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 Structure

Frontend Tests

Location: frontend/src/lib/

Module	Test File	Tests	Status
sidebar.js (store)	`stores/__tests__/test_sidebar.js`	7	✅ PASS
taskDrawer.js (store)	`stores/__tests__/test_taskDrawer.js`	10	✅ PASS
activity.js (store)	`stores/__tests__/test_activity.js`	7	✅ PASS

Backend Tests

Location: backend/src/

Module	Test File	Tests	Status
DashboardsAPI	`api/routes/__tests__/test_dashboards.py`	-	⚠️ Import Issues
DatasetsAPI	`api/routes/__tests__/test_datasets.py`	-	⚠️ Import Issues
ResourceService	`services/__tests__/test_resource_service.py`	-	⚠️ Import Issues

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

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

Backend

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

Running Tests

Frontend

cd frontend && npm run test

Backend

cd backend && .venv/bin/python3 -m pytest tests/ -v
