Can I unit test the DOM?

Question

We have a Ruby on Rails application that uses some javascript in views. Since we have good testing coverage in the rest of the application, we want to continue this here. The js we use manipulate the DOM to show / hide divs and perform an incremental search for combobox choices from the table.

Does anyone know how to test DOM manipulation?
