Hi, I want to use boost test in a particular way, I'm not sure if it's even possible, suggestions/advice are greatly appreciated. I have a shared library consisting of many classes. I would like to write my BOOST_AUTO_TEST_CASE at the end of the implementation of each class so as to encourage always writing tests. So this is what I've done, included in the implementation file of each class, and wrote the test cases for each class at the end of the .cpp file for that class. In one of the .cpp files, I've stuck the following at the top to produce a canned 'main': #ifdef TEST #define BOOST_TEST_MAIN #include #endif and compiled this particular file twice, so now I have a library without a main, and an executable with a main. The self-contained executable runs the tests perfectly as intended. The problem is that now the library is dependent on boost::test, any program that links against this library now needs to also link against the boost::test library (otherwise I get linker errors) which is _highly_ undesirable. It is perfectly fine however, if the tests get included/instantiated in the library but never get called, that's a perfectly valid solution. I also don't want to wrap the inclusion/code for the tests in ifdefs, since this will mean that the code (which is a lot) will have to be compiled twice and this process gets messy and tedious. Is there a way to accomplish this? Regards, Ahmed
