# Notebook Components Test
> Testing the split NotebookViewer components
 🧪 Notebook Component Split Test # This page tests the refactored NotebookViewer components to ensure all functionality works correctly after the split.
Test Notebook # Test Markdown Cell # This is a markdown cell to test the split components.
Cell detection should work Headers should be added automatically Navigation should work with keyboard State should persist properly python # Python test code import numpy as np import pandas as pd # Create test data data = np.random.randn(100, 3) df = pd.DataFrame(data, columns=['A', 'B', 'C']) print("DataFrame shape:", df.shape) print(df.head()) text DataFrame shape: (100, 3) A B C 0 1.234 -0.567 0.890 1 -0.123 1.456 -0.789 2 0.456 -1.234 0.567 3 -0.789 0.123 1.234 4 1.567 -0.890 0.123 python # Another test code cell import matplotlib.pyplot as plt # Create a simple plot plt.figure(figsize=(8, 6)) plt.plot([1, 2, 3, 4], [1, 4, 2, 3]) plt.title('Test Plot') plt.xlabel('X axis') plt.ylabel('Y axis') plt.show() This is a raw cell for testing. It should be detected and handled correctly.
Raw cells don’t execute - they’re just text.
Manual Test Instructions # Navigation Test: Use arrow keys or j/k to navigate between cells Collapse Test: Click cell headers or toggle buttons to collapse/expand Copy Test: Use copy buttons or Ctrl+Shift+C to copy cell content Keyboard Shortcuts: Try Ctrl+Shift+E to expand/collapse all Accessibility: Test with screen readers and keyboard-only navigation Expected Results # If the component split worked correctly, you should see:
✅ Cell headers automatically added ✅ Copy buttons in code cells ✅ Toggle buttons for collapsible cells ✅ Keyboard navigation working ✅ ARIA attributes properly set ✅ State persistence (collapsed cells stay collapsed on refresh)
