To start the worker node on your local machine, you can use the following command. This command sets the PORT environment variable to 7001 7002 ... as defined in coordinatorNode.js, which specifies the port number on which the worker node will listen, and then starts the worker node script located at ./test/workerNode.js.
PORT=7001 node ./test/workerNode.jsPORT=7001 node ./test/coordinatorNode.jsnpx jest ./test/coordinator.test.js
