I think this change is overall ok but I'm not too fond of using operator().
I'd prefer if you kept the original variant of calling a static method 
on class Runner instead.

Something like:
  63 class SmallResourceHashtableTest : public CommonResourceHashtableTest {
   64  protected:
   65
   66   template<
   67   unsigned (*HASH) (K const&) = primitive_hash<K>,
   68   bool (*EQUALS)(K const&, K const&) = primitive_equals<K>,
   69   unsigned SIZE = 256,
   70   ResourceObj::allocation_type ALLOC_TYPE = ResourceObj::RESOURCE_AREA

   71   >
   72   class Runner : public AllStatic {


   73    public:
   74
   75     static void test(V step) {
...

The class is only there to allow template parameters with default values 
anyway.
