user1760: Can I use the wallet functionality in bitcoin cli daemon with P2SH segwit on testnet/regtest? Meaning, can I receive on these addresses and send from them?
And if I can, how? 
I cannot find it anywhere in the help. The only one that gets close is addwitnessaddress, but that does something else, too.

user12983: addwitnessaddress is what you want
create it, fund it and spend coins from it - then check your transactions on any blockexplorer that they are in segwit format
