Clase de test local
Para crear una clase como clase de test, tenemos que añadir las palabras claves FOR TESTING en la definición de la clase.
CLASSlcl_test DEFINITION FOR TESTING.

METHODStest_factorial FOR TESTING.
ENDCLASS.
Para definir un método de test, tenemos que añadir las mismas palabras claves FOR TESTING en la declaración del método.
En un programa ejecutable, creamos la clase local LCL_CALCULADORA con el método de instancia SUMA que devuelve la suma de dos números. Creamos una clase de test para testear el método.
