Most automated testing techniques for graphical user interfaces (GUIs) produce test cases that are only concerned with covering the elements (widgets, menus, etc.) on the interface, or the underlying program code, with little consideration of test case semantics. This is effective for functional testing where the aim is to find as many faults as possible. However, when one wants to mimic a real user...
Graphic user interface (GUI) is an integral part of many software applications. However, GUI testing remains a challenging task. The main problem is to generate a set of high-quality test cases, i.e., sequences of user events to cover the often large input space. Since manually crafting event sequences is labor-intensive and automated testing tools often have poor performance, we propose a new GUI...
The number of diabetes patients is increasing dramatically. Diabetes has many reasons and can lead to severe complications. It has been proven that early diagnosis and effective monitoring and assistance can decrease the effect of this disease. Thus, this paper presents general diabetes system for patient's pre-diagnosis, monitoring and assistance. Client java graphical interfaces, in addition to...
Developers often try to find occurrences of a certain term in a software system. Traditionally, a text search is limited to static source code files. In this paper, we introduce a simple approach, RuntimeSearch, where the given term is searched in the values of all string expressions in a running program. When a match is found, the program is paused and its runtime properties can be explored with...
Existing software analysis methods for performanceand coverage are typically tied to the source code of software applications.In this work, we extend these methods to the Graphical User Interfaces (GUI) of applications, motivated by the desire to bring the user perspective into focus of software quality assurance and testing at the GUI level. We present and discuss various profiling procedures, their...
The Travelling Salesman Problem is defined as returning to the starting point after visiting all the points with the least cost. In this study, a real-world application that calculates the route of the Travelling Salesman Problem using the current traffic intensity information from Google Maps is prepared. Different methods such as Exhaustive Search, Heuristic A-Star Search, BitMask Dynamic Programming,...
Refactoring engines are standard tools in today's Integrated Development Environments (IDEs). They allow programmers to perform one refactoring at a time, but programmers need more. Most design patterns in the Gang-of-Four text can be written as a refactoring script - a programmatic sequence of refactorings. In this paper, we present R3, a new Java refactoring engine that supports refactoring scripts...
Written development discussions occurring over different communication means (e.g. issue trackers, development mailing lists, or IRC chats) represent a precious source of information for developers, as well as for researchers interested to build recommender systems. Such discussions contain text having different purposes, e.g. discussing feature requests, bugs to fix etc. In this context, the manual...
In a development process where testing is highly automated, there is a major challenge to cope with issues such as huge test size and test stability. In this paper, we propose a model-based testing (MBT) tool called JCUnit, which generates a test suite from a model given as a Java class. Unlike other tools, it is designed to generate small and stable test suites and supports various popular models...
An operational analysis of agent based voltage and outage monitoring system for power distribution network would be presented in this paper. Sri Lankan distribution network has been upgraded recently with some of the new technological features such as automatic meter reading, remote breaker operations etc. But most important activities in the distribution system such as fault identifications, voltage...
In this paper we present preliminary results of an empirical study, in which we used copy/paste detection (PMD CPD implementation) to search for repeating documentation fragments. The study was performed on 5 open source projects, including Java 8 SDK sources. The study shows that there are many occurrences of copy-pasting documentation fragments in the internal documentation, e.g., copy-pasted method...
With the advance of the cloud computing technology, online-programming services that can be available through a Web browser have been widely spread. In a programming class, a teacher can efficiently manage each students' progress by introducing such an online-programming service to the students. In this study, we design and implement a cloud-based Java learning system for effectively teaching Java...
GUIs are event-driven applications where the flow of the program is determined by user actions such as mouse clicks and key presses. GUI testing is a challenging task not only because of the combinatorial explosion in the number of event sequences, but also because of the difficulty to cover the large number of data values. We propose GUICat, the first cloud-based GUI testing framework that simultaneously...
Today, some Java program learning support systems have been proposed. Each student has his/her own learning level. It is important to give questions suitable for his/her learning level for each student. But it will cause an enormous burden to the teacher. In this paper, we implement the automatic generating function and the scoring function regarding debugging questions in Java programming learning...
Reconstructing new software system from legacy one is a complex and essential process. To benefit from the new technologies quality and advantages we proposed a model-based approach relies on developing separate models capturing various aspects such as tasks, presentation and dialog structures and behaviors. To do so, the software artefacts must be analyzed and corresponding models need to be created...
It is a fact that a lot of software is written by people without a formal education in software engineering. As an example, material scientists often capture their knowledge in the form of simulation software that contains sophisticated algorithms representing complex physical concepts. Since software engineering is typically not a core skill of these scientists, there is a risk that their software...
In-Vehicle Infotainment (IVI) applications are gaining more and more attention in the automotive industry. For application development different technologies are used, typically Linux-based, accompanied with various proprietary IDE tools. Cross-platform applications are therefore not easy to create, ramp up time to start a development project is large and require specific know-how. In this paper,...
This paper describes a new approach to develop remote Control laboratories accessible from modern web-browsers and student devices (PCs, laptops, tablets and smartphones) based on TwinCAT Programmable Controllers (PLCs), Easy JavaScript Simulations (EJsS) webpages, and a Node.js laboratory web-server. On the one hand, implementing the laboratory back-end application (responsible of closing the feedback...
In this paper, we show the successful integration of measurement of code quality into a software development process. Besides choosing a suitable tool for code analysis, metrics, and proper threshold values, concepts for removal of deficiencies are important requirements for code quality. Several cycles of a development process are necessary to achieve a long-term and effective integration of code...
The Human Activity Recognition is a context awareness application, which has, for example, sports, security and health monitoring applications. As a way to acquire the human activity data, there are external approaches (e.g. cameras data) and embedded approaches (e.g. accelerometer data). In this area, we can find solutions using multiple sensors simultaneously supporting the real time data acquisition...
