# tox 1.4: the virtualenv-based test run automatizer

I am happy to announce tox 1.4 which brings:

- improvements with configuration file syntax, now allowing re-using selected settings across config file sections. see http://testrun.org/tox/latest/config.html#substition-for-values-from-other-sections
- terminal reporting was simplified and streamlined. Now with verbosity==0 (the default), less information will be shown and you can use one or multiple “-v” options to increase verbosity.
- internal re-organisation so that the separately released “detox” tool can reuse tox code to implement a fully distributed tox run.

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, Holger Krekel

## 1.4

- fix issue26 - no warnings on absolute or relative specified paths for commands
- fix issue33 - commentchars are ignored in key-value settings allowing for specifying commands like: python -c “import sys ; print sys” which would formerly raise irritating errors because the ”;” was considered a comment
- tweak and improve reporting
- refactor reporting and virtualenv manipulation to be more accessible from 3rd party tools
- support value substitution from other sections with the {[section]key} syntax
- fix issue29 - correctly point to pytest explanation for importing modules fully qualified
- fix issue32 - use –system-site-packages and don’t pass –no-site-packages
- add python3.3 to the default env list, so early adopters can test
- drop python2.4 support (you can still have your tests run on python-2.4, just tox itself requires 2.5 or higher.
