参见图1，本实施例提供的一种动态可配置的应用层通信协议测试方法实现过程下：
101，根据串口通信协议，划分串口通信功能单元类别。
本步骤是串口通信功能单元类别划分的过程。
具体的，
1、抽象出串口通信协议的基本通信模式和协议指令处理模式。
2、根据基本通信模式和协议指令处理模式，划分串口通信功能单元类别。
例如功能单元类别包括通信模式单元，协议指令单元。
本步骤可以依据串口通信协议进行串口通信功能单元类别划分。
例如，采用基于可复用通信功能单元的实现方法，抽象出串口通信指令协议基本通信模式、协议指令处理模式，依据通信协议进行串口通信功能单元类别合理划分，本实施例中包含一种通信模式单元和两种协议指令单元，如表1所示。
表1
102，根据功能单元类别，建立通信功能单元和配置信息之间的对应关系。
本步骤是可复用功能单元及配置接口设计的过程。

2、对目标单元及配置接口进行设计，建立目标单元的配置信息接口。
3、建立目标单元与配置信息接口的映射关系。
本步骤可以依据功能单元类别设计可复用通信功能单元和对应配置信息接口，建立配置信息与通信功能单元的映射关系。
例如，根据串口通信功能单元类别划分结果，对识别出的单帧输出与单帧输入通信模式功能单元及配置接口进行设计，形成串口单帧输出与单帧输入通信模式功能单元，并建立相应CSV配置文件接口。通过对串口通信基本接口函数进行封装完成相应串口通信功能单元，实现发送一帧数据后回读一帧数据并判读的功能，功能单元采用统一接口参数，参数接口包含输入参数、输出参数、返回值。其中输入参数为可配置参数，具体见下表2，输出数据为回读的测试结果，由功能单元对照配置的判据进行自动比对判读，给出是否合格的结论，返回值为功能单元的执行状态。

其中，物理量数据信息包括但不限于：数据名称、类型、数据值、标度因子。
通过协议指令数据生成配置，可以在配置文件中配置好帧格式、物理量数据信息(数据名称、类型、数据值、标度因子等)，可通过串口应用数据生成功能单元模块动态获取发送数据。
可定义发送数据配置文件名为协议指令标识，应用数据生成功能单元通过通信模式功能单元输入的协议指令标识，经过处理模块，依据发送数据配置文件名提取待发送的数据，然后断数据类型，将物理量数据按不同数据类型与标度因子转换成待发送的字节数据，最后输出待发送的字节数据。
例如，配置接口如表3所示。
表3

在进行串口通信协议指令配置时，可采用CSV文件表格化形式对一条指令形成一个指令协议配置信息，将通信协议中所有指令项目采用配置信息的形式建立通信协议指令与协议指令单元配置信息的对应关系，例如，应用数据(DataS1)生成配置实例如下表6，应用数据解析与判读配置(DataR1)如下表7。
表6
| 字节 | 数据名称 | 数据类型 | 数据值 | 标度因子k | 标度因子b |
| 1 | 命令字节 | uchar8 | 0xE4 | 1 | 0 |
| 1 | 命令发送标识 | uchar8 | 0xA1 | 1 | 0 |
| 8 | 发送数据1 | double64 | 86.35 | 57.3 | 0 |

| 1 | 测试结果1 | uchar8 | 0xAA | 1 | 0 |
| 1 | 测试结果2 | uchar8 | 0xBB | 1 | 0 |
本步骤依据通信协议进行协议配置，一条指令形成一个指令协议配置信息，将通信协议中所有指令项目采用配置信息的形式建立通信协议与配置信息的对应关系。
104，根据通信功能单元和配置信息之间的对应关系，完成的配置，加载并执行配置信息。
本步骤是测试配置信息动态加载与执行过程。
具体实现时，从配置文件中顺序读取每一条配置信息后，执行如下步骤：
1、根据通信功能单元和配置信息之间的对应关系，确定读取的配置信息所对应的通信功能单元。
2、将读取的配置信息传递至对应的通信功能单元，基于完成的配置加载并执行配置信息。

2)基于通信模式配置，进行对应的通信功能单元与被测设备之间的通信，以便执行配置信息。
3)若通过通信获取到接收数据，则基于协议数据解析配置进行接收数据的解析判读，显示判读结果。
本步骤可以从配置文件中顺序读取每一条配置信息，并进行解析，判断对应的通信功能单元，并将配置信息传递至通信功能单元的接口参数，由通信功能单元完成当前通信指令执行。
例如，通过设计自动、单步、组合等多种测试模式，并建立与之相应的 配置文件映射关系。首先基于人机交互界面的用户选择操作(自动、单步、组合)信息，通过多模式处理单元统一关联相应的配置文件，从配置文件中顺序读取每一条配置信息，并进行解析，判断对应的通信功能单元，并将配置信息传递至通信功能单元的接口参数。然后通过应用数据生成单元处理生成待发送数据，通过通信模式功能单元进行与被测设备通信，完成当前通信指令执行，返回的结果通过应用数据解析与判读单元处理，并进行数据自动解析判读，最后进行界面显示。执行完成后进入下一项测试，所有测试项执行完成退出测试流程，串口通信协议指令多模式动态加载执行流程如图2所示。
参见图2，流程开始后，获取人机操作信息，进入多模式处理单元，独权配置文件测试信息。在应用数据生成单元中，读应用数据配置信息，应用数据生成。在基础通信模式单元中判断对应的通信功能单元。在应用数据解析与判读单元中，读应用数据解析配置信息，应用数据解析与判读。判断执行是否正常，如果不正常，则进行测试异常处理，如果正常，则进行测试信息提示。如果流程未结束，则进行下一测试项目，重复执行进入多模式处理单元的步骤及后续步骤。
测试过程中在后台存储测试过程的所有通信数据、测试日志信息，测试完成后输出测试报告，记录各测试项目的测试结果与测试是否合格的结论。测试过程中的通信数据和测试日志在测试流程任务执行中记录，测试日志包含时间戳和当前的操作，测试报告给出每个测试项目和对应的测试参数、要求值、实测值、结论。
本实施例提供的动态可配置的应用层通信协议测试方法与现有技术相比的优点在于，解决了大多面向具体通信协议通过对各通信协议指令逐一代码实现的方式，代码实现过程繁琐，带来的重复测试验证工作，效率低下且容易引发潜在问题。采用格式化表格配置的方式实现可复用串口通信协议功能单元参数配置接口，只需编写基本测试功能单元模块程序，通信协议指令以表格信息编辑的方式进行相关应用功能设计。实现了最大化减少串口通信协 议实现代码的编写工作，尤其对于通信协议指令数量大、测试流程序列长、测试项目、测试参数、判据易变的通信协议指令测试应用场景效果明显，提高代码复用率，方便移植和推广。
本实施例提供的动态可配置的应用层通信协议测试方法，可以提升地面综合测试中对被测系统或设备的应用层通信协议测试效率，解决目前串口应用层通信协议复杂、涉及的通信指令多、协议内容易变的测试应用场景下通信协议实现方式效率较低问题，实现对被测设备高效、可靠的串口应用层通信协议测试。
具体的，本实施例提供的动态可配置的应用层通信协议测试方法，通过采用可复用串口通信功能单元技术，设计串口协议基本通信模式功能单元、协议指令处理功能单元以及各功能单元动态配置接口，并通过串口通信协议指令多模式动态加载执行实现综合测试过程中应用层通信协议的动态可配置，减少繁琐的编码工作，提高综合测试效率。
本实施例提供的该方法，根据串口通信协议，划分串口通信功能单元类别；根据功能单元类别，建立通信功能单元和配置信息之间的对应关系；进行通信协议测试配置；根据通信功能单元和配置信息之间的对应关系，完成的配置，加载并执行配置信息，可以更加高效开展对被测系统和设备串口通信应用层协议各项功能的测试验证，减少繁琐的编码工作，提高对被测设备应用层通信协议测试效率。
