tox-pipenv

A tox plugin to replace the default use of virtualenv with Pipenv.

This is a convenient way to retain your use of Pipenv, whilst testing multiple versions of Python.

Installation

pip install tox-pipenv

Or,

pipenv install tox-pipenv

Creating virtual environments

With this plugin, tox will use pipenv --python {python binary} as given to the tox interpreter for each python path.

If you already have virtual environments cached with tox, use the --recreate flag to recreate them with pipenv.

Note: tox will pass the --site-packages flag to pipenv if this is configured in your tox config.

The Pipfile will exist in .tox/{env}/Pipfile as well as Pipfile.lock

Installing requirements

The installation of requirements from your tox config will be passed to pipenv install for installation into the virtual environment. This replaces the use of pip within tox.

requirements.txt files will also be parsed by Pipenv and used for each test environment

Executing tests

Each of the commands in your testenv configuration will be passed to pipenv to execute within the pipenv virtual environment

Example tox.ini

This simple example will test against Python 2.7 and 3.6 using pytest to execute the tests.

[tox]
envlist = py27, py36

[testenv]
deps =
    pytest
    pytest-mock
commands = python -m pytest test/

Frequently asked questions

Where to install

Tox-Pipenv should be installed in the same environment as Tox, whether that is in a virtualenvironment, system environment or user environment. Tox-Pipenv depends on Tox 3.0 or newer.

Is user expected to create Pipfile and Pipfile.lock before executing tox with this plugin?

Yes, although if you are migrating from a requirements.txt to a Pipfile, you can use Pipenv to create the Pipfile for you.

Is Pipfile.lock expected to be under source control?

According to pipenv documentation, Pipfile.lock is not recommended under source control if it is going to be used under multiple Python versions.

What is the role of requirements.txt file?

Often, tox users use requirements.txt which is then referenced from within tox.ini file as deps. Pipenv will automatically install any packages listed in requirements.txt for each virtual environment that Tox creates.

Is tox.ini deps section really in control?

No, this is a known limitation.
