Python - How to pass all args values in method for unit test?

I'm stuck in a situation.

Below is the illustration of same.

I'm passing the values through argument parse. Values of a, b , c.

Code is -

initial_foo(args): **codes** args.a, args.b are used here.

If I print args, it returns self.args = argsparse.Namespace(a='hii',b='bye',c='yolo'). Now if I pass args in initial_foo(self.args) it automatically picks up the values provided through args.

Now, I want to test this initial_foo(args) method. So, probably I can do is that setting up the same self.args = argsparse.Namespace(a='hii',b='bye',c='yolo') and passing in initial_foo method. What if I don't want to use this.

Is there any other solution of the same ?

Anything which we can do through ```**locals() ?

Please let me know if you have any doubts.

If you are thinking on how to unittest the initial_foo without creating an argparse.Namespace object, then you could pass initial_foo any object which with properties 'a', 'b', 'c' and allows dot notation call.

locals() doesn't work because that gives you a dict. dictionary elements are accessed through index (__getitem__), not dot operator (__getattr__)

You could create a class, with these props and pass in an object of that class.

class Data(object):
    def __init__(self, a, b, c):
         self.a = a
         self.b = b
         self.c = c

initial_foo(Data(1,2,3))

Or pass in a named tuple

from collections import namedtuple
data = namedtuple('data', ['a', 'b', 'c'])
initial_foo(data(1,2,3))

Anything similar should work too.
