LightMoq

Extensions for LightMock.Generator to make it more like Moq.

Why?

I had written a lot of tests for C# Godot projects using Moq, but Moq relies on dynamic code generation at runtime to create the proxies that power mocks. That currently doesn't play nicely with collectible assemblies inside Godot, and I think the future of mocking in C# will probably center around source generators, anyways.

I didn't want to update hundreds of tests, and I like Moq's syntax. So I created a few extensions for LightMock to make it behave more like Moq.

Usage

Just make a mock (exactly how you would with LightMoq.Generator) and call Setup on it to stub methods. You can also use VerifyAll, which will verify all stubbed methods are called at least once, in any order.

namespace LightMoqTests;

using System;
using LightMock.Generator;
using LightMoq;
using Shouldly;
using Xunit;

internal interface IMyObject {
  void DoSomething();
  string SaySomething();
}

public class LightMoqTest {
  [Fact]
  public void TestObjectIsUsable() {
    var myObject = new Mock<IMyObject>();

    var speech = "Hello World!";

    myObject.Setup(obj => obj.DoSomething());
    myObject.Setup(obj => obj.SaySomething()).Returns(speech);

    myObject.Object.DoSomething();
    myObject.Object.SaySomething().ShouldBe(speech);

    // Make sure all stubbed methods were called at least once, in any order.
    myObject.VerifyAll();
  }
}
