## 6. TEST EXECUTION ISSUES & FIXES

### Issue 1: WebSocket Store Tests Failing
```
❌ should connect websocket
❌ should disconnect websocket
❌ should subscribe to a channel
❌ should unsubscribe from a channel

Root Cause: Async mocking of WebSocket not properly synchronized
Fix: Wrap async operations in waitFor() or use fakeTimers
```

### Issue 2: Component Rendering Failures
```
❌ CreateItemForm: 9/12 tests failing
❌ CreateProjectForm: 2/5 tests failing

Root Cause:
  1. Missing act() wrapper for state updates
  2. Canvas context not mocked for graph visualization
  3. Async operation timing issues

Fix:
  1. Wrap state updates in act(() => { ... })
  2. Mock HTMLCanvasElement.getContext()
  3. Use userEvent.waitFor() for async actions
```

### Issue 3: Canvas Context Not Available
```
Error: HTMLCanvasElement's getContext() method:
       without installing the canvas npm package

Root Cause: Graph visualization components use canvas
Fix:
  1. Install 'canvas' package or
  2. Mock canvas in test setup
  3. Skip visual rendering in tests
```
