Fuzzer

Helping hand in testing.

Description

Fuzzer is a simple cases generator for unit tests. It brute-forces trough all possible combinations of provided values. It works with frequent values like 0 or 1 but can also do fuzzing with NaN and random strings that are megabytes in size.

Usage

Scenario scenario = new Scenario()
  .NonRandom()
  .Random(amount: 10)
  .RandomString(amount: 10, encoding: Encoding.UTF8)
  .RandomDateTime(amount: 10, kind: DateTimeKind.Utc)
  .Except(1UL)
  .Except(default(DateTime))
  .Except(default(Guid));

IEnumerable<object[]> results = new CasesGenerator<float, string, DateTime, Guid>(scenario);

with NUnit

like in SampleFixture.cs

    [TestFixture]
    public class SampleFixture
    {
        [Test]
        [TestCaseSource("SampleTestGenerator")]
        public void SampleTest(string name, double lattitude, double longitude, DateTime when)
        {
            // Your assertions go here
            Assert.True(true);
        }

        public static IEnumerable<TestCaseData> SampleTestGenerator()
        {
            Scenario scenario = new Scenario()
                .NonRandom()
                .Random(amount: 10);

            return new CasesGenerator<string, double, double, DateTime>(scenario)
                .Select(c => new TestCaseData(c));
        }
    }
