UTBot C/C++ generates test cases by code, trying to cover a maximum number of statements and execution paths. We treat source code as a source of truth, assuming that behavior is correct and corresponds to initial user demand. Generated tests are placed in the so-called regression suite. Thus, we fix current behavior with the help of generated test cases. Using UTBot for C/C++, developers obtain full control of their code. No future change can break the code without being noticed once it's covered with tests generated by UTBot. This way, modifications made by developers to an existing code are much safer. Hence, with the help of generated unit tests, UTBot provides dramatic code quality improvement.

For now, you can only use UTBot under Ubuntu 20.04 and above. Navigate to the Releases GitHub page and download last version of UTBot.

UTBot is distrbuted as an archive that contains:

1. A pack utbot_distr.tar.gz that contains UTBot binary and its dependencies;
2. UTBot plugin for Visual Studio code — utbot_plugin.vsix;
3. A version version.txt;
4. A run script unpack_and_run_utbot.sh.

To launch UTBot, unzip the archive and run the ./unpack_and_run_utbot.sh command (we recommend doing it in a fresh directory to make UTBot removing easier). To remove UTBot, simply delete this directory.

To install UTBot VSCode plugin, use VSCode Install from VSIX command.
