+# Tests
+
+Integration tests for mcp-familywall.
+
+## Prerequisites
+
+Tests require valid Family Wall credentials to run against the live API.
+Credentials are loaded from:
+
+1. **OS Keyring** (recommended) — set via `mcp-familywall setup`
+2. **Environment variables** — `FW_EMAIL` and `FW_PASSWORD`
+
+## Running Tests
+
+```bash
+uv run pytest tests/
+```
+
+For verbose output:
+
+```bash
+uv run pytest tests/ -v
+```
+
+## Test Coverage
+
+- Circles management (create, list, update, delete, members)
+- Lists and tasks (CRUD operations)
+- Categories (system and custom)
+- Recipes and meal planning
+- Activity feed and reactions
+- Date validation and error handling
+
+## Notes
+
+- Tests create temporary circles, lists, and tasks for verification
+- All test objects are cleaned up after execution
+- Do not run tests against production data — use test credentials only
+- Some tests are marked as skipped if premium features are unavailable
