I'm testing efficiency of three mysql connector libraries: mysql-connector, MySQLdb and oursql, within sqlalchemy. Took me a while to prepare basis, but after that, I began to wonder, how to make more methods, and run them, without worrying about their inclusion into testing process?

After searching a while, I've found several solution, but the best one employed dir:

import types
import module

alchemy_tests = [module.__dict__.get(test) for test in dir(module)
                     if isinstance(module.__dict__.get(test), types.FunctionType)
                        and test.startswith('sqltest_')]

There are two parts, first one is iterating over module's elements:

module.__dict__.get(test) for test in dir(module)

Second one is condition, telling when do we want to include module's element in a list:

if isinstance(module.__dict__.get(test), types.FunctionType) and test.startswith('sqltest_')

Now remember, that list returned by dir contains only names, hence the module.__dict__.get, which returns module's elements.

And here's unfolded version:

import types
import module

alchemy_tests = []
    for test in dir(module):
        if isinstance(module.__dict__.get(test), types.FunctionType) \
            and test.startswith('sqltest_'):
            alchemy_tests.append(module.__dict__.get(test))
