Dynamic Payload

This project also demonstrates the integration between Java Protobuf messages with Gatling Expressions.

val message: Expression[Ping] =
  Ping.getDefaultInstance
    // dynamic payload!
    .update(_.setData)($("data"))

_.setData is a method reference of Ping.Builder; and
data is a session attribute containing a number.
