon the Scapy packets manipulation library. It provides different mutation algorithms to be applied on 6LoWPAN protocol messages to...
While testing the software of communication network monitoring system, it is best to use real data to test the environment. However, in the lab environment, the resource is limited, and cannot mirror the data of real network totally. In order to fully complete test, we need to generate traffic following the real data that we captured in the real network to simulate the date in real network. Along...
Geospatial data, such as 2-D satellite images, 3-D image time-series, or 4-D climate/ocean data, provide important information for Earth Science System research. Standardized communication protocols, such as those established by Open Geospatial Consortium (OGC), help to achieve interoperability between clients and servers. To achieve real interoperability, conformance testing is required to test interface...
Delay and Disruption tolerant networking (DTN) embraces the concepts of occasionally-connected networks that may suffer from frequent partitions and that may be comprised of more than one divergent set of protocols or protocol families. Since DTN was conceived to relax most of the assumptions associated with Internet protocols, the most important of which is the availability of an end-to-end path...
By deeply studying the E-LOTOS standard and the XML language, this paper has analyzed the E-LOTOS text that is used to describe the protocol running mechanism, and has designed the structure of XML that is preserve the abstract test case, the file class supported by JAVA is used to parse the E-LOTOS text, and the adjacency FSM(finite state machine) is obtained meanwhile the FSM`s graph is drawn. Based...
We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably...
This paper describes a technique by which English prose protocol standards were transcribed into individually testable assertions and traced from original protocol specifications, to lists of requirements, to models and test cases, and finally into test logs and network captures. Annotating statements to make them stand alone, the handling of optional behavior, and using the requirements to guide...
In recent years Web-based systems have become extremely popular and, nowadays, they are used in critical environments such as financial, medical, and military systems. As the use of Web applications for security-critical services has increased, the number and sophistication of attacks against these applications have grown as well. For this reason it is essential to be able to prove that the target...
In order to improve the efficiency of the game fault management, we provided a method of games software fault management on MSC and achieved the editing and storage techniques about MSC; based on TTCN-3 test techniques, we used model-driven approach to activate MSC. The experimental results show that the method of fault management can reduce the workload, and improve the efficiency of the test.
We address the problem of rapid development of complex real-time task-sets through a Model Driven Development (MDD) approach. The task-set is specified according to the graphic formalism of timeline schemas and it is translated into C-code that implements the dynamic architecture of the task-set on top of Linux-RTAI operating system. The transformation is performed through an engine obtained as an...
Testing to ensure service QoS is a key problem for Web service adoption. One of the key problems for software testing is designing the finite test suit tailored to test case generation efficiently. This paper focuses on abstract test suite and executable test suite analysis of WSDL_based Web service and proposes automated WSDL_based Web service testing. A XML_based test scripting language is discussed...
In every application domain, achieving interoperability among heterogenous information systems is a crucial challenge and alliances are formed to standardize data-exchange formats. In the healthcare sector, HL7-V3 provides the current international reference models for clinical and administrative documents. Codices, an Italian company, provides the PICASSO platform that uses HL7-V3 as the pivot format...
In this paper, we perform experiments on interoperability testing of presence service on IMS platform. Open source implementations such as an IMS platform, a presence server, an XCAP server, and IMS clients are deployed to establish testbed for interoperability testing of presence service. Test cases for SIMPLE presence protocol developed by OMA are applied to our testbed and test results are analyzed...
Cost-effectiveness is perhaps the most driving characteristic behind a test automation approach aiming to spend less time in testing a software and finding as many faults as possible. Many research papers have been addressing the automation of test case generation activity by means of models, methods, tools and frameworks. However, in a practical software development environment it is not reasonable...
