The job of automated testing is to reduce the cost of QA.
With proper project documentation and separation of backend from interface using DOM templating as well as a compartmentalised, non-monolithic application architecture (ie. not using "frameworks" in the traditional sence) the code that drives an interface is not only trivial to build but also pretty trivial to replace.
