[libvirt] [PATCH v6 2/5] Network: Add regression tests for the command-line arguments
Michal Novotny
minovotn at redhat.com
Fri Jun 24 10:04:37 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).
Differences between v5 and v6 (this one:
- For the tests the pidfile is set to NULL string so there's
no --pidfile argument passed to the dnsmasq.
