What is the test for a motion for a mistrial?

"'"'[A] mistrial should be granted if the court is apprised of prejudice that it judges incurable by admonition or instruction. [Citation.] Whether a particular incident is incurably prejudicial is by its nature a speculative matter, and the trial court is vested with considerable discretion in ruling on mistrial motions.'"'" (People v. Leavel (2012) 203 Cal.App.4th 823, 831.) We review the trial court's denial of defendant's mistrial motion for an abuse of discretion. (Ibid.)
