I am having trouble working around a problem with inheriting unit
test cases. ...
I have found an answer:

#include <iostream>
#include <boost/test/unit_test.hpp>

using namespace boost::unit_test;
using namespace std;

struct Foo { virtual void foo(string) = 0; };
struct Bar : public Foo { void foo(string n) { cout << "in " << n << "\n"; }};

class CommonTest {
public:
    void test_base() {
        auto_ptr<Foo> foo(create());
        foo->foo("CommonTest");
    }
    virtual Foo* create() = 0;
};

class ConcreteTest : public CommonTest {
public:
    void test_concrete() {
        auto_ptr<Foo> foo(create());
        foo->foo("ConcreteTest");
    }
    virtual Foo* create() { return new Bar(); }
};

test_suite* init_unit_test_suite(int, char* []) {
    auto_ptr<test_suite> suite(new test_suite());

    boost::shared_ptr<CommonTest> common_test(new ConcreteTest());
    suite->add(BOOST_CLASS_TEST_CASE(&CommonTest::test_base, common_test));

    boost::shared_ptr<ConcreteTest> concrete_test(new ConcreteTest());
    suite->add(BOOST_CLASS_TEST_CASE(&ConcreteTest::test_concrete,
                                     concrete_test));

    return suite.release();
}
