Phase 17-04: Processing Node Component Tests - Summary

Completed Tasks

Task 1: Add LLMGenerateNode component tests

• Commit: 6669ee0
• File: src/components/__tests__/LLMGenerateNode.test.tsx
• Tests: 25 tests covering:
  • Basic rendering with title "LLM Generate"
  • Text input handle on left (for prompt connections)
  • Image input handle on left (for vision capabilities)
  • Text output handle on right
  • Provider selector with Google and OpenAI options
  • Model selector dropdown based on selected provider:
    • Google: Gemini 3 Flash, Gemini 2.5 Flash, Gemini 3.0 Pro
    • OpenAI: GPT-4.1 Mini, GPT-4.1 Nano
  • Provider change updates model to first available
  • Temperature slider rendering and editing
  • Idle state with "Run to generate" message
  • Loading state with spinner
  • Error state display with fallback "Failed" message
  • Output text display with regenerate and clear buttons
  • Regenerate button disabled when workflow is running
  • Clear button resets output, status, and error
  • Custom title editing functionality
  • Model fallback when current model is invalid for provider

Task 2: Add AnnotationNode component tests

• Commit: 1084931
• File: src/components/__tests__/AnnotationNode.test.tsx
• Tests: 24 tests covering:
  • Basic rendering with title "Annotate"
  • Image input handle on left
  • Image output handle on right
  • Empty state with "Drop, click, or connect" message
  • Drop zone with dashed border when no image
  • Source image display
  • Output image display (prefers output over source)
  • "Add annotations" hint when no annotations
  • Annotation count display ("Edit (N)")
  • Modal opening via image click
  • Existing annotations passed to modal
  • Remove button clears sourceImage, outputImage, annotations
  • Hidden file input for manual upload
  • Click triggers file input dialog
  • File upload with FileReader processing
  • Format validation (PNG, JPG, WebP only)
  • Size validation (<10MB limit)
  • Drag and drop handling
  • Custom title editing functionality

Key Implementation Notes

Mock Patterns Used

1. Workflow store mock: Selector pattern with mockUseWorkflowStore.mockImplementation
2. Annotation store mock: Separate mock for useAnnotationStore (only used by AnnotationNode)
3. Global mocks: alert, DataTransfer, FileReader for file handling tests
4. ReactFlowProvider wrapper: Required for all node components

LLMGenerateNode Specifics

• Provider-model relationship: Changing provider auto-selects first model for that provider
• Model fallback logic: Invalid model for current provider falls back to first available
• Temperature stored as float, displayed with 1 decimal place
• Output text preserved across regenerations until cleared

AnnotationNode Specifics

• Uses separate useAnnotationStore for modal state management
• openModal(nodeId, image, annotations) is the interface to annotation modal
• Display priority: outputImage > sourceImage
• Clear operation resets all three: sourceImage, outputImage, annotations
• Tests focus on component shell per plan guidance (no Konva internals)

Testing Approach

• Handle identification via data-handletype and CSS class patterns (target/source)
• Button identification via title attribute or SVG path patterns
• File validation messages tested via mock alert
• Remove button hidden with opacity-0 but still clickable in tests

Deviations from Plan

None. All tasks completed as specified.
