Testing is very different to proving!
As an industry we do a lot of testing at many different levels.
On bigger projects you'll find:
- Unit tests - testing small fragments of a bigger program
- Integration tests - testing that sub modules of code work
  together (and code with hardware, if applicable)
- System testing - checking that the code(and hardware) as a
  whole does what it should based on the specs (often done
  by an independent team)
- Performance testing - checking the system runs as fast as it
  should, using only the memory it should, for as long as it should.
- User testing - Can a real user drive it?
- security testing - Does it stop the bad guys from messing it
  up or using it as a gateway?

And there are more levels if you are really keen.
Testing often(usually!) takes up more time than programming.
And there are many, many books written about how to do it.
