Matrix Testing Support

I’ve just started playing around with PDM, and it looks really, really impressive

I wanted to ask you about how thie library, or PEP 582 in general, can support a test workflow that involves testing against a matrix of Python/dependency versions.

For example-

• I have a project that claims to support a wide range of python versions and a wide version range of some key dependencies
• I would like to check that claim in CI by running the tests across multiple Python versions, and multiple versions of these key dependencies

bonus points for

• leaving the project in a clean state when testing is complete
• opportunities for parallelisation

How would I go about this using PDM?

I tend to prefer Nox as a test runner, but that’s not too important.

Thanks for the hint! Already replaced tox with nox in my small project and it works like a charm (also locally where I had issues with tox using the wrong Python version).
