Can't make CircleCI work along Python project set through pyproject.toml

I have setup a Python Project with dependencies listed in a pyproject.toml file as explained in PyPI packaging tutorial. Here is pyproject.toml file:

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[project]
name = "easypeasy"
version = "0.0.0"

readme = "README.md"
license = { file="LICENSE" }
requires-python = ">=3.9"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]
dependencies = [
  'pytest',
  'numpy',
]

[project.urls]
"Homepage" = "https://github.com/RandomCraftr/easypeasy"
"Bug Tracker" = "https://github.com/RandomCraftr/easypeasy/issues"

Whatever configuration file I use, CircleCI desperately look for petry section in my pyproject.toml file or look for requirement.txt, which is defintely uselesss given pyproject.toml file.

What should be config.yaml configuration file for this project to enable CircleCI to work ?

Solution

After digging documentation, it appears none "orbs" (some kind of pre-defined actions you can import) provided by circleci does the trick off the shelf for pyproject.toml configured project. Hence, I had to start from a blank config.yml to make it happen. Moreover, I had to test both Win and Linux platform. Which leads me to the following.

If you want to test your Python package with circleai
If your Python package relies exclusively on pyproject.toml definition
If you selected pytest testing framework

Then, the following config.yml file will allow you to make use of circleci CI solution for your package.
