What Was Created

Main Test File: src/__tests__/integration/store-synchronization.test.tsx

• 19 integration tests focusing on store synchronization
• Tests document lifecycle, persistence, deletion, type management
• History and timeline integration per document
• Multi-document operations

Test Infrastructure:

• src/test/integration-utils.tsx - Helper functions and setup utilities
• src/test/test-helpers.ts - Store reset and default settings
• src/__tests__/integration/README.md - Documentation

Package Scripts:

"test:unit": "vitest run src/stores"
"test:integration": "vitest run src/__tests__/integration"

Testing Philosophy

These tests verify business logic integration (how stores work together) rather than UI interactions:

✅ What we test:

• Document creation across workspace, timeline, and history stores
• State synchronization between stores
• Document isolation and independence
• Type management and persistence
• Multi-document operations

❌ What we don't test:

• UI rendering or component behavior
• User interactions (clicks, typing, etc.)
• React Flow canvas operations
• Visual appearance

This approach ensures tests are:

• Fast (~38ms execution time)
• Reliable (no UI coupling, no flakiness)
• Maintainable (survive UI refactoring)
• Focused (test integration points, not implementation)

Test Coverage

Document Creation Integration (3 tests)

• Timeline data initialization
• Node/edge types persistence
• Required data structures

Document Persistence (2 tests)

• Data structure completeness
• Document order tracking

Document Isolation (2 tests)

• Independent document state
• Separate timeline data

Document Deletion (2 tests)

• Workspace and storage cleanup
• Active document switching

Type Management (2 tests)

• Custom node types
• Edge type updates

Document Duplication (1 test)

• Full data copy including custom types

History Integration (3 tests)

• Per-document history initialization
• Independent history stacks
• History cleanup on deletion

Document Renaming (2 tests)

• Title and metadata updates

Multi-Document Operations (2 tests)

• Creating many documents
• Sequential deletion

Key Learning: Store State Pattern

Critical Pattern - Always get fresh state after mutations:

// ✅ CORRECT
const docId = useWorkspaceStore.getState().createDocument('Test');
const doc = useWorkspaceStore.getState().documents.get(docId); // Fresh state

// ❌ WRONG
const store = useWorkspaceStore.getState();
const docId = store.createDocument('Test');
const doc = store.documents.get(docId); // Stale state!

Zustand updates state synchronously, but you need to call getState() again to see changes.

Running the Tests

# Run integration tests
npm run test:integration

# Run all tests
npm test

# Run with UI
npm run test:ui

Comparison with Existing Tests

Existing Unit Tests: 367 tests across 10 store files New Integration Tests: 19 tests in 1 file

Integration tests complement unit tests by testing how stores work together, catching bugs that unit tests miss.

Future Opportunities

Additional integration test areas:

• Graph-Timeline state synchronization
• Bibliography-Graph citation integration
• Search-Filter multi-store coordination
• Import/Export full workspace workflows

Conclusion

This integration test suite provides solid coverage of store synchronization in Vibe Kanban. The tests are:

• ✅ All passing (19/19)
• ✅ Fast (~38ms)
• ✅ Focused on business logic
• ✅ Independent of UI
• ✅ Production ready

The tests verify that the business logic layer works correctly without coupling to UI implementation, making them valuable for catching regressions while remaining maintainable.
