Optional arguments #37

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Related to issue 12, I want to stub out a function with optional arguments. I 
can't know in advance whether the optional arguments will be provided or not.
IgnoreArg() is no help with missing arguments.

def bar(one, two=None):
  pass

The test subject may call
bar(1)
or
bar(1, two=None)
or
bar(1, None)
or
bar(1, 42)

I'd like to be able to do
bar(1, two=IgnoreArg())
and have it match all of the above.

Mox is intended to be used for deterministic tests.

Why can't you know in advance what your code is going to do?

OK, I only really need the first two examples above.

I have to stub out a function in another library for a test, and there are 
multiple versions of this library in production. The new version passes 
two=None, the other doesn't.
