Python软件包结构，用于运行单元测试的setup.py

Question

我不确定我的包结构是否正确，或者我是否在setup.py中使用了正确的选项，因为当我尝试运行单元测试时出现了错误。

我的目录结构如下：

/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：

#!/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，我收到以下消息：

nate@nate-desktop:~/PycharmProjects/trendfollowing$ sudo python setup.py test

    tests.append(self.loadTestsFromName(submodule))
  File "/usr/lib/python2.6/unittest.py", line 584, in loadTestsFromName
    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？我在包结构中需要遵循其他约定吗？

Answer 1

通过一些试错，我找到了这个问题的原因。测试名称应与模块名称匹配。如果有一个名为"foo_test.py"的测试，就需要有相应的模块foo.py。

我找到了一些关于组织软件包结构的指南，这些指南帮助我重新组织我的软件包结构，让我更加自信。
