[RFE] use tools.mypy from pyproject.toml

[t184256]

Configuring through mypy.ini works for me, but it'd be great if mypy invoked through pytest-mypy could pick up configuration from tools.mypy section of pyproject.toml as described in https://mypy.readthedocs.io/en/stable/config_file.html.

This should already be supported (but you need to use tool.mypy, not tools).
I will add a test to ensure this support doesn't break.

[t184256]

Oh no. Sorry for bothering, it's indeed me not being attentive enough and using tools.mypy instead of tool.mypy.

[dmtucker]

No worries! It'll be good to have that test 👍

I'm not sure if it is fully taking all the configuration from the pyproject.toml file. For example, if you have the following:

[tool.mypy]
exclude = ["tests/*"]

It still runs mypy on the files that should be skipped. mypy . correctly skips the files, but pytest --mypy does not.

@djwessel That isn't specific to config in pyproject.toml actually. See #123 (comment)

tl;dr: That option isn't terribly compatible with this plugin (which aims to let Pytest decide which files get checked).
