t.d:
     module t;
     template t(T) {
         static if(is(T == int))
             alias int t;
         else static if(is(T == short))
             alias short t;
     }
     unittest {
         t!int a = 10;
         assert(a == 10);
     }
     void main() {}

$ dmd -unittest -cov -run t

t.lst:
        |    module t;
        |    template t(T) {
        |        static if(is(T == int))
        |            alias int t;
        |        else static if(is(T == short))
        |            alias short t;
        |    }
        |    unittest {
       1|        t!int a = 10;
       1|        assert(a == 10);
        |    }
        |    void main() {}
t.d is 100% covered

A code coverage tells how many time a line of code is run at 
run-time. But your template contains no code that is run at 
run-time. So you are looking for a different kind of counter.

Makes sense. Would be nice to easily see that the templates are 
being tested more properly though.

Then add an enhancement request in bugzilla. Maybe there is a way 
to implement it.

I remember someone asking for a compiler switch that lists all 
the implemented templates...
