+// or use a markdown library with XSS protection +``` + +## Common Patterns in This Project + +### Node Operations + +```typescript +// Adding a node +const addNode = useNodeStore(state => state.addNode); +addNode({ + id: generateId(), + type: 'custom_node', + position: { x: 0, y: 0 }, + data: { + properties: {}, + workflow_id: workflowId + } +}); + +// Updating node data +const updateNode = useNodeStore(state => state.updateNode); +updateNode(nodeId, { + data: { properties: { ...newProperties } } +}); +``` + +### Edge/Connection Operations + +```typescript +const addEdge = useNodeStore(state => state.addEdge); +addEdge({ + id: `${sourceId}-${targetId}`, + source: sourceId, + target: targetId, + sourceHandle: 'output', + targetHandle: 'input' +}); +``` + +### Asset Upload + +```typescript +const { uploadAsset } = useAssetUpload(); + +const handleFileUpload = async (file: File) => { + try { + const asset = await uploadAsset(file, workflowId); + console.log('Uploaded:', asset); + } catch (error) { + console.error('Upload failed:', error); + } +}; +``` + +## What NOT to Do + +### ❌ Don't use deprecated React patterns + +```typescript +// ❌ Bad +class MyComponent extends React.Component { } + +// ❌ Bad +componentWillMount() { } + +// ✅ Good - use functional components and hooks +const MyComponent: React.FC = () => { }; +``` + +### ❌ Don't mutate state directly + +```typescript +// ❌ Bad +state.nodes.push(newNode); + +// ✅ Good +setState({ nodes: [...state.nodes, newNode] }); +``` + +### ❌ Don't use inline functions in JSX (when passed to child components) + +```typescript +// ❌ Bad - creates new function on every render +
}> + + + ); + + expect(screen.getByText('Error occurred')).toBeInTheDocument(); + spy.mockRestore(); +}); +``` + +### Testing Context Providers + +```typescript +it('provides context value to children', () => { + const TestComponent = () => { + const value = useMyContext(); + return
{value}
; + }; + + render( + + + + ); + + expect(screen.getByText('test value')).toBeInTheDocument(); +}); +``` + +### Testing React Query / TanStack Query + +```typescript +import { QueryClient, QueryClientProvider } from '@tanstack/react-query'; + +const createTestQueryClient = () => new QueryClient({ + defaultOptions: { + queries: { retry: false }, + mutations: { retry: false } + } +}); + +it('fetches and displays data', async () => { + const queryClient = createTestQueryClient(); + + render( + + + + ); + + await waitFor(() => { + expect(screen.getByText('Loaded data')).toBeInTheDocument(); + }); +}); +``` + +### Testing ReactFlow Components + +```typescript +import { ReactFlowProvider } from '@xyflow/react'; + +it('renders node in ReactFlow', () => { + render( + + + + ); + + expect(screen.getByText('Test Node')).toBeInTheDocument(); +}); +``` + +## Best Practices + +### 1. Test Behavior, Not Implementation + +❌ **Bad:** +```typescript +it('sets internal state', () => { + const component = shallow(); + expect(component.state('count')).toBe(0); +}); +``` + +✅ **Good:** +```typescript +it('displays initial count', () => { + render(); + expect(screen.getByText('Count: 0')).toBeInTheDocument(); +}); +``` + +### 2. Use Accessible Queries + +Prefer queries that mirror how users interact with your app: + +```typescript +// Priority order (best to worst): +screen.getByRole('button', { name: /submit/i }) // Best +screen.getByLabelText(/username/i) // Good for forms +screen.getByPlaceholderText(/enter name/i) // OK +screen.getByText(/click me/i) // Common +screen.getByTestId('custom-element') // Last resort +``` + +### 3. Keep Tests Independent + +```typescript +// Bad - tests depend on each other +describe('Counter', () => { + let store; + + it('starts at 0', () => { + store = createStore(); + expect(store.getState().count).toBe(0); + }); + + it('increments', () => { + store.getState().increment(); // Depends on previous test + expect(store.getState().count).toBe(1); + }); +}); + +// Good - each test is independent +describe('Counter', () => { + let store; + + beforeEach(() => { + store = createStore(); + }); + + it('starts at 0', () => { + expect(store.getState().count).toBe(0); + }); + + it('increments from initial state', () => { + store.getState().increment(); + expect(store.getState().count).toBe(1); + }); +}); +``` + +### 4. Use Descriptive Test Names + +```typescript +// Bad +it('works', () => { /* ... */ }); +it('test 1', () => { /* ... */ }); + +// Good +it('displays error message when API call fails', () => { /* ... */ }); +it('disables submit button while form is submitting', () => { /* ... */ }); +it('filters nodes by search term in case-insensitive manner', () => { /* ... */ }); +``` + +### 5. Don't Test External Libraries + +```typescript +// Bad - testing MUI component +it('renders MUI Button', () => { + render(); + expect(screen.getByRole('button')).toBeInTheDocument(); +}); + +// Good - testing your component's integration +it('calls onSave when save button is clicked', async () => { + const onSave = jest.fn(); + const user = userEvent.setup(); + + render(); + await user.click(screen.getByRole('button', { name: /save/i })); + + expect(onSave).toHaveBeenCalled(); +}); +``` + +### 6. Clean Up Side Effects + +```typescript +afterEach(() => { + // Clear all mocks + jest.clearAllMocks(); + + // Restore spies + jest.restoreAllMocks(); + + // Clean up timers + jest.clearAllTimers(); +}); +``` + +### 7. Use waitFor for Async Assertions + +```typescript +// Bad +it('loads data', async () => { + render(); + await new Promise(resolve => setTimeout(resolve, 100)); // Flaky! + expect(screen.getByText('Data')).toBeInTheDocument(); +}); + +// Good +it('loads data', async () => { + render(); + await waitFor(() => { + expect(screen.getByText('Data')).toBeInTheDocument(); + }); +}); +``` + +### 8. Prefer User Events Over FireEvent + +```typescript +// OK +fireEvent.click(button); + +// Better - more realistic +const user = userEvent.setup(); +await user.click(button); +``` + +## CI/CD Integration + +The project uses GitHub Actions for continuous integration. The workflow is defined in `.github/workflows/test.yml`. + +### Workflow Steps + +1. **Type Check**: `npm run typecheck` +2. **Lint**: `npm run lint` +3. **Test**: `npm test` + +### Running Locally as CI Does + +```bash +# Simulate CI environment +npm ci # Use exact package-lock.json versions +npm run typecheck # Must pass +npm run lint # Must pass +npm test # Must pass +``` + +### Pre-commit Hooks + +The project uses Husky for pre-commit hooks: + +```bash +# Automatically runs before commit +npm run typecheck +npm run lint +npm test +``` + +## Troubleshooting + +### Common Issues + +#### 1. Tests Timeout + +```typescript +// Increase timeout for slow tests +it('slow operation', async () => { + // ... +}, 10000); // 10 second timeout +``` + +#### 2. Canvas/WebGL Errors + +Canvas is mocked in `jest.setup.js`. If you see canvas-related errors: +- Check that the mock is properly loaded +- Verify `jest.config.ts` has correct canvas mapping + +#### 3. Module Not Found + +Add to `jest.config.ts` moduleNameMapper: + +```typescript +moduleNameMapper: { + '^@/(.*)$': '/src/$1', + // Add your pattern here +} +``` + +#### 4. React State Update Warnings + +```typescript +// Wrap state updates in act() +act(() => { + store.getState().updateValue('new value'); +}); + +// Or use waitFor for async updates +await waitFor(() => { + expect(screen.getByText('Updated')).toBeInTheDocument(); +}); +``` + +#### 5. Memory Leaks + +```typescript +// Always clean up subscriptions +let unsubscribe: () => void; + +beforeEach(() => { + unsubscribe = store.subscribe(() => {}); +}); + +afterEach(() => { + unsubscribe(); +}); +``` + +### Debug Utilities + +```typescript +// Print DOM tree +import { screen } from '@testing-library/react'; +screen.debug(); // Prints current DOM +screen.debug(screen.getByRole('button')); // Prints specific element + +// Log available roles +import { logRoles } from '@testing-library/react'; +const { container } = render(); +logRoles(container); + +// See what queries are available +screen.getByRole(''); // Shows all available roles in error message +``` + +### Running Single Test File + +```bash +npm test -- src/stores/__tests__/NodeStore.test.ts +``` + +### Running Tests in VSCode + +Install Jest extension and use: +- Click "Run" above test/describe blocks +- Set breakpoints for debugging +- View coverage inline + +## Resources + +- [Jest Documentation](https://jestjs.io/) +- [React Testing Library](https://testing-library.com/react) +- [Testing Library Queries](https://testing-library.com/docs/queries/about) +- [User Event Documentation](https://testing-library.com/docs/user-event/intro) +- [Jest DOM Matchers](https://github.com/testing-library/jest-dom) +- [Common Testing Mistakes](https://kentcdodds.com/blog/common-mistakes-with-react-testing-library) + +## Contributing + +When adding new features: + +1. ✅ Write tests for new components, hooks, and utilities +2. ✅ Maintain or improve code coverage +3. ✅ Follow existing test patterns +4. ✅ Update this documentation if adding new test patterns or mocks +5. ✅ Ensure all tests pass before committing: `npm test` diff --git a/web/TEST_HELPERS.md b/web/TEST_HELPERS.md new file mode 100644 index 000000000..709d73d42 --- /dev/null +++ b/web/TEST_HELPERS.md @@ -0,0 +1,691 @@ +# Test Helpers and Utilities Reference + +Quick reference guide for common test utilities, helpers, and patterns used in the NodeTool web application tests. + +## Table of Contents + +1.
