pytest-doctest-mkdocstrings 0.1.1

Run pytest --doctest-modules with markdown docstrings in code blocks (```)

pytest-doctest-mkdocstrings

A pytest plugin that allows you to use doctest and enclose your example code blocks in ``` codeblocks (e.g. when building documentation with mkdocs and mkdocstring).

v0.1.0 - Breaking change - you now need to specifically add the command line option --doctest-mdcodeblocks when calling pytest

Usually this docstring would fail doctest:

    """
    A function description

    Examples:
    --------
    ```
    >>> x = 1
    >>> x
    1
    ```
    """

As doctest looks for the output

Expected:
    1
    ```
Got:
    1

This plugin works by mockeypatching doctests parser when pytest begins each test session and including ``` as an identifier of the end of an expected result (a want).

It only works when doctest is invoked via pytest, not when invoking doctest directly.

If you have code examples or expected results which actually contain ``` then you'll need to re-write them.

Usage

TL;DR: invoke pytest with --doctest-mdcodeblocks

1. Strongly recommended to set up a virtual environment first! (e.g.. python3 -m venv .venv, . .venv/bin/activate)
2. Install with pip install pytest-doctest-mkdocstrings
3. Run pytest: pytest --doctest-mdcodeblocks --doctest-modules --doctest-glob="*.md"

You can also add the following to your pyproject.toml so that pytest always runs doctests:

[tool.pytest.ini_options]
addopts = [
    "--doctest-modules",
    "--doctest-glob='*.md'",
    "--doctest-mdcodeblocks"
]

To temporarily override the setting use: pytest --no-doctest-mdcodeblocks
