I don't think XP was the point of origin for either writing tests first or unit testing, as I have worked with teams where both practices were followed long before XP ever came on the scene. XP more or less just subsumed and/or modified many practices that its originators felt were the good ones under the umbrella namespace of Extreme Programming. Not that that detracts from XP or following the link you provided for more info.
