What is the test for finding that a prosecutor's conduct violates the Fourteenth Amendment?

"A prosecutor's conduct violates the Fourteenth Amendment to the federal Constitution when it infects the trial with such unfairness as to make the conviction a denial of due process. Conduct by a prosecutor that does not render a criminal trial fundamentally unfair is prosecutorial misconduct under state law only if it involves the use of deceptive or reprehensible methods to attempt to persuade either the trial court or the jury. Furthermore, and particularly pertinent here, when the claim focuses upon comments made by the prosecutor before the jury, the question is whether there is a reasonable likelihood that the jury construed or applied any of the complained-of remarks in an objectionable fashion." (People v. Morales (2001) 25 Cal.4th 34, 44.)

"As a general rule a defendant may not complain on appeal of prosecutorial misconduct unless in a timely fashionand on the same groundthe defendant made an assignment of misconduct and requested that the jury be admonished to disregard the impropriety [Citation.] Additionally, when the claim focuses upon comments made by the prosecutor before the jury, the question is whether there is a reasonable likelihood that the jury construed or applied any of the complained-of remarks in an objectionable fashion." (People v. Samayoa (1997) 15 Cal.4th 795, 841.)
