problema al testear con blueJ , con rangos

[robertofd1995]

hola a todos , veran estoy en el primer año de carrera de informatica y el otro dia empezamos a hacer un test del programa con blueJ, con los metodos normales de mi programa , como fijar edad , nombre , genero , etc.. no tengo problema , el problema se me presenta cuando tengo que hacer el test de un metodo llamado crticalAge, que lo que hace es en funcion de los años que tengas , te dice si eres adulto , joven o retirado y los años que te quedan para la siguiente etapa , como hago para testear con esos rangos , os dejo aqui el codigo

la parte del critical age es esta :

/**
* this method tell you how many years you have left to be
* 1) adult ,if you are under 18
* 2) retired ,if you are under 67
* 3) you are retired
*/
public String getCriticalAge ()
{  
   
     if (age >0 && age <C_ADULT)
   return (C_ADULT-age)+" to be adult";
   else if ( age <=C_RETIRED && age >=C_ADULT)
    return (C_RETIRED-age+" to be retired");
       else
   return (age-C_RETIRED)+" you are retired" ;
   
 
               
}
