FluentFuzzer 0.0.4

FluentFuzzer Documentation

If you need fuzzing for your integration tests or unit tests, you can use FluentFuzzer and any unit tests framework, which you have used already.

How to use

1. Simple example, which used NUnit framework. Parameter timeInSec set duration method execution:

public class ConstructClass
{
	public string Name { get; set; }

	public List<string> NameChildren { get; set; }

	public int Age { get; set; }
}

[TestFixture]
public class FuzzerRunnerConstructTests
{
	[Test]
	public async Task FuzzerTestConstructObject()
	{
		await Fuzzer.Instance.RunAsync<ConstructClass>(async construction =>
		{
			await Task.Delay(100);
			if (construction is not null)
				Console.WriteLine(construction.Name + " " + construction.NameChildren?.Count + " " + construction.Age);
		},
		timeInSec: 300);
	}
}

2. There is parallel execution. Set 2 threads:

await Fuzzer.Instance
	.MakeParallelExecution(2)
	.RunAsync<string>(async text =>
	{
		await Task.Delay(100);
		if (DateTime.TryParse(text, out var dt1))
		{
			var s = dt1.ToString("O");
			var dt2 = DateTime.Parse(s, null, DateTimeStyles.RoundtripKind);

			if (dt1 != dt2)
				throw new Exception();
		}
	});

3. You can write result with exeption to folder.

await Fuzzer.Instance
	.MakeParallelExecution(2)
	.WriteResultToFolder("C:/Result/MyFuzzing")
	.RunAsync<string>(async text =>
	{
		await Task.Delay(100);
		if (text.Contains("1"))
			throw new Exception("Tests exception");
	});
