i want to design testcases on Orthogonal Arrays
who could tell me some information about this,for example ,the arithmetic of Orthogonal Arrays,the application of Orthogonal Arrays and so on.
thanks a lot!!
lee gives one of the best descriptions, Ward Cunningham also has a good one on the web and if my memory serves me well, it can be found on the wikipedia.
As for explaining them myself - done that before only to find my understanding was not as good as I though so I demure.

Do a search on Stickyminds.com for it. There are a few articles that may help you out. One article that was helpful is "Orthogonally Speaking" by Elfriede Dustin. I tried to add the link to the article but I guess I did not do it right. Anyway this article gives a good review of Orthogonal Array testing.
