What is the test for corroboration in a sexual assault case?

"corroborate every fact to which the accomplice testifies [citation], and ' "may be circumstantial or slight and entitled to little consideration when standing alone" ' " (People v. Romero and Self, supra, 62 Cal.4th at p. 32.) We find no basis for disrupting the jury's conclusion since there was abundant corroborating evidence. " 'The trier of fact's determination on the issue of corroboration is binding on the reviewing court unless the corroborating evidence should not have been admitted or does not reasonably tend to connect the defendant with the commission of the crime.' " (Id. at pp. 32-33.)
