You can use Performance Testing Service (PTS) to conduct performance testing on WeChat mini programs.
You can use PTS to conduct performance testing on applications that communicate by using HTTP or HTTPS regardless of whether the client is an app developed by Alibaba Cloud, a mobile web page, a PC web page, a WeChat mini program, or C/S software. For examples on how to perform performance testing on WeChat mini programs, see How do I perform performance testing on WeChat mini programs?
To conduct performance testing, you must determine the details of the requests, including the request body, the headers, and the parts of the request to be parameterized. If you cannot determine the request body, use a cloud recording feature provided by the specified PTS resource package to capture real requests sent to the server and then conduct debugging and performance testing.
