Volba nástroje pro funkční automatizované testování webových aplikací

This diploma thesis is focused on software quality, specifically on tools for functional automated testing of web applications. The main goal is to identify and describe tools for automated functional testing of web applications and to recommend the most suitable tool for a model business environment. The theoretical part describes the basic concepts and levels of software testing, issues of test environments and data. Furthermore, the theoretical part is focused on the field of automated testing. Its advantages and disadvantages and the necessary prerequisites for successful implementation are presented. The architecture of automated testing and the resulting approaches in the relationship between the software development process and its testing are described in more detail. The ways in which test scripts can be created are mentioned, as well as the economic side in terms of return of investment in test automation. The practical part of the work contains a description of the model organization, a selected part of its testing strategy and a description of how the work on the project is organized. The next part is focused on selecting a suitable tool for functional automated testing of web applications. The requirements of the organization and criteria for the evaluation of tools are defined, a market analysis is performed, and selected tools are evaluated. To connect the diploma thesis with the practical part, a reference test scenario was defined, which was automated, and its execution took place. The results of the experiment were further used for the evaluation of tools by the method of multicriteria analysis and subsequently the most suitable tool for use in a model organization was recommended.
