Looking for regression testing package

[Marcus Leech]

We're looking for a package to do regression testing of packages we get
  from third party prior to releasing them to our user population.  We'd
  like something that can (using a script) simulate a human typing on the
  keyboard.  I'm aware of "expect/tcl"--are they appropriate?  Is there
  anything better?
