.. image:: https://img.shields.io/pypi/v/pytest-mypy.svg
:target: https://pypi.org/project/pytest-mypy/
:alt: See Latest Release on PyPI

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_:

.. code-block:: bash

$ pip install pytest-mypy

Usage

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

.. code-block:: bash

$ py.test --mypy test_*.py

Mypy supports reading configuration settings <http://mypy.readthedocs.io/en/latest/config_file.html>_ from a mypy.ini file.
Alternatively, the plugin can be configured in a conftest.py to invoke mypy with extra options:

.. code-block:: python

def pytest_configure(config):
    plugin = config.pluginmanager.getplugin('mypy')
    plugin.mypy_argv.append('--check-untyped-defs')

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

.. code-block:: bash

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