s/settings/options/ here and elsewhere. We don't call it 'settings' in the code.

Done.

Why can't callers just call window.location.reload()?

Done.

[James Hawkins, 2011/07/08 00:03:33]

Why is this in |util|?

[Sheridan Rawlins, 2011/07/08 22:45:49]

Because of original generate all global functions.  Generation is now
declarative with TEST_F.

Are these asserts needed? If either of these conditions is false, item.onclick()
will log a JS error (which supposedly is an error in the test).

What's with this line?

[Sheridan Rawlins, 2011/07/08 22:45:49]

Not needed with subclassing of testing::Test - Can be done in PreLoad or SetUp
as needed.

[James Hawkins, 2011/07/08 00:03:33]

Why do you have to refresh the page after opening under the hood?

[Sheridan Rawlins, 2011/07/08 22:45:49]

The test is to ensure that refresh stays on the current page.  It was renamed
accordingly.

Move these vars to the top of the file and document them.

Not needed now that we have test_fixture to hold the variables.
