Boost C++ Libraries

It is now possible to combine tolerance indication, user message and collection comparison modifier in a single BOOST_TEST expression

std::vector<double> v1 = f();
std::vector<double> v2{1.1, 1.19};
BOOST_TEST(v1 == v2, boost::test_tools::tolerance( 1e-3 ) << "comparison to ground truth failed" << boost::test_tools::per_element());

It is now possible to use floating point comparison without being required to cast both operands to floating point types. Now Boost.Test uses floating point comparisons for expressions such as

BOOST_TEST(3.0001 == 3);

See this section for more information.

Boost.Test minimal.hpp is now showing a deprecation warning. minimal.hpp has been deprecated for a long time already, and will be removed in the near future. Please switch to eg. the header only variable of Boost.Test. Tests using minimal.hpp can readily be converted to the header variant. For instance, the following code:

#include <boost/test/minimal.hpp>
int test_main( int, char *[] )
{
  ...
}

may be rewritten as:

#include <boost/test/included/unit_test.hpp>
BOOST_AUTO_TEST_CASE(test_main)
{
  ...
}
