Comment (by rogeeff):

 What you are looking for is not a timed test case, but specialized
 performance tester.

 something like

 template<Profiler, Func>
 Profiler::interval_type
 time_invocation( Func f );

 additional parameters may include:
 unsigned                num_times_to_repeat
 Profiler::interval_type total_test_time
 unsigned                num_of attempts_to_ignore;
 double                  bottom_percent_to_ignore;
 double                  top_percent_to_ignore;
 unsigned                minimal_number_of_attempts;

 I would use named parameters interface to specify these.

 To accomodatelast need I would use something like:

 template<Profiler, Func, ParamIter, ExpectedComplexityFunc>
 Profiler::interval_type
 test_complexity( Func f, ParamIter first_param, ParamIter last_parm,
 ExpectedComplexityFunc ec );

 this should test that performance numbers match predicate when collected
 over set of parameters
