The idea that you as you modify or change software, you test it
(usually automatically) to ensure that it still does the things it
used to do, and correctly. There's a whole body of computer science
devoted to regression testing, with analyses of which tests you
should do and which you can do without as the number of tests
invariably grow as the software ages.

Software that works from the command-line is of course most easily
tested. Embedded code, windows code, etc, is tougher.

Do a google search and you'll find some interesting sites.
