How to measure a method multiple times with different parameter values

[David Karr]

I want to benchmark the performance of a method that takes a parameter, a
list of objects to be more specific.  I can easily write a benchmark that
creates a static list and write a benchmark that takes the body of the
original method and references the static list.

Instead of benchmarking a void method, I'd really like to benchmark the
method that takes the list parameter, keeping the signature, and having it
return the value.

I would also like to run multiple benchmarks of the same method, but with
different values sent to the method, mostly to test it with different list
lengths.
