fix: support vitest 5 - #1802
Conversation
commit: |
📝 WalkthroughWalkthroughThe PR adds Vitest-version-aware project configuration and browser dependency optimization for Vitest 5. It updates the Vitest environment to use runtime types and restore global property descriptors based on the installed Vitest version. Browser tests now use non-exact text queries and compatible Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR updates Vitest integration for newer versions, but its type import may break declaration resolution for supported Vitest 4 installations. It is otherwise mergeable with explicit owner follow-up to use a type import compatible across the supported versions. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Use a Vitest 4-compatible type import.
The peer range supports Vitest 4.0.2, which does not export vitest/runtime. Both the Environment import and the typeof import('vitest/runtime') cast can therefore fail declaration resolution. Use a type import available across the supported Vitest versions.

The package was failing in vitest ecosystem-ci, so I fixed some breaking changes. This also inspired me to add a warning - vitest-dev/vitest#11120 (comment)
