TedToolkit.Assertions.Logging

An extension for TedToolkit.Assertions that routes assertion failures through Microsoft.Extensions.Logging instead of (or in addition to) throwing exceptions.

Installation

dotnet add package TedToolkit.Assertions.Logging

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

Push a LoggerScope around the code whose assertion failures you want logged. The most ergonomic entry points are the Push / FastPush extension methods on ILogger:

using TedToolkit.Assertions;
using TedToolkit.Assertions.Logging;

// async-safe (flows across await boundaries)
using (logger.Push())
{
    name.Must().Not.BeNullOrEmpty();
    age.Should().BeGreaterThan(0);
    await DoWorkAsync();
}

// synchronous fast path (thread-local, ref struct — cannot cross await)
using (logger.FastPush())
{
    name.Must().Not.BeNullOrEmpty();
}

Severity → log level

Assertion Log level Throws?
Could Information no
Should Warning no
Must Error ArgumentException

Aggregating with AssertionScope

Failures inside an AssertionScope are collected and reported once on scope exit. The log level reflects the highest severity in the batch:

using (logger.Push())
using (new AssertionScope("validating order").Push())
{
    order.Name.Must().Not.BeNullOrEmpty();
    order.Amount.Must().BeGreaterThan(0);
    order.Discount.Should().BeInRange(0, 100);
}
// One log entry with all failures; throws ArgumentException because the batch
// contains MUST failures.

Behavior notes

  • The first reference to LoggerScope permanently replaces AssertionStrategy.ItemStrategy and AssertionStrategy.ScopeStrategy for the AppDomain. Don't combine this package with another strategy customization.
  • Outside a LoggerScope, Could / Should failures are silently dropped (no log, no throw). Must still throws an ArgumentException. Push a LoggerScope before running assertions whose failures you want surfaced.
