Combinatorial interaction testing (CIT) stands as one of the efficient testing techniques that have been used in different applications recently. The technique is useful when there is a need to take the interaction of input parameters into consideration for testing a system. The key insight the technique is that not every single parameter may contribute to the failure of the system and there could...
Interaction testing can be used to effectively detect faults that are otherwise difficult to find by other testing techniques. However, in practice, the input configurations of software systems are subjected to constraints, especially in the case of highly configurable systems. Handling constraints effectively and efficiently in combinatorial interaction testing is a challenging problem. Nevertheless,...
The SmartDriver framework is an open extension of Selenium WebDriver framework aimed at decreasing implementation and maintenance costs of automated tests. It composes from two principal modules working in synergy. The structuring module ensuring three layer architecture of reusable objects, page objects and tests. Besides decreasing of implementation and maintenance costs, this module allows to create...
Model-based testing represents an efficient method to detect software defects. This approach has a limitation, when the model of the system under test is inconsistent, incomplete, or, does not exist at all. An exploratory testing approach represents an alternative for such situations: initially it does not require a model of the tested system. The testers are using their skills and intuition to explore...
The code written by a software developer is not always flawless. The more code is created the more errors are introduced into the system. In web development different programming languages can be used to implement back-end and front-end sides of the application. For example, it is possible to implement user input validation multiple times —it validates the input values on client-side using JavaScript...
This paper deals with interactive multimedia collaboration system which was designed and developed within INDECT project. The INDECT is a 7th FP EU project and its aim is to develop solutions and tools for automatic threat detection enhancing the safety of EU citizens. The paper discusses the Interactive Audio Video System — IVAS, which is the core component of the whole INDECT project, and describes...
This paper deals with the implementation of OFDM demodulator Digital Radio Mondiale system DRM. The article is aimed to design a 64-QAM demodulator using the software tools “System Generator for DSP” from Xilinx and MATLAB-Simulink [1]. The theoretical performance has been verified by simulations. Moreover, demodulator's circuit was subsequently implemented by the programmable elements into Field-Programmable...
Reliability and correctness of a web application are crucial factors to its success. Errors occurring in non-deterministic moments do not attract the target audience of the application. It is quite impossible to deliver 100% reliable application. Hidden errors are discovered when target users are using the application. With proper tooling and support the time between the error discovery or report...
