This server mocks some of the back end servers to load test our load balancer without the need for expensive backend servers. We have two implementations currently: Java and Node.js.

Java

Currently only the async vrp endpoint is mocked: https://docs.graphhopper.com/#operation/asyncVRP

Build

mvn clean package

Run with Java

java -jar target/fake-server.jar [-conf vertx.json]

Run with Docker

docker run -p 8080:8080 graphhopper/graphhopper-load-test-fake-backend

Run with Docker Compose

docker-compose up

Example Configuration

Default port 8080 can be overwritten in the configuration:

{
  "http.port" : 4321
}

Node.js

To run the server in Node.js, run the following:

docker run -d --rm --network host --name vrp-fake -v "$PWD"/node:/usr/src/app -w /usr/src/app node:8 node server.js [port]

This will run a Node 8 Docker container, pass in the node/server.js file and run that on the selected port.
