doctests behave differently inside dreampie

[MikeyB]

Dreampie 1.0
Python sys.version_info: (2, 6, 2, 'final', 0)

Running the following code:
def demofunction(a, b):
    '''Simple demonstration function

    >>> demofunction(3, 4)
    7
    '''
    return a+b

import doctest
doctest.testmod()

results in:
Dreampie:
>>> doctest.testmod()
**********************************************************************
File "__main__", line 4, in __main__.demofunction
Failed example:
    demofunction(3, 4)
Expected:
    7
Got nothing
**********************************************************************
1 items had failures:
   1 of 1 in __main__.demofunction
***Test Failed*** 2 failures.
8: TestResults(failed=1, attempted=1)

Python shell:
>>> doctest.testmod()
TestResults(failed=0, attempted=1)

Thanks for the report!

It turns out that the problem is that doctest assumes that sys.displayhook just prints the value it gets into stdout, while DreamPie installs a different displayhook.

I filed a bug at http://bugs.python.org/issue8048 . In the meanwhile, you can replace your doctest.py file with the attached file, which fixes this bug.

Much better, thanks!
