Mock implementation of ExoComm in JavaScript

a mock implementation of ExoComm-Dev for sending and receiving messages to your ExoServices in test

Installation

$ npm i --save-dev exocomm-mock

Usage

• create an instance

  ExoCommMock = require('exocomm-mock')
  exocomm = new ExoCommMock
  

• register a service to send messages to

  exocomm.registerService name: 'users', port: 4001
  

• send a message to the service

  exocomm.sendMessage service: 'users', name: 'users.create', payload: { name: 'Jean-Luc Picard' }
  

• verifying messages sent out by the service under test

  # ... make your service sent out a request here via exocomm.sendMessage...
  
  # wait for the message to arrive
  exocomm.waitUntilReceive =>
  
    # verify the received message
    expect(exocomm.receivedMessages()).to.eql [
      {
        name: 'users.created'
        payload:
          name: 'Jean-Luc Picard'
      }
    ]
  

• if you want to verify more received messages later, you can reset the register of received messages so far

  exocomm.reset()
  

• finally, close your instance when you are done, so that you can create a fresh one for your next test

  exocomm.close()
