What is the test for admitting a witness's testimony at trial?

as a witness and: [] ... [] (2) The party against whom the former testimony is offered was a party to the action or proceeding in which the testimony was given and had the right and opportunity to cross-examine the declarant with an interest and motive similar to that which he has at the hearing." ( Evid. Code, 1291, subds. (a), (a)(2).) We have held this exception permits an unavailable witness's preliminary hearing testimony to be admitted at trial.
