What is the test for a pleading of a lesser included crime?

When the accusatory pleading describes a crime in the statutory language, as in the present case, the test for a lesser included offense is simply that where the charged "offense cannot be committed without necessarily committing another offense, the latter is a necessarily included offense." (People v. Greer (1947) 30 Cal.2d 589, 596, 184 P.2d 512, disapproved on other grounds in People v. Pearson (1986) 42 Cal.3d 351, 357-358, 228 Cal.Rptr. 509, 721 P.2d 595; People v. Lohbauer (1981) 29 Cal.3d 364, 369, 173 Cal.Rptr. 453, 627 P.2d 183.)
