[libvirt] [PATCH v5 2/5] Network: Add regression tests for the command-line arguments

Michal Novotny minovotn at redhat.com
Tue Jun 14 13:02:45 UTC 2011


The regression testing done by comparison of command-line
generated from the network XML file and the expected
command-line arguments (read from file).

For the tests the pidfile should be set to NULL string, i.e.
(null) since no real invocation of the command is being done,
just the command-line is being generated and compared to the
expected one.
