I have been passing properties to Gatling using the gatling-maven-plugin for a long time and it works flawlessly. However, I have stumbled upon an issue that I cannot seem to get around:
I basically want to pass my setUp() from the command line to Gatling.
So this works:
numUsers = System.getProperty("mytest.numUsers").asInstanceOf[Int]
…however this does not:
pauseTime = Duration.apply(System.getProperty("mytest.pauseTime"))
To answer your first question, this excerpt is part of a case class, so no vals in the lines above.
Validating the code using the Scala console works fine - I can set the system property, read it back and apply the string and get a Duration without any issues. It is providing the duration as a string (“1 second”) on the command line that is a problem to me right now.
I have tried passing the following:
-Dmytest.pauseTime="1 second"
or…
"-Dmytest.pausetime=1 second"
Result:

Does anyone have any pointers for me here?
