Masterly.NonEmptyList.Testing

Test support for Masterly.NonEmptyList: CsCheck generators, an AutoFixture customization and the published law suite.

Installation

dotnet add package Masterly.NonEmptyList.Testing

CsCheck generators

Every generator yields at least one element, so properties never need an empty guard.

using CsCheck;
using Masterly.NonEmptyList.Testing;

NonEmptyGen.List(Gen.Int).Sample(xs => xs.Map(x => x) == xs);
NonEmptyGen.Sorted(Gen.Int).Sample(xs => xs.Head <= xs.Last);
NonEmptyGen.Constrained<int, AtLeast<Two>>(Gen.Int, minCount: 2).Sample(xs => xs.Second() == xs[1]);
NonEmptyGen.String().Sample(s => !string.IsNullOrWhiteSpace(s.Value));

Available: List, Immutable, Set, Dictionary, Constrained, Sorted, Distinct, String, EventStream, Zipper, Tree, Validation.

AutoFixture

IFixture fixture = new Fixture().Customize(new NonEmptyCustomization());

Order order = fixture.Create<Order>();   // NonEmptyList, NonEmptySet, NonEmptyString, ConstrainedList properties all populated

Generated [NonEmptyCollection] classes resolve too. Constrained types are shrunk until their constraint holds.

Laws

NonEmptyListLaws exposes the functor, monad, fold and structural laws as boolean functions, plus CheckAll(xs) which returns the names of any laws that fail. Use them to verify your own extension methods or forks:

NonEmptyGen.List(Gen.Int).Sample(xs => NonEmptyListLaws.CheckAll(xs).Count == 0);
NonEmptyGen.List(Gen.Int).Sample(xs => NonEmptyListLaws.MapComposition(xs, x => x + 1, x => x * 2));
