Many of our Infusion components have functionality that cannot adequately be tested by jqUnit-style "in-browser" tests. There are hard limits on fidelity of simulation of browser primitives such as keystrokes, mouse movements, tab navigation, etc. An upcoming W3C API, webdriver - https://www.w3.org/TR/webdriver/ - and some concrete implementations such as http://www.seleniumhq.org/projects/webdriver/ promise to make it easier to deliver portable tests that verify these operations.

We should collect together a list of functions that we have been used to only be able to check during manual QA (for example, mouse operation of the reorderer, tab navigation of keyboard-a11y, etc.) and write comprehensive webdriver tests for these, allowing us to move Infusion releases to a much more rapid schedule.
