MonadicTypes.NET.Testing

Framework-neutral assertions for MonadicTypes.NET tests. The package has no dependency on xUnit, NUnit, MSTest, or any other test framework; it provides a small assertion exception that each test framework can report normally.

Install

dotnet add package MonadicTypes.NET.Testing --prerelease

Quick Start

using MonadicTypes.Testing;

Result<User, LookupError> result = LoadUser();
User user = result.ShouldBeOk("load user").ValueOrFail();
LookupError error = result.ShouldBeError().ErrorOrFail();
Option<User> optional = FindUser();
User present = optional.ShouldBeSome().ValueOrFail();

ShouldBeOk, ShouldBeError, ShouldBeSome, and ShouldBeNone return the unchanged value so assertions can be composed with ordinary test-framework assertions. ValueOrFail and ErrorOrFail throw MonadicAssertionException with the actual case in the message. The helpers use only public Result/Option APIs and do not affect production consumers.
