Just is right.
But...
I struggled with coming up with something. The problem is that bar does
not exist in the right form unlee you are executing the function so:
def foo(_test = False):
r"""
>>> foo()
21
>>> foo(_test = True)
20
"""
def bar():
"""
>>> bar()
11
"""
print 10
print 20
if _test:
_locals = locals()
import doctest
g = globals().copy()
g.update(_locals)
g['__test__'] = {}
_totest = {}
for loc in _locals.values():
try:
if loc.__doc__ and loc.__name__ and (loc.__name__
not in g['__test__']):
_totest[loc.__name__] = loc
except:
pass
for _name, _testing in sorted(_totest.items()):
doctest.run_docstring_examples(_testing, g,
name = "foo:" + _name)
import doctest
doctest.testmod()
The output is:
Trying:
foo()
Expecting:

(but use a module instead)!
