Automate the testing of all your object-to-object mappers with one line of unit test code. <p align="center"> <img src="https://avatars.githubusercontent.com/u/103217522?s=150&v=4" alt="XMapper logo"/> </p>

Available via NuGet.

For more information about creating and using a mapper, see XMapper.


  1. Assign your mappers to static fields or static properties:
using XMapper;

namespace DummyAssembly1;

public class Class1 // An example of an incomplete setup: DummyB.XStringB has no match.
    public static readonly XMapper<DummyA, DummyB> MapperField =
        new XMapper<DummyA, DummyB>(PropertyList.Target)
        .IgnoreTargetProperty(x => x.XStringA);

public class DummyA
    public int XInt { get; set; } = 1;

public class DummyB
    public int XInt { get; set; } = 2;
    public string XStringA { get; set; } = "A";
    public string XStringB { get; set; } = "B";
  1. Test all mappers via a single method call inside a unit test:
using XMapper.Testing;
using Xunit;
using Xunit.Abstractions;

public class MyXMapperTests
    private readonly ITestOutputHelper _testOutputHelper;
    public MyXMapperTests(ITestOutputHelper testOutputHelper)
        _testOutputHelper = testOutputHelper;

    public void AllAreValid()
        new XMapperValidator(_testOutputHelper.WriteLine).AllAreValidInAssembly("DummyAssembly1", TestCases.All);

In case the unit test passes, the Standard Output in Visual Studio's Test Explorer will show something like:

Start collecting XMapper instance storage locations (static fields/properties).
Found 2 XMapper instance storage locations to test.

Finished validating all XMapper instances.

All assert options

AllAreValidInAssembly("Project1", TestCases.All);

AllAreValidInAssemblies(new [] { "MyProject1", "MyProject2" }, TestCases.All);

AllAreValidInAssembly(Assembly.Load("AnotherAssembly"), TestCases.All); 

AllAreValidInAssemblies(new [] { Assembly.Load("MyAssembly1"), Assembly.Load("MyAssembly2") }, TestCases.All);

// or only validate specific mappers:
IsValid(mapper, TestCases.All);

// or specify only specific test cases from the TestCases flags enum:
AllAreValidInAssembly("Project1", TestCases.NotNullDefaults | TestCases.TargetNullDefaults);

Hovering over methods and TestCases enum values in your editor will provide guiding documentation.
