Thanks for making this file! Nicer to review it once.

Use a different item name for each test so they don't interfere with each other.

I have changed this file such that both reloads now happen in the same file.
Easier to see everything in one go.

+        window.localStorage.clear();

[jkarlin, 2016/04/14 18:24:38]

localStorage is storage per-origin. So if other tests are running clear() would
wipe them out as well. So instead, it's best to delete just the item. 

Also, you want to clear this at the end of the test regardless of success or
failure.
