How to import all the environment variables in tox

问题


I'm using following in setenv to import the environment variable from where I run, but is there a way to import all the variables so that I don't really need to import one by one.

e.g: {env:TEMPEST_CONFIG:} and {env:TEMPEST_CONFIG_DIR:} used to import these 2 variables.

[testenv:nosetests]
setenv =
    TEMPEST_CONFIG={env:TEMPEST_CONFIG:}
    TEMPEST_CONFIG_DIR={env:TEMPEST_CONFIG_DIR:}
deps = {[testenv]deps}
commands =
    find . -type f -name "*.pyc" -delete
    bash {toxinidir}/tools/setup.sh
    nosetests --with-xunit {posargs}

You can use passenv. If you pass the catch all wildcard * you have access to all environment variables from the parent environment:

passenv=SPACE-SEPARATED-GLOBNAMES

New in version 2.0.

A list of wildcard environment variable names which shall be copied from the tox invocation environment to the test environment when executing test commands. If a specified environment variable doesn’t exist in the tox invocation environment it is ignored. You can use * and ? to match multiple environment variables with one name.

minimal tox.ini to reproduce (no project necessary):

[tox]
skipsdist = True

[testenv]
passenv = *
skip_install = True
commands = python -c "print('computer says {env:MY_FANCY_ENV_VAR:}!')"

invocation in linux/unix shell:

MY_FANCY_ENV_VAR=no tox -qq

invocation on Windows cmd.exe:

set MY_FANCY_ENV_VAR=no & tox -qq

output:

computer says no!
