Question

我在Python包结构中存在一个问题。

以下是我在Mac OSX和Python 3.4中所做的事情：

1. mkdir MyProject
2. cd MyProject
3. virtualenv --python=python3.4 venv
4. . venv/bin/activate
5. pip install pytest pyscaffold
6. putup MyProject

然后，目录结构如下所示：

MyProject/
   MyProject/
      docs/
      myproject/
      tests/
      requirements.txt
      setup.py
      .
      .
   venv/

我在apple.py和myproject test_apple.py添加了tests。

然后，结构将是这样的：

MyProject/
   MyProject/
      docs/
      myproject/
         apple.py
      tests/
         test_apple.py
      requirements.txt
      setup.py
      .
      .
   venv/

apple.py

import sys
for path in sys.path:
    print(path)

print("start apple")

def get_apple():
    print("apple!!")
    return 5

当我在apple.py目录中输入python apple.py来运行myproject时，它会打印：

/Users/Chois/Desktop/MyProject/MyProject/myproject
/Users/Chois/Desktop/MyProject/venv/lib/python34.zip
/Users/Chois/Desktop/MyProject/venv/lib/python3.4
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/plat-darwin
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/lib-dynload
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/plat-darwin
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/site-packages
start apple

如上所示，sys.path包括/Users/Chois/Desktop/MyProject/MyProject/myproject

所以，我这样做test_apple.py：

test_apple.py

import sys
for path in sys.path:
    print(path)

from myproject.apple import get_apple

def test_apple():
    assert 5 == get_apple()

当我通过输入py.test -s test_apple.py来运行此代码时，（-s选项用于显示代码中print语句的结果）

/Users/Chois/Desktop/MyProject/MyProject/tests
/Users/Chois/Desktop/MyProject/venv/lib/python34.zip
/Users/Chois/Desktop/MyProject/venv/lib/python3.4
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/plat-darwin
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/lib-dynload
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/plat-darwin
/Users/Chois/Desktop/MyProject/venv/lib/python3.4/site-packages
Traceback (most recent call last):
  File "test_apple.py", line 5, in <module>
    from myproject.apple import get_apple
ImportError: No module named 'myproject'

然而，当我通过键入python setup.py test运行测试时，它运行时没有错误！ !!

我想知道的是如何使用py.test -s test_xxxx.py而不是python setup.py test的所有测试模块来运行特定的测试模块。

需要你的帮助，谢谢。

请阅读Good Integration Practices。

确保“mypkg”是可导入的，例如输入一次：

pip install -e . # install package using setup.py in editable mode

测试时，＆＃39; python setup.py test＆＃39;是在Python包中测试的唯一方法吗？
