Raw Blame History

From a8f8ac6519aa46c4514c0f16073c2c6a7cb48a6a Mon Sep 17 00:00:00 2001
From: Benjamin Marzinski <bmarzins@redhat.com>
Date: Tue, 9 Jul 2019 16:31:25 -0500
Subject: [PATCH] tests: add path grouping policy unit tests.
In preparation for changing the path grouping code, add some unit tests
to verify that it works correctly. The only test that currently fails
(and so it being skipped) is using MULTIBUS when mp->paths is empty. All
the other path grouping policies free mp->paths, even if it is empty.
one_group() should as well. This will be fixed when the path grouping
code is updated.
