Mock implementation of ExoCom in JavaScript

Dependency Status devDependency Status

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()
