[PATCH 15/19] qemuxml2xmltest: Introduce fake network driver
In order to be able to use '<interface type="network"' we need a
fake
network driver in qemuxml2argvtest. Create one by simply allowing users
to reuse configs from tests/networkxml2xmlin and tests/virnetworkportxml2xmldata
which will be returned to corresponding functions.
The driver implements:
.networkLookupByName = fakeNetworkLookupByName,
- validate syntax of network name, check if config exists
.networkGetXMLDesc = fakeNetworkGetXMLDesc,
- return appropriate XML
.networkPortCreateXML = fakeNetworkPortCreateXML,
- validate that port XML exists
.networkPortGetXMLDesc = fakeNetworkPortGetXMLDesc,
- return appropriate port XML
With the above and the correspondign test data, all network XMLs can be
enabled.
