Question

我在使用tox时遇到了一些麻烦。测试无法运行，因为找不到测试模块。从我所做的挖掘中，我怀疑问题可能是tox正在使用错误的解释器运行测试。我正在使用Windows，如果那是相关的。

无法找到包，即使它已安装进入venv：

这是目录结构，我已将项目导入PyCharm并解析了模块而没有抱怨：

src/
src/redditbotbuilder/
src/redditbotbuilder/bots.py
src/redditbotbuilder/__init__.py
tst/
tst/redditbotbuilder/
tst/redditbotbuilder/test_bots.py
tst/redditbotbuilder/__init__.py
tox.ini
setup.py

这是setup.py：

setup(
    name="RedditBotBuilder",
    description="A Python framework for quickly building reddit bots",
    version="1.0.0",
    url="someUrl.com",
    author="Guy McGuyerson",
    author_email="guymcguyerson@gmail.com",
    classifiers=[
        "Programming Language :: Python",
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
        "Intended Audience :: Developers",
        "Topic :: Software Development :: Libraries :: Python Modules"
    ],
    packages=find_packages("src"),
    package_dir={'': 'src'},
    install_requires=["praw"]
)

这是tox.ini：

[tox]
envlist = py36

[testenv]
deps=pytest
commands=pytest --verbose tst/

RedditBotBuilder已安装在venv：

中

(py36) C:\Users\galli\Desktop\projects\RedditBotBuilder\.tox\py36\Scripts>pip list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.

我认为可能使用了错误的翻译......

(py36) C:\Users\galli\Desktop\projects\RedditBotBuilder\.tox\py36\Scripts>where python
C:\Users\galli\Desktop\projects\RedditBotBuilder\.tox\py36\Scripts\python.exe
C:\Users\galli\AppData\Local\Programs\Python\Python36-32\python.exe

...但是在将语句import sys; print(sys.executable)添加到测试文件后，它打印了C:\Users\galli\Desktop\projects\RedditBotBuilder\.tox\py36\Scripts\python.exe。

是的，我终于发现了这个问题。测试模块似乎遮蔽了被测模块的名称。如果我将测试模块名称更改为“notredditbotbuilder”，一切正常。我不确定为什么PyCharm没有强调这个问题，但我不想再浪费时间了。

测试因tox而失败，因为无法找到被测模块
