[Boost-users] Unit testing Questions

I'm a newbie with boost and have some questions about unit testing- 1 - In looking for documentation, I see that most of the sample links on the boost.org site for unit testing examples are dead. Is there another place I can see them. 2 - Is there a good tutorial on all of the features of boost testing? It looks really good, but it seems to be really hard to follow. 3 - Is there a way to test for 1.#QNAN in a floating point value? This is part of my initialization sequence. "BOOST_CHECK_EQUAL" results a failure. Thanks in advance. Thomas Thorp Senior Software C++ Engineer Advanced Composite Software - Production
