pytest-mypy 0.3.3

Mypy static type checker plugin for Pytest

Mypy static type checker plugin for Pytest

---

Features

• Runs the mypy static type checker on your source files as part of your Pytest test runs.

• Does for mypy what the pytest-flake8 plugin does for flake8.

• This is a work in progress – pull requests appreciated.

Installation

You can install “pytest-mypy” via pip from PyPI:

$ pip install pytest-mypy

Usage

You can enable pytest-mypy with the --mypy flag:

$ py.test --mypy test_*.py

Mypy supports reading configuration settings from a mypy.ini file. This is currently the only way to configure mypy through pytest-mypy. In the future pytest-mypy may offer a passthrough for command line options.

You can restrict your test run to only perform mypy checks and not any other tests by using the -m option:

py.test --mypy -m mypy test_*.py

Contributing

Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.
