Yes. 

Don't you have to test a statically typed program in each and every
branch to be sure you didn't forget something too?

Perhaps not, if you build the test suite as you build the
application. I agree that dynamically typed software without tests
can be a nightmare, but I think that statically typed code without
tests is almost as bad. In my experience the tests gives you the
security that a compiler will give you and much more. Plus it's easier
to write tests in python than let's say C++ which is the statically
typed language that I am most familiar with.

See www.xprogramming.com or http://c2.com/cgi/wiki?UnitTests for more
information on unit testing your code.
