Parameterized Performance Test Example by koszeggy

using System;
using KGySoft.CoreLibraries;
using KGySoft.Diagnostics;

// This example demonstrates how to derive the PerformanceTestBase class to create parameterized performance tests.
// Now we will use a Random instance, which is reset before every case
public class RandomizedPerformanceTest<T> : PerformanceTestBase<Func<Random, T>, T>
{
    private Random random;

    // a fix seed can be specified when initializing the test
    public int Seed { get; set; }

    protected override T Invoke(Func<Random, T> del) { return del.Invoke(random); }

    // resetting the random instance with the specified seed before executing each case
    protected override void OnBeforeCase() { random = new Random(Seed); }
}

public class Program
{
	public static void Main()
	{
		new RandomizedPerformanceTest<string>
			{
				Seed = 0, // our new property
				Iterations = 1_000_000,
			}
			.AddCase(rnd => rnd.NextEnum<ConsoleColor>().ToString(), "Enum.ToString")
			.AddCase(rnd => Enum<ConsoleColor>.ToString(rnd.NextEnum<ConsoleColor>()), "Enum<TEnum>.ToString")
			.DoTest()
			.DumpResults(Console.Out);
