📝 Walkthrough

Walkthrough

This PR introduces a new React benchmark case (006-static-raw-text) that renders 100 identical static text nodes using runAfterLoadScript and root.render. The change includes a new TSX benchmark file, corresponding build configuration entry, and npm scripts for benchmarking and performance profiling.

Changes

Cohort / File(s)	Summary
New benchmark case benchmark/react/cases/006-static-raw-text/index.tsx	Adds new TSX file rendering 100 text nodes ("Hello, ReactLynx 🎉!") within runAfterLoadScript wrapper followed by RunBenchmarkUntilHydrate component.
Build configuration benchmark/react/lynx.config.js	Adds "006-static-raw-text" entry to source.entry configuration, including patchProfile.ts and the new benchmark case file.
Benchmark scripts benchmark/react/package.json	Adds bench:006-static-raw-text and perfetto:006-static-raw-text scripts for running the benchmark and performance profiling with --wait-for-id=stop-benchmark-true flag.
Test coverage configuration vitest.config.ts	Replaces targeted template-*/** exclusion with broader /tests/swc_snapshots/ pattern in coverage exclude list.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• benchmark/react/cases/006-static-raw-text/index.tsx: Straightforward benchmark implementation with repetitive text node creation; verify the runAfterLoadScript and root.render usage aligns with existing benchmarks (001-005).
• benchmark/react/lynx.config.js: Verify new entry key follows naming conventions and patchProfile.ts inclusion is consistent with other entries.
• vitest.config.ts: Confirm the broader snapshot exclusion pattern doesn't unintentionally suppress coverage for desired test snapshots.

🐰 Hop, hop! A sixth case hops in line,
One hundred texts in static design!
Lynx celebrates with emoji so bright,
Benchmarks and profiles—performance takes flight! ✨

Check name	Status	Explanation
Title Check	✅ Passed	The title "test: add static text case for bench" accurately describes the primary change across the four modified files. The PR adds a new benchmark test case (006-static-raw-text) for rendering static text, which requires creating the TSX benchmark file, updating the build configuration in lynx.config.js, and adding corresponding npm scripts in package.json. The title is concise, clear, and specific enough that a teammate scanning the repository history would immediately understand this is about introducing a new static text benchmark. The vitest.config.ts change appears to be a minor supporting adjustment to the coverage exclusion pattern rather than the main focus. The title directly reflects the core objective without unnecessary vagueness or noise.
