Playwright
Microsoft's open browser framework supports reliable waits, network interception, screenshots, video, traces, and several languages.
Why use it
It covers WebGL boot, menus, accounts, stores, and accessibility flows with reproducible CI evidence.
Where it fits
Use testing, performance, accessibility, and diagnostic tools to remove problems players will notice.
What to check
Canvas gameplay usually needs test hooks or visual assertions; browser emulation does not replace real mobile and GPU coverage.
