+# PINE-29: E2E-003 - Index/Collection Management Tests
+
+## Summary
+
+Created comprehensive E2E tests for index/collection management operations across all three vector database providers (Pinecone, Qdrant, Weaviate).
+
+## Files Added
+
+### Test Suite
+- **`e2e/index-collection-management.spec.ts`**: Main test file with 21 test cases
+
+## Files Modified
+- **`E2E_TESTING.md`**: Updated documentation to include new test suite
+
+## Test Coverage
+
+### Pinecone Index Management (8 active tests)
+✅ **List indexes after connecting** - Verifies indexes can be listed via IPC with correct structure
+✅ **Refresh indexes list** - Tests refresh functionality returns consistent data
+✅ **View index stats** - Validates stats include namespaces, dimension, vector count
+✅ **Create new index** - Tests index creation with provider-specific settings (dimension, metric, serverless spec)
+✅ **Delete index** - Verifies deletion workflow and confirmation
+✅ **Handle index stats for empty index** - Tests edge case of empty indexes
+✅ **Handle errors for non-existent index** - Validates error handling
+✅ **List indexes with correct properties** - Comprehensive validation of index structure
+
+### Qdrant Collection Management (5 skipped tests)
+🔲 List collections after connecting (TODO)
+🔲 View collection stats (TODO)
+🔲 Create new collection with Qdrant-specific settings (TODO)
+🔲 Delete collection with confirmation (TODO)
+🔲 Refresh collections list (TODO)
+
+### Weaviate Class Management (5 skipped tests)
+🔲 List classes after connecting (TODO)
+🔲 View class stats (TODO)
+🔲 Create new class with Weaviate-specific settings (TODO)
+🔲 Delete class with confirmation (TODO)
+🔲 Refresh classes list (TODO)
+
+### Cross-Provider Tests (3 skipped tests)
+🔲 Handle empty collections/indexes list (TODO)
+🔲 Display provider-specific metadata correctly (TODO)
+🔲 Handle very large collection lists efficiently (TODO)
+
+## Implementation Details
+
+### Test Infrastructure
+- Uses existing `electron.setup.ts` helpers for app launch and profile management
+- Follows same pattern as `connection-flow.spec.ts` (E2E-002)
+- Tests use `window.electronAPI` for IPC communication
+- Proper cleanup with `cleanupTestProfiles()` and `closeElectronApp()`
+
+### Pinecone-Specific Testing
+- Requires `PINECONE_API_KEY` environment variable for cloud testing
+- Tests automatically skip if no real API key available
+- Creates and deletes test indexes (e.g., `test-index-{timestamp}`)
+- Validates serverless spec (cloud: aws, region: us-east-1)
+- Tests multiple distance metrics (cosine, euclidean, dotproduct)
+
+### TODO Items for Future Work
+1. **Qdrant Integration**: Activate tests when adapter system is integrated into backend
+2. **Weaviate Integration**: Activate tests when adapter system is integrated into backend
+3. **UI Testing**: Add tests for UI components (IndexesPanel, IndexConfigView)
+4. **Provider-Specific Metadata**: Test cloud/region display, quantization config, vectorizer settings
+5. **Performance Testing**: Validate UI responsiveness with large collection lists (50+)
+
+## Test Execution
+
+### Run all E2E tests:
+```bash
+pnpm run test:e2e
+```
+
+### Run only index management tests:
+```bash
+pnpm exec playwright test index-collection-management
+```
+
+### Run with UI mode (interactive):
+```bash
+pnpm exec playwright test index-collection-management --ui
+```
+
+### Run with real Pinecone API:
+```bash
+PINECONE_API_KEY=your-api-key pnpm exec playwright test index-collection-management
+```
+
+## Notes
+
+- **Pinecone Tests**: Fully functional, create/delete real indexes during testing
+- **Qdrant/Weaviate Tests**: Marked with `test.skip()` and detailed TODO comments
+- **Test Isolation**: Each test uses unique profile IDs and index names to avoid conflicts
+- **Error Handling**: Tests validate both success and error paths
+- **Documentation**: All tests include clear descriptions and comments
+
+## Next Steps
+
+1. Merge this branch to get E2E-003 tests into master
+2. When adapter system is integrated:
+   - Remove `test.skip()` from Qdrant tests
+   - Implement Qdrant-specific test logic
+   - Remove `test.skip()` from Weaviate tests
+   - Implement Weaviate-specific test logic
+3. Add UI-level tests for IndexesPanel and IndexConfigView components
+4. Consider adding snapshot tests for index metadata display
