Hi testing folks,
I have been running into a slightly confusing problem on my Cookiecutter
dev env with the latest tox version and click.
The changes regarding ENV isolation happen to break our tox suite on
Python3 envs because Python is making a guess on the preferred encoding
which happens to be 'ascii' which in turn causes a 'RuntimeError' in
click.
Please see the according PR and the gist included.
https://github.com/audreyr/cookiecutter/pull/453
Given that this is a deliberate change in tox 2.0, I was thinking
whether we should spread the word (possibly reddit, twitter?!) so other
projects affected by this change are aware and update their tox config
accordingly.
Please let me know your thoughts and I'll be happy to contribute.
Best
Raphael

tox-2.0: plugins, platform, env isolation
==========================================
tox-2.0 was released to pypi, a major new release with *mostly*
backward-compatible enhancements and fixes:
- experimental support for plugins, see
https://testrun.org/tox/dev/plugins.html
which includes also a refined internal registration mechanism for new
testenv
ini options. You can now ask tox which testenv ini parameters exist
with ``tox --help-ini``.
- ENV isolation: only pass through very few environment variables from
the
tox invocation to the test environments. This may break test runs
that
previously worked with tox-1.9 -- you need to either use the
``setenv`` or ``passenv`` ini variables to set appropriate
environment
variables.
- PLATFORM support: you can set ``platform=REGEX`` in your testenv
sections
which lets tox skip the environment if the REGEX does not match
``sys.platform``.
- tox now stops execution of test commands if the first of them fails
unless
you set ``ignore_errors=True``.
Thanks to Volodymyr Vitvitski, Daniel Hahler, Marc Abramowitz, Anthon
van
der Neuth and others for contributions.

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

-----------
- (new) introduce environment variable isolation:
tox now only passes the PATH and PIP_INDEX_URL variable from the tox
invocation environment to the test environment and on Windows
also ``SYSTEMROOT``, ``PATHEXT``, ``TEMP`` and ``TMP`` whereas
on unix additionally ``TMPDIR`` is passed. If you need to pass
through further environment variables you can use the new ``passenv``
setting,
a space-separated list of environment variable names. Each name
can make use of fnmatch-style glob patterns. All environment
variables which exist in the tox-invocation environment will be
copied
to the test environment.
- a new ``--help-ini`` option shows all possible testenv settings and
their defaults.
- (new) introduce a way to specify on which platform a testenvironment
is to
execute: the new per-venv "platform" setting allows to specify
a regular expression which is matched against sys.platform.
If platform is set and doesn't match the platform spec in the test
environment the test environment is ignored, no setup or tests are
attempted.
- (new) add per-venv "ignore_errors" setting, which defaults to False.
If ``True``, a non-zero exit code from one command will be ignored
and
further commands will be executed (which was the default behavior in
tox <
2.0). If ``False`` (the default), then a non-zero exit code from
one command
will abort execution of commands for that environment.
- show and store in json the version dependency information for each
venv
- remove the long-deprecated "distribute" option as it has no effect
these days.
- fix issue233: avoid hanging with tox-setuptools integration example.
Thanks simonb.
- fix issue120: allow substitution for the commands section. Thanks
Volodymyr Vitvitski.
- fix issue235: fix AttributeError with --installpkg. Thanks
Volodymyr Vitvitski.
- tox has now somewhat pep8 clean code, thanks to Volodymyr Vitvitski.
- fix issue240: allow to specify empty argument list without it being
rewritten to ".". Thanks Daniel Hahler.
- introduce experimental (not much documented yet) plugin system
based on pytest's externalized "pluggy" system.
See tox/hookspecs.py for the current hooks.
- introduce parser.add_testenv_attribute() to register an ini-variable
for testenv sections. Can be used from plugins through the
tox_add_option hook.
- rename internal files -- tox offers no external API except for the
experimental plugin hooks, use tox internals at your own risk.
- DEPRECATE distshare in documentation
