Regression Tests

Features of using the regression test selection method for automated testing of the graphical user interface in the development of information systems that consist of a set of modules are considered. The source of the need to create additional test environments required in the development of multi-module information systems that are using databases is specified. The three most popular approaches to organizing test environments – Copying, Scaling, and Scaling with synthetic data generation – are considered. The positive and negative sides are considered in terms of implementation, using, and resources spent on creating and maintaining resources, as well as in terms of the reliability of the results obtained in the process of testing models created using these approaches. The positive aspects of checking the quality of complex multi-module information systems from the point of view of the graphical user interface by various testing methods and, in particular, in the process of performing regression testing are presented. The positive aspects of using regression testing automation in conditions of lack of resources using various software platforms are indicated. The advantages of using the dynamic selection method for regression tests for automated testing are also given, as well as recommendations for implementing the selection method in existing and beginning projects.

Dipolar Model

Automatic estimation of current dipoles from biomagnetic data is still a problematic task. This is due not only to the ill-posedness of the inverse problem but also to two intrinsic difficulties introduced by the dipolar model: the unknown number of sources and the nonlinear relationship between the source locations and the data. Recently, we have developed a new Bayesian approach, particle filtering, based on dynamical tracking of the dipole constellation. Contrary to many dipole-based methods, particle filtering does not assume stationarity of the source configuration: the number of dipoles and their positions are estimated and updated dynamically during the course of the MEG sequence. We have now developed a Matlab-based graphical user interface, which allows nonexpert users to do automatic dipole estimation from MEG data with particle filtering. In the present paper, we describe the main features of the software and show the analysis of both a synthetic data set and an experimental dataset.

This article is dedicated to the development of a software model with a Graphical User Interface (GUI) to simulate the process of ensuring information and cyber security of information systems (IS) of Critical Infrastructure objects (CI) based on the analytical model developed by the author of this article. The specified software model with a GUI makes it possible, using the controls located on the main panel, to set the input parameters of the simulated object and observe its output characteristics using appropriate visualization elements such as special windows for displaying calculated numerical values of the main characteristics of the systems under study.

The article considers the forming a pool of regression tests when using the CI/CD process in the development of information systems consisting of a significant number of interacting modules and using various database management systems. The reasons that do not allow using standard filters of testing management systems to account for possible interactions between modules of the developed information system are indicated. The method of selection of the tests to consider the interaction and potential mutual influence of modules on each other, which also minimizes the pool of selected tests, and rank tests for significance from the point of view of a decision on the correctness of the implementation of the functionality of the information system and the system's readiness for its transfer to the customer. The method of dynamic selection of tests that allow to quickly evaluate changes made to the components of the information system in terms of possible negative impact on the unaffected components and functionality is considered. The advantages and disadvantages of the considered methodology, the necessary conditions for its successful application, and ways to implement it both in new projects for the development of information systems and in existing projects in continuous development and without the possibility of organizing code freezing are given.

AbstractRapid development of community health information networks raises the issue of semantic interoperability between distributed and heterogeneous systems. Indeed, operational health information systems originate from heterogeneous teams of independent developers and have to cooperate in order to exchange data and services. A good cooperation is based on a good understanding of the messages exchanged between the systems. The main issue of semantic interoperability is to ensure that the exchange is not only possible but also meaningful. The main objective of this paper is to analyze semantic interoperability from a software engineering point of view. It describes the principles for the design of a semantic mediator (SM) in the framework of a distributed object manager (DOM). The mediator is itself a component that should allow the exchange of messages independently of languages and platforms. The functional architecture of such a SM is detailed. These principles have been partly applied in the context of the HEllOS object-oriented software engineering environment. The resulting service components are presented with their current state of achievement.
