A Tool for Generating Test Paths Based on a Given Criterion
Bíl, Jan ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
The automatic generation of test inputs according to a specified coverage criterion has the potential to significantly reduce costs in the development of critical applications. This work focuses on designing and implementing a tool that systematically generates paths in the control flow graph generated from function of such application, that meet the specified coverage criterion targets. These paths are then transformed into the corresponding SMT (Satisfiability Modulo Theories) format, and their feasibility is verified using the Z3 SMT solver. For paths that are feasible, a set of input valuations for which the formula holds is simultaneously generated. This collection of valuations formes a set of test inputs that effectively meet the desired coverage criterion. Final test inputs are tested function parameters and state of global parameters.

Extraction of Control Flow Graph from LLVM IR Format
Kondula, Václav ; Šoková, Veronika (referee) ; Smrčka, Aleš (advisor)
This Bachelor's thesis deals with design and implementation of control flow graphs extraction from source files in C and C++ language to LLVM IR format. The extractor was implemented as a standalone tool using the LibTooling interface of the Clang compiler. Output of this tool follows the requirements of platform Testos, so it can be used for automated generation of test requirements based on specified coverage criteria.

Generating of Testing Models from Source Code
Kraut, Daniel ; Malík, Viktor (referee) ; Smrčka, Aleš (advisor)
The aim of the masters thesis is to design and implement a tool for automatic generation of paths in source code. Firstly was acquired a study of model based testing and possible design for the desired automatic generator based on coverage criteria defined on CFG model. The main point of the master theis is the tool design and description of its implementation. The tool supports many coverage criteria, which allows the user of such tool to focus on specific artefact of the system under test. Moreover, this tool is tuned to allow aditional requirements on the size of generated test suite, reflecting real world practical usage. The generator was implemented in C++ language and web interface for it in Python language, which at the same time is used to integrated the tool into Testos platform.
