File 0105-Regression-tests.patch of Package btrfsprogs
From 8ed24be618165f2f76851e007347408ab9013d30 Mon Sep 17 00:00:00 2001 From: Hugo Mills <hugo@carfax.org.uk> Date: Thu, 27 Oct 2011 22:14:26 +0100 Subject: [PATCH 06/35] Regression tests Add a shell-script based test harness for performing regression tests on btrfs tools. This is not intended as a test system for kernel issues, but instead to put the userspace tools through their paces. Currently implemented tests are compilation of all tools, and checking argument counting on "btrfs sub snap". Other tests will follow.
