+### Vitest Golden Tests
+
+```bash
+cd vitest
+pnpm install --ignore-workspace
+export BRAINTRUST_API_KEY=<your-key>  # Required to send spans to Braintrust
+export OPENAI_API_KEY=<your-key>       # Required for OpenAI tests
+pnpm test
+```
+
+This will run the Vitest wrapper golden tests which validate that the `wrapVitest` integration correctly traces test execution to Braintrust. Tests include both basic logging and OpenAI API calls to verify wrapper composition.
