Preventing network access during nose doctest ?

[Olivier Berger <olivier.berger@telecom-sudparis.eu>]

Hi.

I'm trying to fix #739222 where tests fail (-> FTBFS) during execution
of nose's doctest plugin on something like :
    >>> import rdflib

    >>> g = rdflib.Graph()
    >>> result = g.parse("http://www.w3.org/2000/10/swap/test/meet/white.rdf";)

    >>> print("graph has %s statements." % len(g))
    graph has 19 statements.

I'm puzzled : I'm invoking the tests run with :
	PYBUILD_SYSTEM=custom \
        PYBUILD_TEST_ARGS="{interpreter} run_tests.py" \
	http_proxy= https_proxy= \
	dh_auto_test --buildsystem=pybuild

where run_tests.py will invoke nose with --with-doctest, but even though
the HTTP proxy variables being set, they don't seem to be preventing
urllib2 to try to access the file.

So there doesn't seem to be a way to notice until the network is really
brought down :-/

Instructions at https://wiki.debian.org/Python/Pybuild suggest that the
variables help, but probably only for pip etc. ?


In any case, an obvious fix here could be to prevent running doctest at
all.

But there might be a smarter way, to fake the existence of such a page
(retrieved through urllib2) so as the tests can be run offline ?

If anyone has suggestions...

Many thanks in advance.

Best regards,
