[英]How to set the environment variable in tox?
我有 tox 2.9.1
$ tox --version
2.9.1 imported from /Library/Python/2.7/site-packages/tox/__init__.pyc
registered plugins:
tox-pyenv-1.1.0 at /Library/Python/2.7/site-packages/tox_pyenv.pyc
文件結構及內容如下
$ tree .
.
├── setup.py
├── test_env.py
└── tox.ini
0 directories, 3 files
安裝程序.py
$ cat setup.py
from setuptools import setup
setup(name="Tox Testing")
配置文件
$ cat tox.ini
[tox]
envlist = py35
setenv =
XYZ = 123
[testenv]
deps=pytest
commands=py.test
測試環境.py
$ cat test_env.py
import os
def test_env():
assert os.getenv('XYZ') == 123
當我運行tox
命令時,我的測試失敗了。
$ tox -v

從setenv
的文檔看來它應該設置環境變量。
setenv
必須在[testenv]
:
[tox]
envlist = py35
[testenv]
deps=pytest
commands=py.test
setenv =
XYZ = 123
根據文檔,您可以讓測試環境從[base]
繼承值。
[tox]
envlist =
test1
test2
[base]
setenv =
XYZ = 123
[testenv:test1]
deps=pytest
commands=py.test
setenv =
{[base]setenv}
[testenv:test2]
deps=pytest
commands=py.test
setenv =
{[base]setenv}
您可以使用以下方法將所有 einvornment 變量傳遞給測試:
[testenv]
passenv = XYZ
