Generally testing involves giving a script values for whatever post/get/db variables its looking for (both valid and invalid values) and checking to see if I get expected behaviour. Behaviours can be in multiple forms including checking the visible markup (i.e. xhtml, javascript, css) as well as verifying data sent to or received from the db by using manual queries. As noted above this is all done on a test site so as not to pooch a live site.
