Question

I’m writing a testing framework using Python’s unittest. I have separate modules for separate parts of the tested application (part1 – part1.py, part2 – part2.py etc.). I want to create a helper module, which will read configuration settings for each of the modules, with the config file name being the same as the module name (part1.py – part1.conf, part2.py – part2.conf). Config files will reside in the same folder as the modules do.
When I run part1.py I need to tell the tests that config for them is in part1.conf. How do I do that?
This helper module will not necessarily reside in the same folder as the test modules.
I do not want to use nose because I want to have as little external dependencies as possible.

def module_config(mod):
    '''Loads the config residing next to the module.'''
    import configparser, os.path
    cp = configparser.ConfigParser()
    cp.read_file(open(os.path.splitext(mod.__file__)[0] + '.conf'))
    return cp

# load config for some module
import some_module
module_config(some_module)

# load config for current module
module_config(sys.modules(__name__))
