What is the test for admitting evidence of prior criminal activity against a defendant?

Finally, because we find no abuse of discretion in the trial court's determination that the limited evidence regarding the other gang crimes and the police investigation into the gang's criminal activities was relevant and more probative than prejudicial, we reject appellants' contention that the admission of this evidence violated their federal constitutional rights. (See Estelle v. McGuire (1991) 502 U.S. 62, 70 [defendant's due process rights not violated by admission of relevant evidence of prior acts against the victim].)
