Automation of regression testing
Čecháková, Lucie ; Buchalcevová, Alena (advisor) ; Doležel, Michal (referee)
This study is primarily focused on software testing, especially on regression tests and their automation. The main objective is to introduce and verify a novel procedure for implementation and automation of software regression testing. Specific objectives include putting regression testing into the context of other types of tests applied to software testing, introduction of a novel Methodology for analysis of automation of regression tests, introduction of a novel Methodology for analysis of implementation of regression tests, practical verification of the applicability of both methodologies on a real project and a suggestion of how to adapt these methodologies on the basis of practical usage. The theoretical part of this study summarizes the basic theory of software testing, decomposing it in detail, and introducing its various levels, types and categories. It also presents the field of test automation, explains its advantages and disadvantages and introduces an overview of test types, which are generally recommended for automation. More attention is paid to regression testing and its prerequisites and potential for automation. The practical part of this study consists of the proposition of two methodologies, explaining their usage in a particular practical project and focuses on the evaluation of success of practical utilization of both methodologies. Based on this evaluation, these methodologies are consequently extended. Outputs of the study are also extended variants of Methodology for analysis of automation of regression tests and Methodology for analysis of implementation of regression tests, which are available for usage on other practical projects.

Software testing effort estimation techniques
Čecháková, Lucie ; Doležel, Michal (advisor) ; Buchalcevová, Alena (referee)
This study is primary focused on software project effort estimation, especially for testing phase effort. The main objective is to verify the applicability of the method of function points for testing phase effort estimation. In my work I verify, if number of test cases, derived by experts from project function points score, relates to reality. Specific objectives include the identification of potential weaknesses in function point analysis, verification procedure for converting the number of lines of code to function points and determining the number of remaining defects generated by COQUALMO method. Theoretical part summarizes the generally applicable rules and describes in detail the four effort estimation techniques which can be used to estimate effort for application testing. After that, some of the cognitive biases of human thought processes influencing the estimates results are described. The practical part consists of an analysis of real project, focusing on estimation of amount of the test cases using function points analysis.
