 The test tree is organized with a clear backend/frontend split:
 
 - `tests/backend`
-  - backend unit tests
-  - backend integration tests
+  - backend unit tests, integration tests, and contract tests
+  - driven by `pytest`
   - regression tests directly related to `py-src/data_formulator/**`
 - `tests/frontend`
-  - frontend-related contract tests driven by `pytest`
-  - focused on request/response boundary behavior
-  - not intended for React component-level unit tests yet
+  - frontend unit tests powered by **Vitest** + **@testing-library/react** (jsdom)
+  - covers pure functions, Redux selectors, and React component rendering
+  - see `tests/frontend/README.md` for directory layout details
