Can't you do something like this? Or is the unit test framework supposed 
to provide its own "root"/main module?

---
module unittestframework;

void runTests(string root_module = __MODULE__)()
{
    // start recursion from root_module
}
---

---
module appmain;
import unittestframework;

void main()
{
	runTests();
}
