Currently, the PHP project's testing framework lacks more specialized support for the automated testing of the FastCGI Process Manager (FPM), especially for issues that require higher load. We propose to develop an FPM/SAPI testing tool that can execute all applications and set expectations on the produced logs and server responses. This tool will be connected with a load testing tool (e.g., wrk) to simulate real-world usage and load.

The work has started in the https://github.com/bukka/wst repository with the plan to move it to the PHP GitHub organization when ready.
