Because the new-style tests are intrustive, the exception that CppUnit throws on assertion failures is caught and processed with the application logic, which is far from ideal, because it's very difficult to find the cause of failure. What we'd like is a way to control what happens when an test assertion fails, such that we can properly log/print the failure, and even break in the debugger. The new macros allow us to control the behavior at compile-time and have added flexibility. For now, they log an assertion failure before invoking the CPPUNIT macro, and support a compile-time directive to assert, which is useful for breaking in the debugger.
