I'd suggest to remove the random test and keep the non-random test in
the doc. I see no reason for hiding it.
Another possibility to deal with randomness of string representation:
Explicitly assign the expected result to a variable in the doctest, and
test for equality (here I assume that you have a function/method
returning a dictionary. Hence, for testing method "bar" of instance
"Foo", you could do
sage: D = {'a': 'b', 'x': 'y'}
sage: D == Foo.bar(pi)
True
But testing against sorted(dict.iteritems()) is perfectly fine in the
docs (of course it needs to be the case that the sorting of the
dictionary keys is non-random).
Best regards,
Simon
