JMeter - Cambiare utente variabili definite da linea di comando

Question

Sto cercando di aggiornare un "utente variabile definita" in un piano di test jmeter utilizzando la riga di comando

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

come potete vedere ho sto usando l'argomento -J. Tuttavia non sembra fare alcuna differenza? C'è un modo migliore/più accettato di passare in variabili diverse per un piano di test?

Ecco il mio file di JMX

Answer 1

Bene, con -J argomento che si sta configurando PROPRIETÀ, e in User Variabili definite config - VARIABILE. Definirà due entità diverse, pur avendo lo stesso nome, avranno valori diversi.

Nella tua situazione puoi fare quanto segue.

1. Imposta il valore della proprietà jmeter nella riga di comando come sopra nella tua domanda (...-Jtestproperty=202).

2. Nel variabile set di configurazione UDV con valore dalla proprietà:

   testproperty = ${__property(testproperty,,)}

   o

   testproperty = ${__P(testproperty,)}

3. Usa ${testproperty} ulteriormente nello script.

Così si può eventualmente fare lo stesso utilizzando wihout variabile e semplicemente fare riferimento proprietà come {__P(testproperty,)} per ottenere valore impostato in-linea di comando.
