为什么在编写Xunit测试用例错误聊天机器人.net核心时出错

Question

这是我得到的错误：

Castle.DynamicProxy.InvalidProxyConstructorArgumentsException：无法实例化以下类的代理：SampleAssignment.LeaveApplicationBookingRecognizer。 找不到与给定参数匹配的构造函数： Castle.Proxies.IConfigurationProxy

请帮助我提供一些合适的解决方案。

    public class LeaveApplicationBookingRecognizer : IRecognizer
    {
        private readonly LuisRecognizer _recognizer;
        private readonly IConfiguration _configuration;

        public LeaveApplicationBookingRecognizer(IConfiguration configuration)
        {
            _configuration = configuration;
            var luisIsConfigured = !string.IsNullOrEmpty(configuration["LuisAppId"]) && 
            !string.IsNullOrEmpty(configuration["LuisAPIKey"]) && 
            !string.IsNullOrEmpty(configuration["LuisAPIHostName"]);
            if (luisIsConfigured)
            {
                var luisApplication = new LuisApplication(
                    configuration["LuisAppId"],
                    configuration["LuisAPIKey"],
                    "https://" + configuration["LuisAPIHostName"]);
                // Set the recognizer options depending on which endpoint version you want to use.

                var recognizerOptions = new LuisRecognizerOptionsV3(luisApplication)
                {
                    PredictionOptions = new Microsoft.Bot.Builder.AI.LuisV3.LuisPredictionOptions
                    {
                        IncludeInstanceData = true,
                    }
                };

                _recognizer = new LuisRecognizer(recognizerOptions);
            }
        }

        // Returns true if luis is configured in the appsettings.json and initialized.
        public virtual bool IsConfigured => _recognizer != null;

        public virtual async Task<RecognizerResult> RecognizeAsync(ITurnContext turnContext, CancellationToken cancellationToken)
            => await _recognizer.RecognizeAsync(turnContext, cancellationToken);

            where T : IRecognizerConvert, new()
            => await _recognizer.RecognizeAsync<T>(turnContext, cancellationToken);
    }
