What is the test for determining the credibility of a witness?

In determining whether there is sufficient evidence to support a jury's findings, we review the entire record in the light most favorable to the prosecution to see if any rational trier of fact could have been so persuaded. (People v. Hovarter (2008) 44 Cal.4th 983, 996-997.) It is the exclusive province of the trier of fact to determine the credibility of a witness and to resolve evidentiary inconsistencies, and we must defer to the factfinder's credibility resolutions. (People v. Young (2005) 34 Cal.4th 1149, 1181.) " 'It is blackletter law that any conflict or contradiction in the evidence, or any inconsistency in the testimony of witnesses must be resolved by the trier of fact who is the sole judge of the credibility of the witnesses.' " (People v. Watts (1999) 76 Cal.App.4th 1250, 1258, quoting People v. Ozene (1972) 27 Cal.App.3d 905, 910.)
