> Most require you to build libraries. This can be a turn off to anyone who wants to get up and running quickly - especially if you just want to try something out. This is especially true of exploratory TDD coding.

This is absolutely true, and especially painful/noticeable if you target multiple platforms. To work around this problem, I've started using the stand-alone version of the Boost Unit Test framework:

    #include <boost/test/included/unit_test.hpp>

The problem with including that, like many other Boost header-only libraries, is that they wreck havoc on compile time :/.
