Two-chamber Tester for Cordless Drills
Kabátník, Václav ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
This thesis deals with the design and subsequent realization of a bicameral tester for cordless drills. The tester will contain with two chambers in which the device will be tested. Part of the solution is the description of the parameters of the tested devices and the design of the tester concept. In addition, the thesis deals with the design of a mechanical structure that will test the equipment in both chambers and then design and realization of the relevant electrical equipment including the electrical switchboard. The thesis describes the Mosaic development environment for development of the PLC program according to IEC 61131-3. In this environment, control software has been created, which is described in its chapter. At the end of this work are enclosed images confirming the implementation to the real system and its functionality

Influence of Dynamic Bandwidth Allocation over Optical Network Unit
Sikora, Pavel ; Oujezský, Václav (referee) ; Horváth, Tomáš (advisor)
This thesis deals with DBA algorithms used in XG-PON networks. It describes reference appearance of the DBA algorithm, as well as, three specific DBA algorithms discussed in professional articles. Particularly speaking about GIANT, HYRA and modified Max-Min Fair DBA. The thesis provides description of frames utilized by DBA algorithms in XG-PON networks, specifically XGEM frame and XGTC frames. The thesis also presents a simulation tester of DBA algorithms tested on a virtual XG-PON network. Finally, it contains the results of testing these DBA algorithms with a description.

Methods of testing printed circuit boards
Průša, Tomáš ; Urbanec, Tomáš (referee) ; Raida, Zbyněk (advisor)
ABSTRACT This work describes design of tester for motherboards that uses the PC's called CM-iTC and analysis of input / output pins. There are combinations of inputs / outputs for tested boards and modules focusing on possible errors and their specifications. They include proposals for solutions to detect these errors.

Functional testing of software applications
Heinová, Tereza ; Souček, Jiří (advisor) ; Pokorný, Jan (referee)
Bachelor thesis describes the course of functional software testing. The first part defines the place and importance of testing in software development process. Explains the basic types of tests used and their purpose. Attention is paid to the roles that are in the process of testing a key role. In the second part of the work, a more detailed description of all phases of the life cycle of functional testing software. The cornerstone of the testing cycle of planning, explained there is access to the drafting process and its testing schedule. The second phase is to prepare an environment for testing. Following the completion of testing followed by evaluation of test results. Here are discussed the principles of entering errors and their subsequent solutions. Part of the preparation for testing is the selection of appropriate support tools and the creation of test scripts. Conclusion The thesis evaluates the importance of testing in software development process.

Testing during development of the banking system
Macháčková, Blanka ; Pavlíček, Josef (advisor) ; Petr, Petr (referee)
The thesis deals with software testing in company, whose activities are financial services . Emphasis is placed on the current development model , which was recently changed from waterfall type to the agile type . This transition is described using the comparison . The work is focused on the ideal composition of the scrum team. Such a team could more easily develop new functionality. Finally, described the tools that are necessary for development and testing .
The aim is to analyze and propose improvements in process development testing of new functionality to the financial system. As a result of this activity is a proposal to improve the process , not only testing, but also a process that is itself before starting the tests.
Output work is the connection of these analyzes and design process testing, which would save the company costs .
