Hi Johan, The command line options I know of are: char * argv[] = { // defaults: "--build_info=yes", // no // "--catch_system_errors=no", // yes // "--detect_memory_leaks=0", // 1 // "--log_format=XML", // HRF "--log_level=messages", // all_errors // "--no_result_code=no", // yes "--output_format=XML", // HRF (overrides log_format & report_format) "--random=1", // 0 // "--report_format=XML", // HRF "--report_level=detailed", // confirm // "--show_progress=yes" }; // no To output to files, I use set_stream. I found it made things easier to have my own version of Boost.Test's "main" function, like this: // based on: "main" in <boost\test\impl\unit_test_main.ipp> int my_unit_test_entrypoint() { using namespace ::boost::unit_test; int ret = boost::exit_exception_failure; try { char * argv[] = { /*add cmdline options here*/ }; // see above int argc = sizeof( argv ) / sizeof( char * ); framework::init( argc, argv ); std::ofstream logStream( "c:\\log.xml" ); unit_test_log.set_stream( logStream ); framework::run(); std::ofstream reportStream( "c:\\report.xml" ); results_reporter::set_stream( reportStream ); results_reporter::make_report(); if ( runtime_config::no_result_code() ) { ret = boost::exit_success; } else { test_unit_id id = framework::master_test_suite().p_id; ret = results_collector.results( id ).result_code(); } } catch( std::logic_error const & ex ) { /*add error reporting here*/ } catch( ... ) { /*add error reporting here*/ } return ret; } Hope this helps! John Fearnside -----Original Message----- From: Johan Nilsson [mailto:r.johan.nilsson@gmail.com] Hi, I'm using the Boost.Test (unit test framework) from cvs, trying to get xml output redirected into files. The xml format itself is not a problem, but I can't find any options to get the output into files. Is this possible to do using either command-line arguments or environment variables? It's possible, but awkard, to use unit_test_log::set_stream, but I figured I'd check if there were any options before implementing that. / Johan
