What is the test for a conviction for assault with a deadly weapon?

Appellant first contends that his conviction for assault with a deadly weapon is not supported by substantial evidence. He argues that his conduct more resembled exhibiting a deadly weapon in a threatening manner ( 417, subd. (a)(1)). The inquiry is whether, viewing the record in the light most favorable to the judgment, there is substantial evidence such that a rational, reasonable trier of fact could find appellant guilty beyond a reasonable doubt. (People v. Johnson (1980) 26 Cal.3d 557, 578.)
