[tor-commits] [nyx/master] Test _draw_platform_section()
commit 619cb2186fe67414c4ce1e49e7eb07821bdf24c8
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date: Sat Apr 9 21:48:37 2016 -0700
Test _draw_platform_section()
First test for our header panel. This requires our render() method to provide a
draw context but other than that straight forward.
I'm not a fan of the new _sampling() function. I'll change that when we add
tests for get_sampling().
