[PATCH 11/21] testCompareXMLToArgv: Split out preparation and command formatting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are multiple steps of setting up the domain definition prior to
formatting the command line for the tests. Extract it to a separate
function so that it's self-contained and also will allow re-running the
command line formatting which will be necessary for QMP schema
validation tests.
