How to check if variable exists in a Gatling session?

Question

In this question, an ObjectA creates a session variable, used in ObjectB

ObjectB will fail to execute if ObjectA fails to set the "GroupName" variable.

How to check in ObjectB context that session variable "GroupName" exists?

Answer 1

The gatling EL has support for checking if a variable exists in the session. so you can do something like this...

exec(ObjectA)
.doIf("${GroupName.exists()}") {
    exec(ObjectB)
}
