I have not had a chance to try Boost.Test. It's on our list of things to
try, but we have a time and code investment in CppUnit already.

I need to look at this a little more. setUp and tearDown are called
before and after each test. I dont know how this could be simulated with
constructors or member variables.

Conceptually a fixture establishes a known good test environment for the
test independent of all previous tests. That is each unit test should be
seperate and independent. setUp and tearDown in Fixtures was designed to
establish this environment.

I would need to study Boost.Test more to understand how this might be
made possible.

Equivalent to setUp and tearDown.
