python - 鼻子测试 - `all_config_files` 和 `user_config_files` 的输出

Question

我有以下目录结构：

main/
    |setup.cfg
    |foo.cfg
    |tests/
          |setup.cfg
          |foo.cfg
          |test_simple.py

并测试test_simple.py：

from nose.tools import *
from nose.config import all_config_files, user_config_files

def test_singe():
    print 'all:', all_config_files()
    print 'user:', user_config_files()
    assert_true(False)

从main/我跑nosetests tests/test_simple.py，我得到：

all: ['setup.cfg']
user: []

我认为要么all_config_files或user_config_files将返回所有配置文件。但我只得到顶部setup.cfg。

根据文档：

all_config_files()
    Return path to any existing user config files, plus any setup.cfg
    in the current working directory.

user_config_files()
    Return path to any existing user config files

我希望main/tests/*.cfg找到文件。怎么了？

根据源代码，user_config_files只会从用户的主文件夹返回配置：

config_files = [
    # Linux users will prefer this
    "~/.noserc",
    # Windows users will prefer this
    "~/nose.cfg"
    ]

...

def user_config_files():
    """Return path to any existing user config files
    """
    return filter(os.path.exists,
                  map(os.path.expanduser, config_files))

all_config_filesuser_config_files将从根目录（运行nosetests的地方）返回+ setup.cfg：

def all_config_files():
    """Return path to any existing user config files, plus any setup.cfg
    in the current working directory.
    """
    user = user_config_files()
    if os.path.exists('setup.cfg'):
        return user + ['setup.cfg']
    return user

希望有帮助。
