Hi, While working on Boost.Test documentation update I've realized that there is no substantial reason anymore to keep this component around. The Unit Test Framework work just as well and does not require any more effort. Here is an example: Using the Test Execution Monitor: ---------------------------------- #include <boost/test/test_exec_monitor.cpp> int test_main( int, char* [] ) { /// your testing is here return 0; } Using the Unit Test Framework: ---------------------------------- #define BOOST_TEST_MAIN #include <boost/test/unit _test.cpp> BOOST_AUTO_TEST_CASE( my_test ) { /// your testing is here } There are monor preferences for either solution (test_main look like main, but require return statement and argument specifications). But from usability standpoint they are similar. I know that many Boost developers are using this component. So I would like to hear community opinion. If nobody speak up I am planning to depricate this component (first from documentation in 1.34, an from source code in 1.36) Regards, Gennadiy
