webapp-testing

The reviewed content documents a Playwright-based local testing toolkit and a helper that starts servers via operator-supplied commands. I found no direct evidence of malware or obfuscated malicious code in the provided fragment. The primary security concerns are: arbitrary command execution via the server helper, potential supply-chain exposure through npm or other lifecycle scripts invoked by those commands, and sensitive-data exposure via saved page content and screenshots. The documentation's recommendation to treat scripts as black boxes and to run them before reading their source is a notable operational risk. Before running helpers on untrusted projects, inspect the helper implementation (avoid shell=True patterns), sandbox server processes, and audit dependency install scripts and any captured artifacts.
