What is the test for a motion for a new trial based on newly discovered evidence?

"In ruling on a motion for new trial based on newly discovered evidence, the trial court considers the following factors: ' "1. That the evidence, and not merely its materiality, be newly discovered; 2. That the evidence be not cumulative merely; 3. That it be such as to render a different result probable on a retrial of the cause; 4. That the party could not with reasonable diligence have discovered and produced it at the trial; and 5. That these facts be shown by the best evidence of which the case admits." ' " (People v. Delgado (1993) 5 Cal.4th 312, 328.)

" 'A motion for new trial on the ground of newly discovered evidence is looked upon with disfavor. [Citation.] The granting or denial of such a motion is within the sound discretion of the trial court and, absent a clear showing of abuse of discretion, will not be reversed on appeal.' " (People v. Shoals (1992) 8 Cal.App.4th 475, 485-486, disagreed with on another ground by People v. Fielder (2004) 114 Cal.App.4th 1221, 1231.) "The claim of newly discovered evidence warranting a new trial is universally looked upon by the courts with distrust and disfavor. Public policy demands that a litigant should be compelled to exhaust every reasonable effort to produce at his trial all existing evidence in his behalf. It has been said that the circumstance that the testimony has just been discovered when it is too late to introduce it is so suspicious that courts require the very strictest showing of diligence." (People v. Byrne (1911) 160 Cal. 217,
