A Python test framework, written in Rust.
We'd love for you to try Karva! It's currently in alpha, and your feedback helps shape the project. Get started or join us on Discord.
Karva aims to be an efficient alternative to pytest and unittest.
While we do not yet support all of pytest's features, we aim to gradually add support for pytest alternatives as we add features.
Karva is available as karva on PyPI.
Use karva directly with uvx:
uvx karva test
uvx karva versionOr install karva with uv, or pip:
# With uv.
uv tool install karva@latest
# Add karva to your project.
uv add --dev karva
# With pip.
pip install karvaBy default, Karva will respect your .gitignore files when discovering tests in specified directories.
To run your tests, try any of the following:
# Run all tests.
karva test
# Run tests in a specific directory.
karva test tests/
# Run tests in a specific file.
karva test tests/test_example.pyContributions are welcome! See CONTRIBUTING.md for more information.
