tox 1.8: Generative/combinatorial environments specs
=============================================================================

I am happy to announce tox 1.8 which implements parametrized environments
and should otherwise be fully backward compatible to tox-1.7.2.

See https://tox.testrun.org/latest/config.html#generating-environments-conditional-settings
for examples and the new backward compatible syntax in your tox.ini file.

Many thanks to Alexander Schepanovski for implementing and refining
it based on the specifcation draft.

More documentation about tox in general:

Installation:

    pip install -U tox

What is tox?
----------------

tox standardizes and automates tedious test activities driven from a
simple ``tox.ini`` file, including:

* creation and management of different virtualenv environments
  with different Python interpreters
* packaging and installing your package into each of them
* running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks
* testing dev packages against each other without needing to upload to PyPI

best,
