配置django以查找所有模块中的所有doctest?

我刚才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自己的test.py文件中,这样它们就不会与我的应用程序代码的其余部分混淆。只需在每个模块中查找文档测试,并在找到它们时运行它们,就可以很容易地修改它。

使用 django-nose 因为nose会自动递归地查找所有测试。

以下是解决方案的关键要素:

测试:

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() 遍历模块树并查找python包。

感谢亚历克斯和保罗。这就是我想到的:

# 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)

我没有跟上德加诺的测试速度,但据我所知,它使用自动 unittest 发现,就像 python -m unittest discover 鼻子。

如果是这样,只需将以下文件放在发现它的地方(通常只是命名问题 test_doctest.py 或类似的)。

变化 your_package 到要测试的包。所有模块(包括子包)都将接受博士学位。

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
