From 0800f714d87c7b4329a41788ae763379e03f894c Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 3 Apr 2026 19:33:01 +0000 Subject: [PATCH 1/2] test: increase component coverage and fix fetchPriority warning - Added comprehensive test suites for `CustomCursor`, `useTheme`, and `EmptyStateIllustrations`, achieving 100% coverage on these files. - Refactored `MarkdownRenderer` to use camelCase `fetchPriority` attribute to resolve React DOM invalid property warnings while preserving TypeScript type safety and accurate HTML output. Updated related tests accordingly. - Cleaned up Vitest mocks, handled RAF correctly, and removed unused variables causing TS warnings in tests.
