基于在线调试的串口通信协议测试方法

以测试某型数据传输数字地图子系统中数字地图生成模块软件的RS485通信协议为例，提出了两种基于在线调试的串口通信协议的测试方法。这两种方法不仅简单易行地解决了某些测试环境中无法利用串口调试工具进行串口通信协议测试的问题，还为软件测试领域提出了一种通过在线调试技术解决问题的思路。

Serial Communication Protocol Testing MethodsBased on On-line Debugging

Taking the testing of RS485 communication protocol of Digital Map Generation Module in Data Transfer and Digital Map System as an example, this paper puts forward two methods for serial communication protocol testing based on on-line debugging. These methods not only solves the problem that serial debug tools cannot be used in the testing of serial communication protocol in some testing environments, but also provides a new idea of solving problems with on-line debugging technology in software testing field.
