commit b97f646c072352187b3f67e5059afe7668499b00 Author: Isis Lovecruft <isis@torproject.org> Date: Fri Dec 5 23:08:13 2014 +0000 Refactor old test_Bridges.py tests into test_bridges.py equivalents. The changes were very minor, mostly just replacing 's/Bridges\.Bridge/bridges\.Bridge/'. The old test_init() integration test was separated into six new tests, test_integration_init_[0-6]; all other integration tests have one-to-one correspondents with only trivial changes. --- lib/bridgedb/test/test_Bridges.py | 200 -------------------------- lib/bridgedb/test/test_bridges.py | 283 +++++++++++++++++++++++++++++++++++++ 2 files changed, 283 insertions(+), 200 deletions(-) diff --git a/lib/bridgedb/test/test_Bridges.py b/lib/bridgedb/test/test_Bridges.py deleted file mode 100644 index 2c7d09b..0000000 --- a/lib/bridgedb/test/test_Bridges.py +++ /dev/null @@ -1,200 +0,0 @@ -# -*- coding: utf-8 -*- -# -# This file is part of BridgeDB, a Tor bridge distribution system. -# -# :authors: please also see AUTHORS file -# :copyright: (c) 2007-2014, The Tor Project, Inc. -# (c) 2007-2014, all entities within the AUTHORS file -# :license: 3-Clause BSD, see LICENSE for licensing information -
