I wonder if there are tests that check that it is 100% compatible and not like 97%

Edit: ah, not even 97%

That said, the test suite is extensive: over 1,700 Vitest tests and 380 Playwright E2E tests, including tests ported directly from the Next.js test suite and OpenNext's Cloudflare conformance suite. We’ve verified it against the Next.js App Router Playground. Coverage sits at 94% of the Next.js 16 API surface
