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,那么在这本字典中有没有比枚举它们更简单的方法?理想情况下,我只想让Django在myapp应用程序的所有模块中找到所有doctests。
是否有某种反射黑客可以让我到达我想去的地方?

我不久前为自己解决了这个问题:
apps = settings.INSTALLED_APPS for app in apps: try: a = app + '.test' __import__(a) m = sys.modules[a] except ImportError: #no test jobs for this module, continue to next one continue #run your test using the imported module m
这允许我将每个模块的测试放在他们自己的test.py文件中,这样他们就不会与我的应用程序代码混淆了。修改它只是在每个模块中查找doc测试并在找到它们时运行它们很容易。

使用django-nose,因为nose会自动以递归方式查找所有测试。

以下是解决方案的关键要素:
tests.py:
def find_modules(package):
"""Return list of imported modules from given package"""
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 ('__init__.py', 'test.py')]
return [imp.load_module(file, *imp.find_module(file, package.__path__)) for file in files]
def suite(package=None):
"""Assemble test suite for Django default test loader"""
if not package: package = myapp.tests # Default argument required for Django test runner
return unittest.TestSuite([doctest.DocTestSuite(m) for m in find_modules(package)])
要添加递归,请使用os.walk()
来遍历模块树并查找python包。

感谢Alex和Paul。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)

我不能加快Djano的测试速度,但据我所知,它使用自动unittest发现,就像python -m unittest discover
和Nose一样。
如果是这样,只需将以下文件放在发现将找到它的位置(通常只需将其命名为test_doctest.py
或类似)。
将your_package
更改为要测试的包。所有模块(包括子包)都将被证明。
import doctest
import pkgutil
import your_package as root_package
def load_tests(loader, tests, ignore):
modules = pkgutil.walk_packages(root_package.__path__, root_package.__name__ + '.')
for _, module_name, _ in modules:
try:
suite = doctest.DocTestSuite(module_name)
except ValueError:
# Presumably a "no docstrings" error. That's OK.
pass
else:
tests.addTests(suite)
return tests
