user30572: I have a need to generate a new extended public key (xpub).
Examples:

How can I do this?
I would like to do it inside json rpc, because that would help automate testing, but I ultimately don't care how I get them. They are for testing.

user51948: You can do that, but each HD seed needs to be inside its own wallet file which is loaded by the server. Running bitcoind with multiple -wallet arguments will achieve what you are aiming for. Currently it is not supported to dynamically load and unload wallets at runtime, but support for that is being added and will be available in a future release.

user30572: You can generate new extended public keys on
http://bip32.org/
You can generate them for testnet or mainnet. Just set the network combo box in the upper right to the network you want.

ADVISO: Please don't ever use websites to generate key material. Suitable only for throw-away addresses for testing only.
