Setup

dummy = {}
    function setDummy (i) {
      dummy[i] = i + i + i
    }
    function readDummy (i) {
      return dummy[i]
    }
    function setLS (i) {
      localStorage.setItem(i, i + i + i)
    }
    function readLS (i) {
      return localStorage.getItem(i)
    }
    function makeSet (count) {
      var s = []
      for (var i = 0; i < count; i++) {
        s.push("" + i + i)
      }
      return s
    }
    set1 = makeSet(10)
    set2 = makeSet(100)

Teardown


    dummy = {}
    function clearLocalStorage (s) {
      for (var i = 0; i < s.length; i++) {
        localStorage.removeItem(s[i])
      }
    }
    clearLocalStorage(set1)
    clearLocalStorage(set2)
