hi, Essentially what I'm trying to do(the code is attached below) , is pass a base class member pointer (member function should automatically be visible in the derived class) , to the BOOST framework. However, since the member function is statically not visible in the derived class, a compile time error is generated . I'm *thinking* that some kind of casting operation is required but not very sure how! could anybody enlighten me as to how to get the code snippet below running? Thanks! CODE: #include <iostream.h> /*-------------------- BOOST FRAMEWORK --------------------- */ #include <test/included/unit_test_framework.hpp> using boost::unit_test_framework::test_suite; class baseTrailTest{ public: baseTrailTest(){}; ~baseTrailTest(){}; protected : void trail(){ cout << " trail!!!! " << endl; } }; class TrailTest: public baseTrailTest{ }; struct trail_test_suite : public test_suite { trail_test_suite() : test_suite("trail_test_suite") { // add member function test cases to a test suite boost::shared_ptr<TrailTest> instance(new TrailTest); add( BOOST_CLASS_TEST_CASE( &TrailTest::trail ,instance ), 0 ); } }; test_suite* init_unit_test_suite( int argc, char * argv[] ) { std::auto_ptr<test_suite> test( BOOST_TEST_SUITE( "example" ) ); /*if( argc < 2 ) return (test_suite*)0;*/ test->add( new trail_test_suite); return test.release(); }
