tox-pdm 0.7.2

A plugin for tox that utilizes PDM as the package manager and installer

tox-pdm

A plugin for tox that utilizes PDM as the package manager and installer.

With this plugin, you can migrate your project to PDM while retaining the ability to test against multiple versions.

Installation

$ pip install tox-pdm

Or,

$ pdm add -d tox-pdm

Or if you installed tox via pipx, you can inject the plugin by:

$ pipx inject tox tox-pdm

Example tox.ini

The following simple example installs dev and test dependencies into the venv created by Tox and uses pytest to execute the tests, on both Python 3.7 and 3.8.

[tox]
min_version = 4.0
envlist = py37,py38

[testenv]
groups =  ; Dependency groups in pyproject.toml
    dev
    test
deps =      ; Additional dependencies, it will be installed into the library path via normal pip method
    flake8
commands =
    pytest test/

Here is another one installing the test dependencies and executing the test PDM script

[tox]
min_version = 4.0
envlist = py3{8,9,10}

[testenv]
groups = test
commands = test

If no groups are specified, the pdm install will be skipped.

A real-world example can be found at this repository's tox.ini and GitHub Action workflow.

Some best practices:

1. pdm executable must be exposed in PATH, if it is not the case, give the absolute path to tox by tox --pdm <path_to_pdm>.
2. Make sure you have generated pdm.lock before running the test, it will greatly accelerate the testing.
3. If you don't set skip_install = true, the current package will be built and installed into the testing environment together with the dependencies from pyproject.toml.
4. Reuse your PDM scripts to avoid duplication
