Dynamic Workflow Extension for Jenkins
Sviták, Jiří ; Burget, Radek (referee) ; Letko, Zdeněk (advisor)
The main of the master's thesis has been to implement a plugin for Jenkins, which enables flow control of launching Jenkins jobs by using business processes. Project jBPM 5, which is based on Business Process Model and Notation 2.0, has been used for business processes. Two sample business processes have been drafted and successfully tested to demonstrate functionality. The main output of this thesis is the jBPM plugin for Jenkins released under free license.

Test Result Repository with Web User Interface
Vlasák, Jaroslav ; Letko, Zdeněk (referee) ; Kočí, Radek (advisor)
This thesis deals with the development of a client-server application for Red Hat company. Client participates in testing process of JBoss platform and gets user-defined performance data which sends during testing to the server application by platform independent communication. The server application allows to analyze the received data which can be also compared by several perspectives. These services for data analysis and comparison are accessible for server users using the web client. The server application supports the import of the performance data stored in the XML file and also their export for qVue portal. The client part of the application is implemented in Java and the server application is based on Java EE platform.

Portlets Based Time Management Tools
Basovník, Martin ; Kočí, Radek (referee) ; Letko, Zdeněk (advisor)
This master's thesis focuses on development of mini-applications for portal environments called portlets. Portal is an alternative type of web information systems used to dynamic portlet management, content personalization and aggregation of content from different data sources. The aim of this thesis is to try an alternative combination of technologies of portals, portlets and portlet bridges. This thesis is one of the first demonstrations of the described combination of technologies and will be used as an educational material by Red Hat company for development of portlets on their portal GateIn. The set of portlets manages user calendars, tasks and contacts. The theoretical part of this thesis compares existing tools for time management and mentions standards for data exchange in this domain. Subsequently it describes all important technologies used in this thesis. The practical part describes the design and the implementation of portlets and evaluates results of this work. The development of the described set of portlets proved that combination of technologies of portals, portlets and portlet birdges is fast and appropriate way how to develop information systems.

Design and Implement Grid Testing System
Hubík, Filip ; Letko, Zdeněk (referee) ; Kočí, Radek (advisor)
This project addresses parallelization of building and testing projects written i Java programming language. It proposes software that uses methods of continual integration, parallelization and distribution of computationally intensive tasks to grid architecture. Suggested software helps to accelerate the development of software product and automation of its parts.

Heuristic Solving of Planning Problems
Novotná, Kateřina ; Křena, Bohuslav (referee) ; Letko, Zdeněk (advisor)
This thesis deals with the implementation of the metaheuristic algorithms into the Drools Planner. The Drools Planner is an open source tool for solving optimization problems. This work describes design and implementation of Ant colony optimization metaheuristics in the Drools Planner. Evaluation of the algorithm results is done by Drools Planner benchmark with different kinds of optimization problems.

Integration of JMS Providers to Third Parties
Žiaková, Nikoleta ; Letko, Zdeněk (referee) ; Dudka, Vendula (advisor)
This thesis deals with messaging and integration of third-party JMS providers into JBoss application server. The aim of the thesis was to design and implement a general-purpose testsuite to verify the proposed integration. First requirement was to get familiar with key technologies for integration including Java Message Service, Java EE Connector Architecture, selected JMS providers and JBoss AS. Specific procedures of integration were designed and described for JMS providers Apache ActiveMQ, IBM WebSphere MQ and Red Hat MRG Messaging. The testsuite implemented to verify the functionlity of the integration focuses on four areas - transactions, clustering, high availibility and performance. The process of testing was automated using continuous integration tool Jenkins. Finally the test application was used to evaluate functionality of the integration and compare different JMS providers and various versions of JBoss AS.

Integration of Jenkins CI with Undertow
Barteček, Jakub ; Letko, Zdeněk (referee) ; Müller, Petr (advisor)
This master's thesis deals with replacement of the servlet container in Jenkins CI with server Undertow. In the thesis, general information about programs, which are related to this topic, are described and current state of the servlet container is analyzed. The result is newly created servlet container for Jenkins CI. Both versions of the Jenkins CI were performance tested and the new version gave better results.

Support for Jenkins Plugin Development in Python Language
Bambas, Tomáš ; Letko, Zdeněk (referee) ; Müller, Petr (advisor)
Jenkins CI, the continuous integration server, enables to extend its functionality by plug-ins. These plug-ins can be written in Java and Ruby. The support for Python language is missing although it is one of the most popular programming languages. Therefore we have implemented the SDK for Python plug-in development and this SDK has been integrated into the Jenkins CI community repository. The documentation for the plug-in development in Python has been also published. Thanks to that work, developers can now implement plug-ins in Python programming language.

Model-Based Testing of JBoss Drools
Široký, Petr ; Holík, Lukáš (referee) ; Letko, Zdeněk (advisor)
Model-based testing (MBT) is using a model of expected behavior of the system to automatically generate a set of tests. It aims at reducing the testing cost when compared to the traditional testing techniques. This work focuses on testing a real-world software system using the selected MBT tool OSMO. The tested system is responsible for compiling business rules and it is one of the main components of the Drools platform, developed by Red Hat. The work describes the introduction of MBT considering the good reception from the community of developers, then the creation of compiler input models and evaluation of the newly created test suite. The usage of the MBT resulted in detection of five reported and three potential issues in the tested code. Using the Drools compiler example, the work summarizes the main strengths and also weaknesses of practical use of MBT techniques.

Dynamic Data Race Detection and Self-Healing in Java Programs
Letko, Zdeněk ; Kolář, Dušan (referee) ; Vojnar, Tomáš (advisor)
Finding concurrency bugs in complex software is difficult. As a contribution to coping with this problem the thesis proposes an architecture for a fully automated dynamic detection and healing of data races and atomicity violations in Java. Two distinct algorithms for detecting of data races are presented. One of them is a novel algorithm called AtomRace which detects data races as a special case of atomicity violations. The healing is based on suppressing a recurrence of the detected problem and can be performed by introducing an additional synchronization or by legally influencing the Java scheduler. Basically forces certain parts of the code to be executed atomically. The proposed architecture uses bytecode instrumentation to be able to track and influence the execution. The architecture and algorithms were implemented and tested on multiple case studies.
