Alexa 亮度自动测试问题

Question

我正在为 Alexa 开发一项智能家居技能，其中涉及控制具有各种功能的灯，例如亮度、色温 (CT) 等。我已经成功解决了所有其他问题，包括 CT、颜色和开/关功能。然而，我在通过与亮度功能特别相关的自动化测试时遇到了困难。

我的问题是运行自动化测试时的亮度问题，我收到亮度错误，详细信息如下；

场景一： 假设请求之前的初始状态是亮度设置为 75。

在第一个场景中，我保留了“SetBrightness”命令将其设置为 0 之前的亮度值，这也可以作为关闭灯的信号。

要求：

{
   "directive":{
      "header":{
         "namespace":"Alexa.BrightnessController",
         "name":"SetBrightness",
         "messageId":"fed54fb1-a40e-42c5-819d-53894fb19fd8",
         "correlationToken":"ctooken",
         "payloadVersion":"3",
         "endpoint":{
            "scope":{
               "type":"BearerToken",
               "token":"token",
               "endpointId":"b38d964c-0b55-4b9a-8c0c-c537721bd2e5",
               "cookie":{},
               "payload":{
                  "brightness":0
               }
            }
         }
      }
   }
}

         "name":"Response",
         "messageId":"fed54fb1-a40e-42c5-819d-53894fb19fd8-R",
         "correlationToken":"ctoken",
         "payloadVersion":"",
         "endpoint":{
            "endpointId":"b38d964c-0b55-4b9a-8c0c-c537721bd2e5",
            "scope":{
               "token":"token",
               "type":"BearerToken"
            },
            "payload":{},
            "context":{
               "properties":[
                  {
                     "namespace":"Alexa.BrightnessController",
                     "value":75,
                     "name":"brightness",
                     "timeOfSample":"2023-09-08T05:30:10.410Z",
                     "uncertaintyInMilliseconds":3000
                  },
                  {
                     "namespace":"Alexa.PowerController",
                     "value":"OFF,
                     "name":"powerState",
                     "timeOfSample":"2023-09-08T05:30:10.410Z",
                     "uncertaintyInMilliseconds":3000
                  }
               ]
            }
         }
      }
   }
}

运行测试时，我从 https://developer.amazon.com/alexa/console

开始

错误：

"The endpoint could not be set to the Initial States required by the Test Case."

场景2： 假设初始亮度设置为100。

在第二种情况下，我将亮度设置为“SetBrightness”命令中指定的值。如果命令指示将亮度设置为 0，我将报告亮度值为零并关闭灯。

                {

                    "value": 100
                }
            ],
            "directive": {
                "header": {
                    "namespace": "Alexa.PowerController",
                    "name": "TurnOn"
                },

            },
            "actualCapabilityStates": [
                {
                    "namespace": "Alexa.BrightnessController",
                    "name": "brightness",
                    "value": 0
                }
            ]
},

在上面的EvaluationResults中，在我看来它想要返回100，这是问题setBrightness=0之前的值。

这里的问题是，当将亮度设置为（0）零时，会发出什么预期响应？ 稍后发出

ReportState

时预期值是多少？

Answer 1

对于场景 1：您的技能只需设置 value=0 并将 value=0 发送回 Alexa。 SetBrightness 是来自 Alexa（用户）的请求，用于将您的设备值设置为特定值。 对于场景 2： 似乎测试期望设备在打开时返回 value=100。但是，如果在设备关闭（值=0）期间询问设备状态报告，则设备应以当前状态（值=0）响应。
