I have some internal (non-exported) classes in a DLL that I want to test. I'm trying to do this by exporting a testInternals() function that my tester application will add to it's test suite.

The problem I'm having is that to use any of the BOOST_CHECK_??? etc macros I have to include the file. This causes undefined symbol linker errors.

Is there a way to do what I want to do?

This scenario is not supported by Boost.Test 1.33.1. But it is supported by current CVS version. Moreover - there is new tool called boost_test_runner that you could use to perform the testing: boost_test_runner -test [-init ] Gennadiy
