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.
Great. Going to check it.
Also do you think there is a way how to generate DOC from these tests?
I mean I would like to create DOC? I mean I would like to see something like
setfilecon_raw(file, raw_con)
file="/tmp/test"
raw_con = "system_u:object_r:user_home_t:s0"
setfilecon_raw("/tmp/test","system_u:object_r:user_home_t:s0")
For each function. Basically the point is people don't know how to use
python bindings for libselinux.
But at least these tests (probably more integration/fuctional tests as
you wrote) are great examples for them.
So I will check them later this week and I don't have a problem to add
them if it looks OK.
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.
