## Overview

This document describes the testing strategy for the Superset-Style UX Redesign feature. Tests follow the Fractal Co-location strategy, with tests placed in `__tests__` subdirectories relative to the code they verify.

## Test Configuration

### Frontend (Vitest)

Configuration: `frontend/vitest.config.js`

- Environment: jsdom
- Test location: `src/lib/**/__tests__/*.js`
- Mocks: `$app/environment`, `$app/stores`, `$app/navigation`
- Setup file: `src/lib/stores/__tests__/setupTests.js`

### Backend (Pytest)

- Tests run from `backend/` directory
- Virtual environment: `.venv/bin/python3`

---

## Known Issues

### Frontend

1. **WAITING_INPUT status test** - Fixed: Tests now correctly expect WAITING_INPUT to NOT be counted as active (only RUNNING tasks count as active per contract)

2. **Module caching** - Fixed: Added `vi.resetModules()` and localStorage cleanup in test setup

### Backend

1. **Import errors** - Pre-existing: Tests in `src/api/routes/__tests__/` fail with `ImportError: attempted relative import beyond top-level package`. These tests need refactoring to use correct import paths.

2. **Log persistence tests** - Pre-existing: 9 errors in `tests/test_log_persistence.py`

---

## Running Tests

### Frontend
```bash
cd frontend && npm run test
```

### Backend
```bash
cd backend && .venv/bin/python3 -m pytest tests/ -v
```
