We currently only fallback to the global `runtime` option if the page actually **needs** a runtime (not statically optimizable). That happens for SSG (ISR) and SSR for pages/. But for app/, we will always need a `runtime` to render server components. Also in this PR, I improved the tests to actually **test** the runtime to ensure it has `globalThis.EdgeRuntime` so it's not running in the Node.js runtime ([ref](https://edge-runtime.vercel.app/features/available-apis#addressing-the-runtime)). ## Bug - [ ] Related issues linked using `fixes #number` - [x] Integration tests added - [ ] Errors have a helpful link attached, see `contributing.md` ## Feature - [ ] Implements an existing feature request or RFC. Make sure the feature request has been accepted for implementation before opening a PR. - [ ] Related issues linked using `fixes #number` - [ ] Integration tests added - [ ] Documentation added - [ ] Telemetry added. In case of a feature if it's used or not. - [ ] Errors have a helpful link attached, see `contributing.md` ## Documentation / Examples - [ ] Make sure the linting passes by running `pnpm lint` - [ ] The "examples guidelines" are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md) Co-authored-by: JJ Kasper <jj@jjsweb.site>
