Pls. describe it in detail with code

Have a look at this Tutorial, it desribes it much better than I could do
in a few lines. It's all about a crude way of programming by contract, i.e. you
'assert' that certain conditions are true before you start your method. You can
also check the correctness of your method by 'asserting' the results afterwards.

kind regards,
