在我的情况下,py.test
命令失败了,而 pytest
运行得非常好。
我使用 pytest-flask 插件:
platform linux -- Python 3.5.2, pytest-3.0.2, py-1.4.31, pluggy-0.3.1
rootdir: /home/sebastian/develop/py/flask-rest-template, inifile:
plugins: flask-0.10.0
当我调用 $ py.test
时,我会得到以下错误:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/_pytest/config.py", line 301, in _getconftestmodules
return self._path2confmods[path]
KeyError: local('/home/sebastian/develop/py/flask-rest-template')
During handling of the above exception, another exception occurred:

from flask import Flask
ImportError: No module named 'flask'
ERROR: could not load /home/sebastian/develop/py/flask-rest-template/conftest.py
这是我的实际conftest.py
文件:
import pytest
from app.app import create_app
@pytest.fixture
def app():
app = create_app()
return app
我的项目结构如下:
.
├── app
│ ├── __init__.py
│ ├── app.py
│ └── config.py # flask configuration objects
├── conftest.py # pytest configruation
├── requirements.txt
├── ...
└── tests
└── ...
那么这两个命令的区别是什么?为什么一个失败了,而另一个没有?
更新1
1)我不得不将相对导入 from .config import Config
或 from config import Config
更改为绝对导入,如 from app.config import Config
2)使用命令 python3 -m app.app
运行 Flask
3)现在 pytest
和 py.test
正常工作了
非常感谢你们的帮助!
更新2
这变得很奇怪了...当使用绝对导入、用-m
选项运行 Python、以及开启 Flask 的debug=True
时,werkzeug
库没有像预期一样重新加载源代码:
http://chase-seibert.github.io/blog/2015/06/12/flask-werkzeug-reloader-python-dash-m.html
https://github.com/pallets/werkzeug/issues/461
https://github.com/pallets/flask/issues/1246
这在我的 app/app.py
中对我有所帮助:
if __name__ == '__main__':
app.run(debug=True, use_reloader=False)
然后 python -m app.app
运行良好。
pytest
命令是一种新的方式,你可能还残留着旧版本的pytest
。 - wimpytest
… - swiesendpython app/app.py
,我需要from config import Config
。我该如何使两者都能正常工作(运行flask和pytest)? - swiesendpython3 -m app.app
,如https://dev59.com/2WQn5IYBdhLWcg3wP1JT中所述。因此,使用绝对导入,例如`from app.config import Config,那么
py.test`也可以正常工作。 - swiesendpython3 -u -m pytest --color=auto
,它非常好用。 - user1065000
