numbat-collector-mock

a mock numbat collector server for your tests

var numbat = require('numbat-emitter')

var collectorMock = require('numbat-collector-mock')

// connect and make the mocking server
var emitter = new numbat({uri:'tcp://localhost:3333',app:'test'})
var collector = numbatMock()


// send a metric
emitter.metric({
  name:"foo"
})

// get the results
collector.finished(function(err,metrics){
  console.log(metrics[0].name === 'test.foo')
})

Test that your application code is sending the metrics you intend.

api

module.exports = collectorMock([port)

• port
  • optional. defaults to 3333
• returns Collector

Collector

• collector is a stream. it emits data events for each metric it receives.

Collector.finished(callback)

• callback - function(err,metrics).
  • this is trigered when metrics should have been received.
  • err
    • an error may be triggered if numbat-emitter fails to connect to the mock server at all.
  • metrics
    • and array containing each metric sent from numbat-emitter
• returns nothing.

Use this function after your code should have passed metrics to numbat-emitter. it will carefully handle the callback so it get's triggered at the right time. It will dispose of the server and close any numbat-emitter connections so that you can get a clean start for the next test.
