mongojs/test/test-streaming-cursor.js

Easy to use module that implements the mongo api

var insert = require('./insert')

insert('streaming cursor', [{
  hello: 'world1'
}, {
  hello: 'world2'
}], function (db, t, done) {
  var cursor = db.a.find()
  var runs = 0

  var loop = function () {
    var doc

    while ((doc = cursor.read()) !== null) {
      t.ok(doc.hello === 'world1' || doc.hello === 'world2')
      t.equal(typeof doc, 'object')
      runs++
    }

    cursor.once('readable', loop)
  }

  cursor.on('end', function () {
    t.equal(runs, 2)
    done()
  })

  loop()
})
