From 26f87181f8a8fc7fef58ddd1e52cb5f0edd641bb Mon Sep 17 00:00:00 2001 From: drebs Date: Thu, 7 Jul 2016 11:44:01 +0200 Subject: [test] toxify tests - move tests to root directory - split tests in different subdirectories - setup a small package with common test dependencies in /testing/test_soledad - add tox.ini that will: - install the test_soledad package and other test dependencies - install soledad common, client, server from the repository - run tests contianed in /testing/tests directory using pytest This commit also removes all oauth code from tests, as we have removed the u1db dependency (by importing it into the repo and naming it l2db) and don't neet oauth at all right now. --- testing/tests/sync/test_sync_target.py | 968 +++++++++++++++++++++++++++++++++ 1 file changed, 968 insertions(+) create mode 100644 testing/tests/sync/test_sync_target.py (limited to 'testing/tests/sync/test_sync_target.py') diff --git a/testing/tests/sync/test_sync_target.py b/testing/tests/sync/test_sync_target.py new file mode 100644 index 00000000..964468ce --- /dev/null +++ b/testing/tests/sync/test_sync_target.py @@ -0,0 +1,968 @@ +# -*- coding: utf-8 -*- +# test_sync_target.py +# Copyright (C) 2013, 2014 LEAP +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
