Currently the system tests rely on three virtualhost (namely test, development and localhost) being defined in the system test configuration. This arrangement has the disadvantage that each system test must initialise three virtual hosts and for persistent stores (derby/BDB), this adds significant time to the test run. On the whole, tests use only the 'test' virtualhost.
This change will remove the dependency on the development and localhost virtual hosts. It will also remove the remaining few dependencies on the hardcoded queues "ping" and "queue".
In addition to the time saving, this change will help when we come to eliminate the configuration files entirely.
