Nowadays the development speed of new software products is a key to success and it is not important whether the aim is to make customer's urges satisfied or get ahead of one's competitors and fill the market gap. Because of the increase of development speed the demands on the saving process of software quality are increasing. There are two types of tools that are supporting the process of software quality assurance. Firstly, we talk about comprehensive testing tools of commercial character that usually include many functions, but their purchase is extremely expensive. On the other hand there are open-source tools that are available for free, they function on many kinds of operating systems and it is possible to modify them. Unfortunately their functions are basically focused on a certain subset of controlling the software quality assurance. Company TRASK solution a.s. has decided to change this current situation, so it asked competence centre Software Quality Assurance at the University of Economics in Prague in order to create Integrated Testing Node (ITN) that would combine the advantages of open-source tools. Moreover, it would offer broad range of functions as commercial solution. The purpose of this thesis is to describe relevant phases of the process of creating the Integrated Testing Node from the factual and methodical point of view. This aim is divided into partial aims included task analysis and the proposal of solving system, open-source products portfolio analysis, choice of the most convenient tools for following integration, choosing the method of information system building, evaluating the feedback from a client and the proposal of future development of this tool. As far as the biggest contribution of this thesis is concerned, it is the realisation of ITN project that can be used during information classes at the University of Economics in Prague. Furthermore, it can be used as the control of software quality in commercial companies.

The title of graduation work is development of techniques of software testing. The objective of research is studying of the testing process, defect types in the software and their tracking, methods of creating and applying test cases, and development of auto-test project for the web service “Expert”. An additional objective is to conduct stress testing for the web service "Expert". The first part is devoted to the theoretical foundations of testing: a place of testing in software development, testing process in it-companies, review of defects and their tracking, and techniques of creating tests and their applying. The second part is devoted to the review of software for load testing and it’s practical usage for testing the web service “Expert”. The last part is devoted to the study of automation functional testing and development of the auto test project for the web service “Expert”. The graduation work consists of an introduction, 12 chapters and conclusion on 106 pages, including 55 figures and the list of 15 references. / Тема выпускной квалификационное работы: разработка методики тестирования программного обеспечения. Цель работы: изучение процесса тестирования, видов дефектов в ПО и их отслеживание, способов создания и применения тест кейсов, и, на основе полученных знаний, разработка проекта авто-тестов для веб-сервиса "Эксперт". Дополнительной целью является проведение нагрузочного тестирования для веб-сервиса "Эксперт". Первая часть работы посвящена теоретическим основам тестирования: место тестирования в разработке ПО, процесс тестирования в IT-компаниях, обзор дефектов, способов их отслеживания, а также техник создания тестов и их применение. Вторая часть посвящена обзору ПО для нагрузочного тестирования и его практическое использование для тестирования веб-сервиса «Эксперт». Третья часть посвящена изучению процесса автоматизации функционального тестирования и разработке авто-тестов для веб-сервиса «Эксперт». Выпускная работа состоит из введения, 12 глав и заключения, изложенных на 106 страницах, а также списка литературы и приложений. В работе имеется 55 рисунков. Список литературы содержит 15 наименований.

The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.
