如何在AutoDataAttribute子类中创建模拟类？

using AutoFixture;
using AutoFixture.Xunit2;
using Moq;
using Xunit;

public class MyAutoDataAttribute : AutoDataAttribute
{
    public MyAutoDataAttribute() : base(CreateFixture)
    {
    }

    private static IFixture CreateFixture()
    {
        var fixture = new Fixture();

        // 创建模拟对象
        var mockService = new Mock<IService>();

        // 配置模拟对象的行为
        mockService.Setup(s => s.DoSomething()).Returns("Mocked result");

        // 将模拟对象作为测试数据返回
        fixture.Inject(mockService.Object);

        return fixture;
    }
}

public interface IService
{
    string DoSomething();
}

public class MyTestClass
{
    [Theory]
    [MyAutoData]
    public void MyTestMethod(IService service)
    {
        // 使用模拟对象进行测试
        var result = service.DoSomething();

        // 断言测试结果
        Assert.Equal("Mocked result", result);
    }
}
