JMeter - Changement de variables définies par l'utilisateur à partir de la ligne de commande

Je suis en train de mettre à jour une "variable définie par l'utilisateur" dans un jmeter plan de test à l'aide de la ligne de commande

jmeter -n -t SimpleJmxExample.jmx -l log.jtl -Jtestproperty=202

comme vous pouvez le voir je suis en utilisant l'argument-J. Toutefois, il ne semble pas faire une différence? Est-il mieux/plus moyen accepté de passer dans les différentes variables pour un plan de test?

Voici mon jmx fichier
