What is the test for abuse of discretion in sentencing decisions?

"Sentencing choices such as the one at issue here, whether to reinstate probation or sentence a defendant to prison, are reviewed for abuse of discretion. `A denial or a grant of probation generally rests within the broad discretion of the trial court and will not be disturbed on appeal except on a showing that the court exercised its discretion in an arbitrary or capricious manner.' [Citation.] A court abuses its discretion `whenever the court exceeds the bounds of reason, all of the circumstances being considered.' [Citation.] We will not interfere with the trial court's exercise of discretion `when it has considered all facts bearing on the offense and the defendant to be sentenced.' [Citation.]" (People v. Downey (2000) 82 Cal.App.4th 899, 909-910.)
