Practical Aspects of Reducing Technical Debt in Software Products
Hricovová, Alžbeta ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis focuses on practical aspects of reducing technical debt in software products, focusing on testing, refactoring, and continuous integration. Technical debt arises from compromises made during software development and, if unaddressed, can negatively impact the product and the company developing it. One of the solutions to reduce technical debt is continuous refactoring and code maintenance. This work describes identified violations of good object-oriented programming principles in the selected product and procedures applied to the product to mitigate the impact of its technical debt.

Comparator of Test Results
Čerbák, Patrik ; Kozák, David (referee) ; Smrčka, Aleš (advisor)
Tato bakalářská práce se zaobírá tématem testování OpenJDK ve firmě Red Hat a jak toto testování zefektivnit. Jeden z hlavních problémů při testování je porovnání, zda určitý test spadl pouze na jedné variantě testovací sady nebo na více variantách (jedna testovací sada se stejnými testy má mnoho variant – liší se například v operačních systémech, běhové architektuře, atd.). Kvůli tomuto je v této práci navrhnut a implementován nástroj pro porovnávání výsledků testů právě na odlišných varintách jedné testovací sady. Tento nástroj je implementován v programovacím jazyce Java a může běžet samostatně jako CLI program nebo ve speciálním webovém prostředí. Tento komparátor je zároveň součástí takzvaného Jtreg pluginu, což je open source rozšíření do nástroje Jenkins, které se používá v OpenJDK QA týmu firmy Red Hat. Samotný nástroj umožňuje spoustu věcí, například filtrování testovacích sad pro porovnání, vytvoření porovnávací tabulky spadlých testů, tabulky s podobností stack trace spadlých testů nebo třeba tabulky porovnávající výsledek sestavení jednotlivých testovacích sad.

Automatic Testing of the BeeeOn System
Wolfert, Richard ; Hujňák, Ondřej (referee) ; Viktorin, Jan (advisor)
This Master's thesis is about analysis of Internet of Things project BeeeOn, design and production of unit, integration and system tests and their automation by utilization of Continuous integration system Jenkins CI. The theoretical part is devoted to software testing fundamentals and Continuous integration systems. The main point of this thesis is about specification and description of BeeeOn system, its requirements for automatic testing and its implementation. In conclusion, the results of this work and expansion possibilities are discussed.

C++ Arbitrary Precision Floating Point Library
Závada, Vladislav ; Šnobl, Pavel (referee) ; Hruška, Tomáš (advisor)
This thesis deals with the design of a floating point module, which allows to perform operations with floating point operands that have any bit width. For this purpose, the module is implemented as a template class in C ++. The module is designed to allow it to be used when designing an application-specific processor. First, the floating point number and template functions in c ++ are described. In the practical part the algorithms of the individual operations and the design of the module itself are described as template libraries.

Automatic Testing of JavaScript Restrictor Project
Bednář, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
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.

Web Interface for Task Management and Monitoring on Supercomputers
Dančák, Petr ; Jaroš, Jiří (referee) ; Jaroš, Marta (advisor)
Bachelor's thesis focuses on web development process to create interface for k-Dispatch system, with which we can monitor, create and edit existing tasks, users, machines, allocations and groups. Web design was created based on web content layout principle and object grouping based on similarities principle. Comparison of usable tools is in design procedure section. Implementation uses mainly written in Python3 language with usage of Flask framework, which is helpful with processing requests and user authentication. Furthermore in implementation are used languages as HTML, JavaScript, Jinja2 and other. For test phase were used unit tests together with Selenium interface and user testing.
