The Pynguin Logo Pynguin

Pynguin (IPA: ˈpɪŋɡuiːn), the PYthoN General UnIt test geNerator, is a tool that allows developers to generate unit tests automatically.

Pynguin is developed at the Chair of Software Engineering II of the University of Passau.

About

Pynguin is a command line tool written in Python that allows to automatically generate unit tests for Python programs. It aims to remove the burden of crafting tests manually from the developer. For that Pynguin is an extensible tool that allows the implementation of various test-generation approaches; this enables the usage of Pynguin not only for developers but also for researchers.
