tox.ini

# Tox (http://tox.testrun.org/) is a tool for running tests
# in multiple virtualenvs. This configuration file will run the
# test suite on all supported python versions. To use it, "pip install tox"
# and then run "tox" from this directory.

# NOTE: if you use conda for environments and  an error like this:
# "ERROR: InterpreterNotFound: python3.8"
# then run `pip install tox-conda` to use conda to build environments

[tox]
# this is the list of tox "environments" that will run *by default*
# when you just run "tox" alone on the command line
# non-platform appropriate tests will be skipped
# to run a specific test, use the "tox -e" option, for instance:
# "tox -e py38-macos-pyqt" will test python3.8 with pyqt on macos
# (even if a combination of factors is not in the default envlist
# you can run it manually... like py39-linux-pyside2)
