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

"'When the sufficiency of the evidence is challenged on appeal, the court must review the whole record in the light most favorable to the judgment to determine whether it contains substantial evidencei.e., evidence that is credible and of solid valuefrom which a rational trier of fact could have found the defendant guilty beyond a reasonable doubt.' [Citations.]" (People v. Jennings (1991) 53 Cal.3d 334, 364.) "When undertaking such review, our opinion that the evidence could reasonably be reconciled with a finding of innocence or a lesser degree of crime does not warrant a reversal of the judgment." (People v. Hill (1998) 17 Cal.4th 800, 849.)
