You have two choices. One is to make a kind of stub of your application, which will just handle testing plugins. Second is to make sure you unload the plugin before loading it again. I don't know if it works in all environments, but there is a chance that after unloading and loading the plugin again, you'll get the new plugin instead of the old one. Simply reloading the plugin won't do, as it'll see that it's already loaded and will just give you the old pointer.
