Python 包结构，setup.py 用于运行单元测试 [英] Python package structure, setup.py for running unit tests

问题描述

我不确定我是否正确地组织了我的包结构或在 setup.py 中使用了正确的选项，因为我在尝试运行单元测试时遇到错误.

I'm not sure I'm organizing my package structure correctly or am using the right options in setup.py because I'm getting errors when I try to run unit tests.

我有这样的结构:

/project
   /bin
   /src
       /pkgname          
           __init__.py
           module1.py
           module2.py
   /tests
       __init__.py
       test1.py
       test2.py

我的 setup.py 看起来像这样:

My setup.py looks like this:

#!/usr/bin/env python                                                                                                                                        
from setuptools import setup, find_packages

setup(version='0.1',
      description='Trend following library',
      author='Nate Reed',
      author_email='[e-mail]',
      packages=find_packages(),
      install_requires=['numpy'],
      test_suite="tests",                          
)

当我运行python setup.py test"时，我得到:

When I run 'python setup.py test' I get:

    parent, obj = obj, getattr(obj, part)
AttributeError: 'module' object has no attribute 'test1'

测试名称是否需要与模块名称匹配?在我的包结构中是否还有其他约定需要遵循?

Do the test names need to match module names? Are there other conventions I need to follow in my package structure?

推荐答案

通过反复试验，我找到了这个问题的原因.测试名称应与模块名称匹配.如果有foo_test.py"测试，就需要有对应的模块foo.py.

Through some trial and error, I found the cause of this problem. Test names should match module names. If there is a "foo_test.py" test, there needs to be a corresponding module foo.py.

我找到了一些关于组织包结构的指南，这帮助我将我的包重新组织成一个我有信心的结构.

I found some guidelines on organizing package structure, which helped me reorganize my package into a structure I was confident in.
