Trellis.Testing

NuGet Package

FluentAssertions extensions and test doubles that make Result and Maybe tests read like intent instead of plumbing.

Installation

dotnet add package Trellis.Testing

Quick Example

using FluentAssertions;
using Trellis;
using Trellis.Testing;

var result = Result.Ok(42);
var maybe = Maybe.From("Ada");

result.Should().BeSuccess().Which.Should().Be(42);
maybe.Should().HaveValue().Which.Should().Be("Ada");

Key Features

  • Result assertions — BeSuccess(), BeFailure(), BeFailureOfType<T>(), async variants
  • Maybe assertions — HaveValue(), BeNone(), HaveValueEqualTo()
  • Error/Error.InvalidInput assertions — HaveCode(), HaveFieldError()
  • Unwrap helpers — Extract values in test code without analyzer warnings
  • FakeRepository — In-memory aggregate store with domain event tracking
  • TestActorProvider — Mutable IActorProvider for authorization tests

For ASP.NET Core integration test helpers (WebApplicationFactory, DI replacement), see Trellis.Testing.AspNetCore.
