SSCCE for Gatling Community Support

Requirement

• Maven 3.5.x
• Java 8

How To Run

• mvn clean gatling:test -Dgatling.simulationClass=com.jak.sandbox.gatling.MySimulation -Denv.name=tst

Issue

• In my gatling.conf, I've one substitution defined which is set by command line system property (see above)

    directory {
      #simulations = user-files/simulations # Directory where simulation classes are located (for bundle packaging only)
      resources = src/test/resource/${env.name}     # Directory where resources, such as feeder files and request bodies are located (for bundle packaging only)
      #reportsOnly = ""                     # If set, name of report folder to look for in order to generate its report
      #binaries = ""                        # If set, name of the folder where compiles classes are located: Defaults to GATLING_HOME/target.
      #results = results                    # Name of the folder where all reports folder are located
    }

• Simulation fails at startup with following error

Expected

• When running simulation, env.name value should be substituted in gatling.conf.
• Works well with gatling 2.x. Check out the example with Gatling 2.x at this Github Repo
