Technology is moving towards new horizons and has affected almost all areas of life. Cell phones have been replaced by smart phones and emerging technology has come up with emerging issues. Testing in the smart phone area is still not mature especially in countries like Pakistan. In this study, the gap was analyzed between software testing techniques and tools, as those of smart phones and the problems faced by Pakistani testing engineers while testing a smart phone application or desktop application. The proposed methodology used in this study is based on a survey questionnaire. After reviewing literature and abstracting information from the survey, the best techniques and tools were identified and a framework was suggested for both desktop application and smart phone applications.
The realisation of Service-Oriented Architecture (SOA) to communicate data between systems running on different platforms lack an organised framework to capture all the essential elements required for successful interoperability between web applications and their services. In this work, a SOA for Data Interoperability in Web Applications (SOADIWA) was designed to address this problem. The architecture of SOADIWA was based on five layers, namely Web Application Layer (WAL), Visualization Input Layer (VIL), Visualization Output Layer (VOL), Web Service Layer (WSL) and Quality of Service Assurance Certifier Layer (QoSACL). In WAL, the Service Provider (SP) received request from the Service Requester (SR) through the Stream Socket (SS) with a connection-oriented transmission control protocol that provided appropriate website for rendering of services. The SR provided requested data which must be accepted, processed and returned for a particular need using component object model and file transfer protocols. The VIL and VOL used Breshenham´s line drawing algorithm and context-sensitive visualization techniques for data exploration and analysis.
The book focuses on both theory and applications in the broad areas of communication technology, computer science and information security. This two volume book contains the Proceedings of 4th International Conference on Advanced Computing, Networking and Informatics. This book brings together academic scientists, professors, research scholars and students to share and disseminate information on knowledge and scientific research works related to computing, networking, and informatics to discuss the practical challenges encountered and the solutions adopted. The book also promotes translation of basic research into applied investigation and convert applied investigation into practice.

Develop modular applications using the Java Platform Module System, the single most anticipated feature in Java 9. You will improve maintainability and performance of your Java applications by deploying only modules that are needed and encapsulating their implementation details. Until now Java has been monolithic. Using any one part of Java has meant incorporating the entirety of the runtime environment, an approach ill-suited to the increasing number of IoT devices such as fitness monitors, kitchen appliances, toys and games, and so forth. This book shows a new way, to make Java scale from the smallest of footprints in the smallest of devices through desktop PCs and on up to server platforms. With Java 9 Modularity Revealed you will learn to make your projects more reliable and scalable than ever using the most important feature in Java 9-The Java Platform Module System, known more commonly as Project Jigs aw. You will learn how to avoid one of the major pain points of Java programming, that of conflicting class names from different modules, or packages. You will learn to create custom run-time images that represent a minimal and more compact JRE containing only those modules that you need. You will further learn to migrate existing Java applications to modular ones using different approaches and tools. The end result is a new ability to plug together different modules without fear of namespace and other conflicts, and you can deploy to everything from small devices to large servers. This book provides code examples and explanations. What You´ll Learn Build Java applications using the new modular system introduced in Java 9 Create your own JRE consisting only of the modules that you require Adapt your testing techniques toward modular applications lare your dependencies on other modules Enable modules to export only specific packages Migrate existing Java applications to modular ones Improve maintainability and performance of Java applications Who This Book Is For Experienced Java programmers wanting to keep up and become informed on the new modularity support in Java 9
