[Lldb-commits] [PATCH] D55835: [dotest] Consider unexpected passes as failures.

[Jonas Devlieghere via Phabricator via lldb-commits]

JDevlieghere added a project: LLDB.

Unexpected successes should be considered failures because they can hide regressions when not addressed. When a test is fixed and not re-enabled, it can easily regress without us noticing.

I couldn't find a good way to make this change other than changing it in the unittest2 framework. I know this is less than optimal but since we have the dependency checked in and the change is pretty fundamental to the framework I think it's not unreasonable.
