Hi, Common practice is to write unit tests against known test data, rather than against unknown production data.
That way you could compare the actual values returned. When doing testing against unknown data you are limited to whatever extra checks you can make: * is the correct number of items returned * do all of them contain count greater than 0 * are they all sorted in (alphabetical | count) order Linas On Sun, Nov 20, 2011 at 3:31 AM, Todong <[email protected]> wrote: > Hi,all > > The Item can be viewed by visitor, the viewed counter will be saved in > database table(e.g. Items table).
