That's neat. How can I specify the hierarchy of different suites? Say,
I have one master suite and would like to create a hierarchical tree
structures of suites, with tests being the leaves:

    0:        master
              /  \
    1:      s1   s2
            /     \
    2:   t_1..n   s3
                   \
    3:            t_1..n

I assume I cannot switch between automatic and manual registration
within one compilation unit. How could I achieve such a structure then?

Here is the example again. First, the master test suite (test1.cc):

    #define BOOST_TEST_DYN_LINK
    #include <boost/test/unit_test.hpp>

    void test() 
    { 
        BOOST_CHECK_EQUAL(true, false); 
        BOOST_REQUIRE_EQUAL(1, 1); 
    }

    bool init_unit_test()
    {
        boost::unit_test::test_suite* ts = BOOST_TEST_SUITE("test suite");
        ts->add(BOOST_TEST_CASE(&test));
        
        boost::unit_test::framework::master_test_suite().add(ts);

        return true;
    }

    int main(int argc, char* argv[]) 
    { 
        return ::boost::unit_test::unit_test_main(&init_unit_test, argc, argv); 
    } 

Then, I would like to add child suite automatically (test2.cc):

    #define BOOST_TEST_MODULE foo test suite
    #include <boost/test/unit_test.hpp>

    BOOST_AUTO_TEST_SUITE(foo_suite)

    BOOST_AUTO_TEST_CASE(foo)
    {
        BOOST_REQUIRE_EQUAL(42, 43);
    }   

    BOOST_AUTO_TEST_SUITE_END()

When I compile them via

    g++ test{1,2}.cc -lboost_unit_test_framework-mt

the output looks like this:

    Running 2 test cases...
    test2.cc:8: fatal error in "foo": critical check 42 == 43 failed [42 != 43]
    test1.cc:6: error in "test": check true == false failed [true != false]

    *** 2 failures detected in test suite "Master Test Suite"

This looks to me that test foo is part of the Master Test Suite, or am I
mistaken?
