 ### File Naming

- Test files: `ComponentName.spec.tsx` (same directory as component)
+- Test files: `ComponentName.spec.tsx` inside a same-level `__tests__/` directory
+- Placement rule: Component, hook, and utility tests must live in a sibling `__tests__/` folder at the same level as the source under test. For example, `foo/index.tsx` maps to `foo/__tests__/index.spec.tsx`, and `foo/bar.ts` maps to `foo/__tests__/bar.spec.ts`.
 - Integration tests: `web/__tests__/` directory
