test-generator

Auto-generate pytest scaffolds from Python source code by parsing the AST to map code constructs to test stubs. The tool writes a test_<module>.py file in a designated output directory to bootstrap your tests quickly.

AST-based test generation uses abstract syntax tree parsing to safely analyze Python code structure without executing it. It maps public classes, methods, and functions to standard pytest test stubs in a ready-to-run layout.

The pytest test generator does not overwrite existing test files by default. It skips overwrites to protect existing tests unless you explicitly force the overwrite flag during generation.

You can bootstrap unit tests for legacy Python modules by analyzing the source code structure. The tool generates matching pytest skeletons for public functions and classes, enabling rapid test coverage for older codebases.

The best way to create a pytest skeleton is to run the tool with the path to a Python file. It parses the code structure and outputs a ready-to-run pytest scaffold in a standard layout within your tests directory.
