Hey guys, As part of my college thesis I was attempting to unit test libselinux-2.2.2-4 on Fedora 20 via Python (used unittest framework). I've created bunch of tests (60) for some labeling function but result is not very good. Decision coverage of code under test +-45%. Caused mostly by unability stub dependencies from C source code via Python. So tests looking more like integration/fuctional tests. I'm interested in your feedback if there is need for such a tests or its waste. Thank you. Add runner of testes and helper module which contains usefull func def. --- tests/helper.py | 69 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/runtests.py | 46 +++++++++++++++++++++++++++++++++++++ 2 files changed, 115 insertions(+) create mode 100755 tests/helper.py create mode 100755 tests/runtests.py diff --git a/tests/helper.py b/tests/helper.py new file mode 100755 index 0000000..8d588ff --- /dev/null +++ b/tests/helper.py @@ -0,0 +1,69 @@ +#!/usr/bin/env python + +#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.
