How to test excel compatibilities ?:- I want to know what to test other than trying to open some excel files with 40-50 thousand records on different versions of excel... my application generates excel reports....
I suggest you grab a copy of "How to Break Software" by James Whittaker. He has spent a lot of time breaking Excel and other Windows Applications.
Also do a search at Google for "Breaking Excel", it's amazing what you can find on the Web!
Success is the ability to go from one failure to another with no loss of enthusiasm.
