test: update parallel/interception tests for Cache Components #88354

wyattjoh · 2026-01-09T23:16:01Z

Summary

Make parallel routes and interception route tests compatible with Cache Components (PPR) to re-enable them in the test manifest. Tests now work with both __NEXT_CACHE_COMPONENTS=true and without it.

Changes

Added generateStaticParams() to dynamic route pages
Replaced export const dynamic = 'force-dynamic' with await connection() from next/server for Cache Components compatibility
Wrapped parallel route slots in <Suspense> boundaries to support PPR streaming
Updated tests to use waitForElementByCss() for streamed elements instead of assuming immediate availability
Renamed layout-edge.tsx to layout.fixture-edge.tsx for clarity

Testing

All 6 targeted tests pass with both Cache Components enabled and disabled (backwards compatible).

Make parallel routes and interception route tests compatible with Cache Components (PPR) by: - Adding generateStaticParams() to dynamic route pages - Using connection() instead of force-dynamic for dynamic behavior - Wrapping parallel route slots in Suspense boundaries - Using waitForElementByCss for streamed elements in tests - Renaming layout-edge.tsx to layout.fixture-edge.tsx for clarity
