I am having trouble working around a problem with inheriting unit test cases. Suppose I have a base class Foo and several derived classes. Suppose I have a corresponding base test case and I would like to reuse that base test case with test cases for the derived classes. What I would like to do is this, in highly stylized form: class BaseFooTestCase { public: virtual Foo* create() = 0; void test_base() { Foo* foo = create(); // test foo ... } void add(test_suite* ts) { ts->add(BOOST_CLASS_TEST_CASE(&BaseFooTestCase::test_base, this); } }; class DerivedFooTestCase { public: virtual Foo* create() { return new Derived(); } void test_derived() { Foo* foo = create(); // test foo } void add(test_suite* ts) { BaseFooTestCase::add(ts); ts->add(BOOST_CLASS_TEST_CASE(&DerivedFooTestCase::test_derived, this); } }; Then, something like this: test_suite* init_unit_test_suite(int, char* []) { auto_ptr ts(new test_suite("test")); DerivedFooTestCase* tc = new DeriveFooTestCase(); tc->add(ts); return ts; } However, I can't get the add() methods in the test case classes worked out. The BOOST_CLASS_TEST_CASE macro seems to want a shared_ptr, and passing "this" to it does not seem to work. Could anyone please provide an example of how to do this? Every time I try to work this out, I end up with a mess --- static allocator methods, weak_ptr wrapped by shared_ptr, and other workarounds --- all of which works, but is really quite a lot of effort for what I want and is overly complex for me to recommend to my team as a solution. Any help appreciated. Thanks. Bill
