配置Django以查找所有模块中的所有doctests？

Question

如果我运行以下命令:

>python manage.py test

Django在我的应用程序中查看tests.py,并在该文件中运行任何doctests或单元测试.它还会查看__ test __字典以运行额外的测试.所以我可以链接来自其他模块的doctests:

#tests.py
from myapp.module1 import _function1, _function2

__test__ = {
    "_function1": _function1,
    "_function2": _function2
}

如果我想要包含更多doctests,那么在这本字典中是否有比简单列举更简单的方法？理想情况下,我只想让Django在myapp应用程序中查找所有模块中的所有doctests.

是否有某种反射黑客会让我到达我想去的地方？

感谢亚历克斯和保罗。这就是我想出的：

# tests.py
import sys, settings, re, os, doctest, unittest, imp

# import your base Django project
import myapp

# Django already runs these, don't include them again
ALREADY_RUN = ['tests.py', 'models.py']

def find_untested_modules(package):
    """ Gets all modules not already included in Django's test suite """
    files = [re.sub('\.py$', '', f) 
             for f in os.listdir(os.path.dirname(package.__file__))
             if f.endswith(".py") 
             and os.path.basename(f) not in ALREADY_RUN]
    return [imp.load_module(file, *imp.find_module(file, package.__path__))
             for file in files]

def modules_callables(module):
    return [m for m in dir(module) if callable(getattr(module, m))]

def has_doctest(docstring):
    return ">>>" in docstring

__test__ = {}
for module in find_untested_modules(myapp.module1):
    for method in modules_callables(module):
        docstring = str(getattr(module, method).__doc__)
        if has_doctest(docstring):

            print "Found doctest(s) " + module.__name__ + "." + method

            # import the method itself, so doctest can find it
            _temp = __import__(module.__name__, globals(), locals(), [method])
            locals()[method] = getattr(_temp, method)

            # Django looks in __test__ for doctests to run
            __test__[method] = getattr(module, method)
