New submission from Jens Diemer <[EMAIL PROTECTED]>:
The doctest doesn't work good, if a function returns a dict.
Here a simple example:
def test(d):
"""
This works:
>>> test({"A":1, "B":2, "C":3})
{'A': 1, 'C': 3, 'B': 2}
This failed, because of different dict sort:
>>> test({"A":1, "B":2, "C":3})
{'A': 1, 'B': 2, 'C': 3}
The Error messages:
Failed example:
test({"A":1, "B":2, "C":3})
Expected:
{'A': 1, 'B': 2, 'C': 3}
Got:
{'A': 1, 'C': 3, 'B': 2}
"""
return d
The problem is IMHO that doctest.py [1] OutputChecker.check_output()
does compare the repr() of the dict and not the real dict as data.
One solution: Use eval() to convert the string repr. of the dict into
the real dict:
...
#-----<add>-----
try:
if eval(got) == eval(want):
return True
except:
pass #*pfeif* kein schoener stil, aber pragmatisch
#-----</add>----
# We didn't find any match; return false.
return False
