expire-unused-keys/test/immediate_refresh.js

Who wants to keep track of what's not being used? This guy!

var Expirer = require('../')
var test = require('tape')
var level = require('level-mem')

test("Should fire a second time after being touched in an expire callback", function(t) {
	var expirer = new Expirer(500, level('wat'))
	var key = "lol I'm a key"

	expirer.emit('touch', key)

	t.plan(2)
	t.timeoutAfter(3000)

	var done = false

	expirer.once('expire', function() {
		t.pass('called the first time')
		expirer.touch(key)
		expirer.once('expire', function() {
			t.pass('called the second time')
			expirer.stop()
			done = true
			t.end()
		})
	})
})
