The aim of the project is to allow load testing of applications using ZeroMQ with the help of the Gatling tool.

SBT dependency:

"com.softwaremill.gatling-zeromq" %% "gatling-zeromq" % "0.1.0"

Gradle dependency:

"com.softwaremill.gatling-zeromq:gatling-zeromq_2.11:0.1.0"

gatling-zeromq is available for Scala 2.11 and requires Java 8.

You need to add a dependency on Gatling tool to your project since it is not bundled in this library.

Tests in the project can be started with:

sbt gatling:test

For more information look at the Gatling SBT plugin.

The project uses JeroMQ as the ZeroMQ connector.

Before running a scenario, you have to provide host and port to connect to. For example:

  val config = zmqConfig
    .host("localhost")
    .port("8916")

The plugin supports:

• the publishing side of the PUB-SUB pattern (zmqPub("...")),
• the requesting side of the REQ-REP pattern (zmqReq("...")),
• and the pushing side of the PUSH-PULL pattern (zmqPush("...")),

Sending of a message and a multi-part message is supported:

scenario("Scenario A")
    .exec(
        zmqPub("a request")
            .send("a message")
    )

scenario("Scenario B")
    .exec(
        zmqPub("a request")
            .sendMore("a multi")
            .sendMore("part")
            .send("message")
    )

Types of data can be String, Array[Byte], numeric ones and Gatling's Expression Language strings as well.
