Detailed Description
John Farrier
A Celero Test Fixture for array transforms.
This test fixture will build a experiment of powers of two. When executed, the selected experiment is used to create an array of the given size, then push random integers into the array. Each transform function will then modify the randomly generated array for timing.
This demo highlights how to use the ExperimentValues to build automatic test cases which can scale. These test cases should ideally be written to a file when executed. The resulting CSV file can be easily plotted in an application such as Microsoft Excel to show how various tests performed as their experiment scaled.

Allows a test fixture to supply values to use for experiments.
This is used to create multiple runs of the same experiment and varrying the data set size, for example. The second value of the pair is an optional override for the number of iterations to be used. If zero is specified, then the default number of iterations is used.
It is only guaranteed that the constructor is called prior to this function being called.
Reimplemented from celero::TestFixture.
The documentation for this class was generated from the following file:
