我想告诉Machine.Fakes框架在创建主题时使用特定值作为构造函数参数

测试对象具有以下构造函数

    /// <summary>
    /// Initializes a new instance of the <see cref="CsvFileRepository{TModel}"/> class.
    /// </summary>
    /// <param name="fileService">The file service.</param>
    /// <param name="repositorySettings">The repository settings.</param>
    /// <param name="mappingFunction">The mapping function. The mapping function takes in a line from the CSV file and returns the model for said line.</param>
    public CsvFileRepository(IFileService fileService, IRepositorySettings repositorySettings, Func<string, TModel> mappingFunction)
    {
        this.FileService = fileService;
        this.RepositorySettings = repositorySettings;
        this.MappingFunction = mappingFunction;
    }

我已经创建了一个测试存根,如下所示:

public class when_i_pass_a_csv_file_the_results_are_mapped_to_model_objects : WithSubject<CsvFileRepository<StandardOffer>>
{
    Establish context = () => …

我用Machine.Fakes打了一个僵局.我无法弄清楚如何仅out使用Machine.Fakes设备模拟参数.由于RhinoMocks 中存在错误,我将mfakes适配器切换为FakeItEasy.据我所知,任何适配器都应该是可互换的.

问题是这导致"out"测试失败,看起来像这样的东西不再编译,因为Arg是Rhino.Mocks.

The<IMembershipService>()
    .WhenToldTo(x => x.CreateUser(Param<string>.IsAnything,
        Param<bool>.IsAnything,
        Param<object>.IsAnything, 
        out Arg<MembershipCreateStatus>
            .Out(MembershipCreateStatus.UserRejected)
            .Dummy))
    .Return(user);

我尝试使用"虚拟"局部变量,设置为原始Arg<T>参数设置的相同值,但这导致我的测试失败 - 好像值没有被传递! Arg<T>真的有解决方案,但我不能再使用它了,因为它是Rhino.Mocks的一部分.

假设我的上下文配置类似于:

Establish context = () =>
    {
        ...

        IFileProcesser processer = new FileProcesser();

        The<IFileProcesser>()
            .WhenToldTo(x => x.Read(Param<Stream>.IsAnything))
            .Return<Stream>(processer.Read);

        ...
    };

有没有更好的方法告诉M​​achine.Fakes不要伪造IFileProcesser并使用FileProcesser的实现？
