Unit-test

We provide a simple package called hemera-testsuite to emulate a limited feature-set of a real NATS Server in-memory.

Features

• Support of wildcard * and > subjects
• Support for maxMessages$, expectedMessages$ options
• Support for request & publish
• Support for timeouts

Not supported*

• Custom queue groups
• Special one-to-one publish
• Load balancing
• Connection related states

*In this case we recommend to start a real NATS Server.

const Hemera = require('nats-hemera')
const Nats = require('hemera-testsuite/nats')
const nats = new Nats()
const hemera = new Hemera(nats)

hemera.ready(function() {
  hemera.add(
    {
      topic: 'math',
      cmd: 'add'
    },
    (req, cb) => {
      cb(null, req.a + req.b)
    }
  )
  hemera.act(
    {
      topic: math,
      cmd: add,
      a: 1,
      b: 2
    },
    (err, resp) => {
      console.log(err, resp)
    }
  )
})
