What is the test for determining the sufficiency of evidence in a sexual assault case?

" 'To determine the sufficiency of the evidence to support a conviction, an appellate court reviews the entire record in the light most favorable to the prosecution to determine whether it contains evidence that is reasonable, credible, and of solid value, from which a rational trier of fact could find the defendant guilty beyond a reasonable doubt.' [Citations.]" (People v. Wallace (2008) 44 Cal.4th 1032, 1077; Jackson v. Virginia (1979) 443 U.S. 307, 317-320 [61 L.Ed.2d 560, 572-574].) "In deciding the sufficiency of the evidence, a reviewing court resolves neither credibility issues nor evidentiary conflicts. [Citation.] Resolution of conflicts and inconsistencies in the testimony is the exclusive province of the trier of fact. [Citation.] Moreover, unless the testimony is physically impossible or inherently improbable, testimony of a single witness is sufficient to support a conviction. [Citation.]" (People v. Young (2005) 34 Cal.4th 1149, 1181.)
