Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Log level configuration

If you need to enforce specific log level from within your test module use the following interface:

boost::unit_test::unit_test_log.set_threshold_level( boost::unit_test::log_level );

or for a specific logger:

boost::unit_test::unit_test_log.set_threshold_level( boost::unit_test::output_format, boost::unit_test::log_level );

	Tip
	See `boost::unit_test::unit_test_log_t::set_threshold_level` and `boost::unit_test::output_format` for more details

In regular circumstances you shouldn't use this interface, since you not only override default log level, but also the one supplied at test execution time. Prefer to use runtime parameters --log_level or --logger for log level selection.

Example: Compile-time log level configuration

Code

#define BOOST_TEST_MODULE example
#include <boost/test/included/unit_test.hpp>
#include <boost/test/unit_test_parameters.hpp>
using namespace boost::unit_test;

BOOST_AUTO_TEST_CASE( test_case0 )
{
  if( runtime_config::get<log_level>( runtime_config::btrt_log_level ) < log_warnings )
    unit_test_log.set_threshold_level( log_warnings );

  BOOST_WARN( sizeof(int) > 4 );
}

Output
> example Running 1 test case... test.cpp(13): warning in "test_case0": condition sizeof(int) > 4 is not satisfied *** No errors detected
