RhinoMocks模拟RestSharp客户端

Question

我在使用RhinoMocks和Nunit从RestSharp创建RestClient实现的简单模拟时遇到麻烦。

我正在将RestClient和一些配置值注入到sut中。

  public class MyRestApiAbstraction : IRestApi
  {
        private const string BaseUrl = "basepath";

        private readonly IRestClient _restClient;

        public MyRestApiAbstraction (IOptions<MyConfig> configuration, IRestClient restClient)
        {
            var conf = configuration;
            _restClient = restClient;
            _restClient.Authenticator =
                new HttpBasicAuthenticator(conf.Value.Username,
                    conf.Value.Password);
            _restClient.BaseUrl = new Uri(conf.Value.Hostname + BaseUrl, UriKind.Absolute);
        }

        public IRestResponse<T> Execute<T>(RestRequest request) where T : new()
        {
            return IsSuccessful(_restClient.Execute<T>(request));
        }

        private static IRestResponse<T> IsSuccessful<T>(IRestResponse<T> response)
        {
            if (!response.StatusCode.Equals(HttpStatusCode.OK))
                throw new CustomException1(response.StatusCode);

            if (response.ResponseStatus == ResponseStatus.TimedOut || response.ResponseStatus == ResponseStatus.Aborted)
                throw new CustomException3("test");

            return response;
        }
    }

在startup.cs中，我像这样解决ÌRestClient依赖项：

services.AddScoped<IRestClient>(provider => new RestClient());

然后在测试中，我将依赖关系创建为模拟对象并创建sut对象。

   [Test]
   public void Execute_Successful()
   {
       //Arrange
       var request = new RestRequest();
       var response = new RestResponse<Wrapper<Model>>
           {StatusCode = HttpStatusCode.OK, ResponseStatus = ResponseStatus.Completed};
       var restClient = MockRepository.GenerateMock<RestClient>();
       restClient.Stub(client =>
          client.Execute<Wrapper<Model>>(Arg<RestRequest>.Is.Anything))
          .Return(response);
       var myRestApiAbstraction = new MyRestApiAbstraction (Options.Create(_config), restClient);

       //Act 
       sapRestApi.Execute<SapResponseWrapper<OfferOfCompromiseProtocol>>(request);

       //Assert
   }

当我尝试运行测试时，出现此异常：

SapVangProcessing.UnitTests.SapRestApiTests.Execute_Successful

System.MissingMethodException : Can't find a constructor with matching arguments

如果我查看RestClient的来源，就会发现它具有默认的构造函数。

我在这里做什么错了？
