Boost.Test does support it. It's just require some extra leg work from you.

These rather belong to the advanced usage cases. These docs are only in plans.

This is not what expected to do. This is my own internal unit test.

Should not matter, but I just tested and global fixture is invoked too late.

You can look into the code. There are at least two implemented there.

Here an example that works fine:

#include <boost/test/unit_test.hpp>
#include <boost/test/parameterized_test.hpp>
using namespace boost::unit_test;

// STL
#include <vector>
#include <string>


// this free function is invoked with all parameters specified in a list
void check_string( std::string const& s )
    // reports 'error in "check_string": test s.substr( 0, 3 ) == "hdr" failed
[actual_value != hdr]'
    BOOST_CHECK_EQUAL( s.substr( 0, 3 ), "hdr" );


static struct Setup { Setup() {
 framework::master_test_suite().p_name.value =
    "Automatically registered param test case";

    // parameters have no requirements to stay alive beyond the next statement
    std::string const params[] = { "hdr1 ", "hdr2", "3 " };

     BOOST_PARAM_TEST_CASE( &check_string,
                            (std::string const*)params,
                            params+3 ) );
} } _s_setup;
