From 785fd9fa125a8f89a434fcb6e7624f599892e3a4 Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Mon, 23 Mar 2015 17:24:43 +0100 Subject: [PATCH] tests: qemuxml2xml: Refactor the qemuxml2xml test To allow adding more tests, refactor the XML-2-XML test so that the files are not reloaded always and clarify the control flow. Result of this changes is that the active and inactive portions of the XML are tested in separate steps rather than one test step. --- tests/qemuxml2xmltest.c | 214 ++++++++++++++++++++++++++-------------- 1 file changed, 140 insertions(+), 74 deletions(-) diff --git a/tests/qemuxml2xmltest.c b/tests/qemuxml2xmltest.c index 0f16d5ebc1..e6d4e6f046 100644 --- a/tests/qemuxml2xmltest.c +++ b/tests/qemuxml2xmltest.c @@ -22,11 +22,30 @@ static virQEMUDriver driver;
