"The target to be tested is a C++ application, so  Python tools like
wsgi_intercept, twill, mechanize do not apply."

Which doesn't apply (correct me if I am wrong)  to a WSGI application
wrapped
around WebTest.

I just don't see how a C++ app would not be able to call it so he can
record

For example, when we test external API's that do not have a sandbox and we
need to make HTTP calls that return certain responses, we create something
similar to a WSGI app (in some cases we use Bottle) that has WebTest around
it, calls and responses are captured no matter where you are starting the
call from.

But then again, I might be wrong applying those solutions to Alex's problem
:)
