inject different level implementations (browser, leveldb, etc) into your tests.
Create a fresh db, with out refering to any fs or dom specifics, so that the same test can be used in the server or the browser!
var level = require('level-test')()
var db = level('foo', {encoding: 'json'})
var level = require('level-test')( { mem: true })
var db = level('foo', {encoding: 'json'})
use whatever test framework you like!
configure leveldb settings via command line options/enviroment vars.
