OK so it takes a little boilerplate.

unitests
{
   static const name = "Foo";

   if(!RunTestByName(name)) return;
   try
   {

   /// tests

   }
   catch(Excption e)
   {
      ProcessUnittestError(name,e);
   }
}

Or to be even cleaner

unittest
{
   RunTests!(Foo, Bar, Baz)();
}

void Foo() { /* tests */ }
void Bar() { /* tests */ }
void Baz() { /* tests */ }
