Hello : I am using boost::test to provide testing in multiple modules (dlls on win32). A single exe is used to call each of the test facilities in each module. In theory the above sounds ideal, especially as each individual unit test within a module is registered via an abstract factory. In practice, however, I am unable to link the individual modules properly as each one seems to require the function init_unit_test_suite() to be defined. This is mentioned in the FAQ but I have not yet found documentation or examples documenting boost::test spanning multiple modules. I would think that one instance of init_unit_test_suite() would be necessary within the controlling exe, and that each module (dll) would link statically against the boost::test library. Linking against this library, however, causes the problems described above. If anyone has suggestions or an example I would be grateful. Many thanks; sga
