Web Application Performance Testing
Martinák, Lukáš ; Letko, Zdeněk (referee) ; Burget, Radek (advisor)
This thesis is about software testing and mainly focused on performance testing of web applications. The introductory chapters outline problems of testing, identification of key issues, explanation of general concepts and software quality, differences between desktop and web application testing and finally - performance testing. Then, there is chosen a web application suitable for testing (Kentico CMS 6) and comparison of existing tools for performance and load testing. One of them (Microsoft Visual Studio 2010 Ultimate Edition) is chosen for the further testing. Therefore, several test scenarios are designed and implemented (including demonstration of creating, editing and debugging, extending with plug-ins, maintaining, running in a distributed environment, etc.). Finally, there are introduced testing reports and suggestions for the further testing.

Advanced Automated Testing of Extensive Information Systems
Svoboda, Vladimír ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
The goal of this thesis is to research current options in automated testing of information systems, create testing tools for automatic validity check of the Webnode system. These tools were created using Java programming language in combination with Selenium library. They can be used for local or even for remote testing with BrowserStack and SauceLabs. These two services are used for running your tests under many different operating systems and browser versions. The product of this thesis will help developers of Webnode project to automatically verify the validity of new features. It will show to the reader, how to use Selenium library to automate web browser, how to use it for automated testing of information systems and also how to connect it with BrowserStack and SauceLabs services.

Client-Server Relationship in Web Applications
Kučera, Petr ; Petřík, Patrik (referee) ; Šperka, Svatopluk (advisor)
This paper conducts a research in the field of transferring application logic to clients in web applications in order to reduce server load. It examines actions that can be performed on the client side in area of generating HTML code from structured data and data manipulation operations eliminating the need to communicate with server. It describes implementation of a JavaScript framework which turns this knowledge into practical use. It shows its usability on a simple information system. The results of the measurements show that the goal has been achieved and that the framework shows the way in which web applications with a strong emphasis on reducing server load can be made.

The Tool for Penetration Tests of Web Applications
Dobeš, Michal ; Malinka, Kamil (referee) ; Barabas, Maroš (advisor)
The thesis discusses the issues of penetration testing of web applications, focusing on the Cross-Site Scripting (XSS) and SQL Injection (SQLI) vulnerabilities. The technology behind web applications is described and motivation for penetration testing is given. The thesis then presents the most common vulnerabilities according to OWASP Top 10. It lists the principles, impact and remediation recommendations for the Cross-Site Scripting and SQL Injection vulnerabilities. A penetration testing tool has been developed as a part of this thesis. The tool is extendable via modules. Modules for detection of Cross-Site Scripting and SQL Injection vulnerabilities have been developed. The tool has been compared to existing tools, including the commercial tool Burp Suite.

Framework design for automated testing of web sites
Sieber, Lukáš ; Šteffan, Pavel (referee) ; Frk, Martin (advisor)
This master's thesis is based on automated web applications testing with freeware instrument utilization developed under Google code project. It is called Selenium webdriver and become very popular during last years. Selenium webdriver is frequently used for web pages automation. Indisputable advantages of this solution are low entry cost, selenium is broadly used and also live community around that instrument with many useful informations. Main goal of this thesis is creation of automation framework created by Java programming language. This final framework will integrate Selenium webdriver and guarantee easy creation of testing scenarios. Because of this goal is placed mainly on separation of web page programmatic description and description of testing scenario.
