What is the test for establishing a prima facie case in a jury trial?

"In deciding whether a prima facie case was stated, we consider the entire record before the trial court [citation], but certain types of evidence may be especially relevant: '[T]he party may show that his opponent has struck most or all of the members of the identified group from the venire, or has used a disproportionate number of his peremptories against the group. He may also demonstrate that the jurors in question share only this one characteristic their membership in the group and that in all other respects they are as heterogeneous as the community as a whole. Next, the showing may be supplemented when appropriate by such circumstances as the failure of his opponent to engage these same jurors in more than desultory voir dire, or indeed to ask them any questions at all. Lastly, . . . the defendant need not be a member of the excluded group in order to complain of a violation of the representative cross-section rule; yet if he is, and especially if in addition his alleged victim is a member of the group to which the majority of the remaining jurors belong, these facts may also be called to the court's attention.' " (People v. Bonilla, supra, 41 Cal.4th at p. 342.)
