TedToolkit.Assertions.FluentValidation

An extension for TedToolkit.Assertions that integrates with FluentValidation, allowing you to assert that an object passes a FluentValidation validator.

Installation

dotnet add package TedToolkit.Assertions.FluentValidation

This package requires TedToolkit.Assertions (installed automatically as a dependency).

Supported Frameworks

.NET 6 / 7 / 8 / 9 / 10, .NET Framework 4.7.2 / 4.8, .NET Standard 2.0 / 2.1

Usage

Use the BeValidBy assertion to validate an object against a FluentValidation validator:

using TedToolkit.Assertions;
using TedToolkit.Assertions.FluentValidation;

// Define a validator
public class OrderValidator : AbstractValidator<Order>
{
    public OrderValidator()
    {
        RuleFor(x => x.Name).NotEmpty();
        RuleFor(x => x.Amount).GreaterThan(0);
    }
}

// Assert using the validator
var order = new Order { Name = "Widget", Amount = 5 };
order.Must().BeValidBy(new OrderValidator());

You can also pass a validation strategy to control which rules are evaluated:

order.Must().BeValidBy(new OrderValidator(), strategy =>
    strategy.IncludeRuleSets("QuickCheck"));

When the assertion fails, the error message includes all validation errors returned by FluentValidation.
