+1 for this. IMO all DAOs should be reachable from the CommandBase as
this is a repeated code scattered in the various commands.
I'd suggest to create an interface that declares all of available
DAOs.
The new interface should be implemented by both DbFacade (which
already
contains that implementation) and CommandBase to assure new DAOs
added
to DbFacade will be added to the CommandBase as well.
I'm not sure an interface is needed, since you won't be replacing it with
different implementations.
However, maybe a good approach is to put this method in bases class:
protected DbFacade getDbFacade() {
return DbFacade.getInstance();
}
This of course can be spied on to return a mock of the facade, and this mock can in turn
return whatever mock DAOs you need.

Searching for the static mocked classes brought the following list:
1 AuditLogDirector.class
1 CommandsFactory.class
1 FileUtil.class
1 LoggerFactory.class
1 QuotaHelper.class
1 QuotaManager.class
1 SchedulerUtilQuartzImpl.class
1 StopVdsCommand.class
1 TransactionSupport.class
1 VmTemplateCommand.class
2 CpuFlagsManagerHandler.class
2 StorageDomainSpaceChecker.class
2 VdsGroupDAO.class
3 EjbUtils.class
3 LogFactory.class
3 MultiLevelAdministrationHandler.class
3 StorageHelperDirector.class
3 VmTemplateHandler.class
6 ImagesHandler.class
6 VmHandler.class
10 Backend.class
28 Config.class
33 DbFacade.class
So handling the Config and DbFacade will be a major step toward
powermock elimination.
