    chai-eventemitter

    1.1.1 • Public • Published

    chai-eventemitter NPM Version Build Status

    This is a plugin for chai to simplify the testing of EventEmitter.

    EventEmitters can be testing using spies, but they are rather heavyweight for most usecases:

    var spy = sinon.spy()
     
    ee.on('test', spy)
    ee.emit('test')
    expect(spy).to.have.been.called()
     
    spy.reset()
    ee.emit('test', args)
    expect(spy).to.have.been.calledWith(args)

    chai-eventemitter replaces this with something much more digestable:

    expect(function(){ ee.emit('test') }).to.emitFrom(ee, 'test')
    expect(function(){ ee.emit('test', arg) }).to.emitFrom(ee, 'test', arg)

    Setup

    node.js / io.js

    var chai = require('chai')
    chai.use(require('chai-eventemitter'))
