How to use the abstract-leveldown/abstract/leveldown-test.args function in abstract-leveldown

function leveldown (location) {
  iDB += 1
  var loc = location && [location,iDB].join('/')
  var dd = DynamoDown(loc)
  dd.oldOpen = dd._open
  dd._open = function(opts, cb) {
    opts.createIfMissing = true
    opts.dynamo = dynOpts
    return dd.oldOpen(opts, cb)
  }
  return dd
}
