Print environment variables, package version and generic attributes, as they are at the beginning of the test.
Useful in the continuous integration to dump test
configuration/environment and or to check if attributes are properly set
(ie. you change environment with os.environ)
install via::
pip install pytest-echo
$ pytest --echo-env=HOME

Package version:
pytest_echo: 0.1
plugins: echo, pydev, cov, cache, django
Note
The first attempt to retrieve the version is done via setuptools
if it fails, the module is imported (__import__(package)) to retrieve the version reading
get_version, __version__, VERSION, version so any module
level code is executed. This should be not an issue as no problematic code
should be present in the first level of the package
$ pytest --echo-attr=django.conf.settings.DEBUG

Note
Be careful when use --echo-attr. It loads any module in the path and this will execute any module level code
If you try to dump a property, related getter will be executed.
[!NOTE] You cannot dump callable result.
Example of use in a django project:
[pytest]
addopts = -vvv
--tb=short
--capture=no
--echo-env PWD
--echo-env VIRTUAL_ENV
--echo-env DBENGINE
--echo-version django
--echo-version pip
--echo-version pytest-echo
--echo-attr django.conf.settings.DATABASES.default.ENGINE

Starting from version 1.5, is possible to glob packages version and environment variables, as:
$ pytest --echo-version=pytest-* --echo-env=VIRTUAL*
or
[pytest]
addopts = -vvv
--echo-env VIRTUAL*
--echo-version pytest-*
