I'm sorry, but I've seen both sides of the coin here and think that in the right situations, having a suite of automated-tests to give you confidence in an application is invaluable. Especially when you consider the alternative, which is hours wasted debugging. Sure writing tests can be hard, but it will make you write better, more modular code.

If you really do need to just get something out the door that quick, then you should just be prepared to accept the consequences of no tests, or put some in later for maintenance sake.
