I used to get code back from developers EACH AND EVERY TIME with massive bugs like: unable to register, unable to login, unable to add content. I wrongly assumed that they at least ran through and checked for any bugs they introduced before sending me the new code. So each and every time I got code back I had to go through manually and check it, sign in, log out, register, add content, delete content, edit content, add category, etc...

I wish someone could make a simple service that allows me to set up my web app, set up test parameters that it tests each and every time, and tell me if it failed or not. I want to automate my babysitting.
