Configuration changes before {}

The following code seems to have no effect

before {
System.setProperty(“http.ahc:requestTimeout”, “10”)
setUp { …


I don’t know whether the property key is wrong, whether it is too late to change the configuration once the program is running, or if there is another way.



Actually, the syntax should be as follows, but it is still not detected

System.setProperty(“gatling.http.ahc.requestTimeout”, “10”)


That’s too late, the configuration is already loaded.
You have to pass them to the JVM on start up.

Thanks Stéphane for this confirmation.
