Local Dev Cluster

If you don't have an enterprise license key, but you want to try NBomber Cluster you can run it in development mode. Local Dev Cluster gives you a fully-fledged cluster — with a few limits (see below) — and is handy for developing and testing scenarios in a cluster without dealing with license keys.

info

Local Dev Cluster has two limitations compared to the licensed cluster mode:

  • The cluster size is limited to 3 nodes: 1 Coordinator + 2 Agents.
  • Each test run auto-stops after 1 minute.

This is enough for development or a POC. An Enterprise license removes both limitations, letting you run an unlimited number of Agents with no time limit.

Prior to NBomber 6.5.0, the cluster size limit was 2 nodes: 1 Coordinator + 1 Agent.

Example:

var scenario = Scenario.Create("test_scenario", async context => { ... });

NBomberRunner
    .RegisterScenarios(scenario)
    .LoadConfig("autocluster-config.json")
    .EnableLocalDevCluster(true)
    .Run();

Run Local Dev Cluster via CLI​

Another option to run Local Dev Cluster is via using CLI arguments: --cluster-local-dev=true

MyLoadTest.dll --config="autocluster-config.json" --cluster-local-dev=true
