commit 9a4c98a72cda5bbd440282123a2a4a073cadd5c8 Author: Isis Lovecruft <isis@torproject.org> Date: Fri Dec 20 02:45:47 2013 +0000 Add test_Tests.monkeypatchTests() to setup regression tests. This function creates a `twisted.python.monkey.MonkeyPatcher` which will add deprecated code from `bridgedb.test.deprecated` back in, so that a TestCase class can run its tests on pre-refactored code to test for regressions. --- lib/bridgedb/test/test_Tests.py | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) diff --git a/lib/bridgedb/test/test_Tests.py b/lib/bridgedb/test/test_Tests.py index b898cc4..2532be1 100644 --- a/lib/bridgedb/test/test_Tests.py +++ b/lib/bridgedb/test/test_Tests.py @@ -22,9 +22,12 @@ import logging import os import warnings +from twisted.python import monkey from twisted.trial import unittest from bridgedb import Tests +from bridgedb.test import deprecated + logging.warnings.filterwarnings('ignore', module="Tests") pyunit = __import__('unittest') @@ -57,6 +60,36 @@ def generateTrialAdaptedDoctestsSuite(): globs=fakedGlobals)) return testSuites +def monkeypatchTests(): + """Monkeypatch the old unittests, replacing new, refactored code with their + original equivalents from :mod:`bridgedb.test.deprecated`. + + The first patch replaces the newer parsing function, + :func:`~bridgedb.parse.networkstatus.parseALine`, with the older, + :func:`deprecated one <bridgedb.test.deprecated.parseORAddressLine>` (the + old function was previously located at + ``bridgedb.Bridges.parseORAddressLine``). + + The second patch replaces the new :class:`~bridgedb.parse.addr.PortList`, + with the :class:`older one <bridgedb.test.deprecated.PortList>` (which + was previously located at ``bridgedb.Bridges.PortList``). + + The third, forth, and fifth monkeypatches add some module-level attributes + back into :mod:`bridgedb.Bridges`. + + :rtype: :class:`~twisted.python.monkey.MonkeyPatcher` + :returns: A :class:`~twisted.python.monkey.MonkeyPatcher`, preloaded with + patches from :mod:`bridgedb.test.deprecated`. + """ + patcher = monkey.MonkeyPatcher() + patcher.addPatch(Tests.networkstatus, 'parseALine', + deprecated.parseORAddressLine) + patcher.addPatch(Tests.addr, 'PortList', deprecated.PortList) + patcher.addPatch(Tests.bridgedb.Bridges, 'PORTSPEC_LEN', 16) + patcher.addPatch(Tests.bridgedb.Bridges, 're_ipv4', deprecated.re_ipv4) + patcher.addPatch(Tests.bridgedb.Bridges, 're_ipv6', deprecated.re_ipv6) + return patcher + class OldUnittests(unittest.TestCase): """A wrapper around :mod:`bridgedb.Tests` to produce :mod:`~twisted.trial`
