Getting started

Install

dotnet add package Tharga.Test.Toolkit

Tharga.Test.Toolkit targets .NET Standard 2.0, so it works in any test project on .NET Framework 4.6.1+, .NET Core 2.0+, or modern .NET (including .NET 8 / 9 / 10).

Namespace

Everything lives under Tharga.Test.Toolkit:

using Tharga.Test.Toolkit;

Assignment checks — minimal example

IsAssigned() walks the object graph and returns true only if every property and field holds a non-default value. Use it as a one-line assertion that a mapping / copy populated everything:

var customer = new Customer { Id = 7, Name = "Ada", Country = "SE" };
Assert.True(customer.IsAssigned());

If you need to know which members failed, call AssignmentIssues() instead — it returns one IAssignmentIssue per missing field:

foreach (var issue in customer.AssignmentIssues())
{
    Console.WriteLine($"{issue.ObjectName}: {issue.Message}");
}

See Assignment checks for the ignore-list, nested-object behaviour, and the TestAssignments method-roundtrip helper.

Dependency tests — minimal example

DependencyTestBase exposes the referenced assemblies of a target assembly, filtered to a configurable ignore list. Subclass it to write tests that pin which references are allowed:

public class ApiDependencyTests : DependencyTestBase
{
    public ApiDependencyTests()
        : base(typeof(MyApi.Startup).Assembly)
    {
    }

    [Fact]
    public void Api_does_not_reference_EntityFramework()
    {
        Assert.DoesNotContain(GetDependencies(), d => d.Name.StartsWith("EntityFramework"));
    }
}

See Dependency tests for the custom ignore-list overload and the standard ignored assemblies.
