What is the legal test for an allegation of an attempted murder?

"In addressing a challenge to the sufficiency of the evidence supporting a conviction, the reviewing court must examine the whole record in the light most favorable to the judgment to determine whether it discloses substantial evidence evidence that is reasonable, credible and of solid value such that a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt. [Citation.] The appellate court presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence. [Citations.] The same standard applies when the conviction rests primarily on circumstantial evidence. [Citation.]" (People v. Kraft (2000) 23 Cal.4th 978, 1053.)

"An attempt to commit a crime consists of two elements: a specific intent to commit the crime, and a direct but ineffectual act done toward its commission." ( 21a.) "'It is... well settled that there is a material difference between the preparation antecedent to an offense and the actual attempt to commit it. The preparation consists of devising or arranging the means or measures necessary for the commission of the offense, while the attempt is the direct movement toward its commission after the preparations are made. In other words, to constitute an attempt the acts of the defendant must go so far that they would result in the accomplishment of the crime unless frustrated by extraneous circumstances. [Citations.]' [Citations.]" (People v. Memro (1985) 38 Cal.3d 658, 698.)
