If you want to verify your custom plug-ins, you can deploy the plug-ins first on your local vSphere Client. You must register your local instances of the Web browser applications with the vCenter Server Appliance or vCenter Server for Windows to be able to deploy your plug-ins locally.

There are two options available to register your local vSphere Client. The automatic registration option applies only to the vCenter Server Appliance. The manual registration option applies to either the vCenter Server Appliance or to vCenter Server for Windows.
