Array with test definitions. Each entry needs a name string and an operation function. The operation function gets a single numeric
argument which is incremented during each test run. The function should use this argument to generate a dynamic result which it must return
to prevent the JS engine from discarding meaningless operations or optimizing static operations which would make the benchmark useless.
