include group in another group

[deronnax]

Hello.
I would like to have a test group, that I would install only in CI, and include it in the general dev development group, so developers, by doing pdm sync --dev, would have both test dependencies and "normal" dev dependencies like flake8. It would theorically look like this:

[tool.pdm.dev-dependencies]
test = [
    'pytest', 
    'pytest-timeout'
]
dev = [
    '*test',
    'flake8',
    'ipython',
]

I did not find how to do it in the documentation. Can this be done? How?
Thanks

Can this be done?

Partially, only if the referred group is an optional dependency group and the project itself is a distribution, then refer it as mypackage[test]

Otherwise let's keep an eye on PEP 735

Ah, the project is not a distribution. But thank you.
