Ok, sure.
Here are some ideas.
As mentioned before, the Mother of All Book Tests (MOABT) by Ted Karmilovitch.
For a walkaround booktest: Try Luna from Outlaw Effects.
For an impromptu booktest: Try Alain Nu's Work Works II (But get Work Works I as well, although that's not impromptu, but still brilliant).
For a recent booktest: Try Devin Knight's Wordsight.
For an out of book booktest as requested above (I assume you mean, a booktest that doesn't stick with a book: Try The Billion Monkeys Book Test by Joshua Quinn in ParaLies.
And my personal favourite for booktests: Jon Thompson's Naked Book Test. Absolutely brilliant. I've done this over the phone and the internet as well. Any book, any page, any word, completely impromptu.
Please note that these are just some suggestions to look up for each category. I do not have most of these, I cannot vouch for most of these - but I've heard good things about all of them, and they're worth checking out.
