Since my CL adding LoadBrowserTestJavaScript is already CQ'd, you might as well
wait until it lands and call that instead of loading browser_test.js explicitly
(though you don't technically need all the files it loads, it will make this
test more robust to refactorings of browser_test.js).

Acknowledged.

We should have two tests here: one to check that an invalid "cloud id" causes a
failure, and one to check that an invalid PIN causes a failure. It can be a
follow-up CL, because doing it in a robust way is somewhat involved because we
don't want this test to have knowledge of how the PIN is composed (we'll
probably have to call out to JS to decompose the string we extract from the DOM
and to recompose it after corrupting it). As you pointed out off-line, we should
probably modify the directory server to have a specific "cloud id" reserved for
testing so that we don't run the risk of accidentally picking a valid one.
