Gatling is based on Scala, so you may want to install a Scala plugin for your IDE. Make sure the Scala version matches the one used in the project (
2.11.* at the time of this writing).
Run Magnolia webapp
/ as application context (found under Run Configurations > Deployment in IntelliJ) and run installation tasks if necessary.
Load test application configuration
In IntelliJ, create a new application configuration with the following properties:
-DsimulationName=findbar-masses -DsimulationClass=info.magnolia.loadtest.simulation.FindBarMassSimulation -Dgatling.test.instance=http://localhost:8080
This is an example to run
FindBarMassSimulation - for others, adjust as needed.
Use classpath of module:
Run load test
Once the Magnolia webapp is up and running and the load test application has been properly configured, it can be executed.
A successful run will continuously print statistics to the output, similar to the following snippet:
In order to observe memory consumption during different load tests, you can attach an external profiler like VisualVM. Just attach the profiler to the running Magnolia webapp server (most likely Tomcat) and observe its behavior while the load test application is running against that.
