The global variables serve to keep track of which devices have been initialized. Devices can't be re-initialized, so I think the initialized devices would have to either be tracked through static class members or exist outside the test fixture to persist across tests. I don't *think* there's a way to check if a device has been initialized through the functions defined in PluginAPI.h, but I definitely could be overlooking something.
