There are a lot of test sets that people use, like 'Win at Chess', and you can get a book with tactical problems (like Reinfeld's 1001 Winning Combinations and Sacrifices) and use that if you want. Also, I would run matches between the new version and the old version, and also between the new version and other programs. If you have old results for your old program against those same programs you can compare those results. The good thing about that is that you can let the match play automatically while you work or sleep, and you can play a lot of games and get a good idea of whether the new version is better or not.
