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

This is an older version of Boost and was released in 2024. The current version is 1.89.0.

Predefined log format selection

Predefined log format selection

The select at compile time the log format from the list of the formats supplied by the Unit Test Framework

boost::unit_test::unit_test_log.set_format( boost::unit_test::output_format );

or for adding a format:

boost::unit_test::unit_test_log.add_format( boost::unit_test::output_format );

	Caution
	`boost::unit_test::unit_test_log_t::set_format` above disables all formatters but the one provided as argument.

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

In regular circumstances you shouldn't use this interface. Prefer to use runtime parameters --log_format or --logger for predefined log format selection.

Example: Compile-time log format selection

Code

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

struct MyConfig {
  MyConfig() {
    unit_test_log.set_format( OF_XML );
  }
  ~MyConfig() {}
};

BOOST_TEST_GLOBAL_CONFIGURATION( MyConfig );

BOOST_AUTO_TEST_CASE( test_case0 ) {
  BOOST_TEST( false );
}

Output
> example --report_level=no <TestLog><Error file="test.cpp" line="23">check false failed</Error></TestLog>
