Gatling is nice load testing framework that uses Scala, Akka and Netty. It’s so much better than JMeter. It’s pretty easy to get started with scenarios written in a nice Scala DSL and it produces useful reports too. It also has a Maven plugin so you can incorporate continuous performance testing in your builds.
The trouble is if you list multiple scenarios in a simulation they will all run concurrently which is probably not what you want. You need to split your tests into separate Simulation classes and run them sequentially. The plugin documentation briefly describes a way of doing this using executions but the example is a little light.
Here’s a Maven profile that when activated will run your simulations sequentially. Execute the tests with
mvn test -Pperformance.
