exocom-mock

Mock implementation of ExoCom in JavaScript

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

Installation

$ npm i --save-dev exocom-mock

Usage

• create an instance

  ExoComMock = require('exocom-mock')
  exocom = new ExoComMock
  

• register a service to send messages to

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

• send a message to the service

  exocom.sendMessage service: 'users', name: 'users.create', message-id: '123', payload: { name: 'Jean-Luc Picard' }
  

• verifying messages sent out by the service under test

  # ... make your service sent out a request here via exocom.sendMessage...
  
  # wait for the message to arrive
  exocom.waitUntilReceive =>
  
    # verify the received message
    expect(exocom.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

  exocom.reset()
  

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

  exocom.close()
