One thing I would recommend is refactoring your game to keep the game 
logic distinct from the I/O.

If I was designing this, I would have some sort of game engine class, 
which stores all the state for a game.  I imagine the first thing you 
need to do is pick a random number and remember it.  Then, you'll need a 
function to take a guess and tell you if it's too high, too low, or 
correct.  Something like:

class NumberGuessingGame:
   def __init__(self):
      self.number = random.randint(0, 10)

   HIGH = 1
   LOW = 2
   OK = 3

   def guess(self, number):
      if number > self.number:
         return self.HIGH
      if number < self.number:
         return self.LOW
      return self.OK

Now you've got something that's easy to test without all this pexpect 
crud getting in the way.  Then, your game application can create an 
instance of NumberGuessingGame and wrap the required I/O operations 
around that.

I'd also probably add some way to bypass the random number generator and 
set the number you're trying to guess directly.  This will make it a lot 
easier to test edge cases.
