✅ video processing test passed

Result: All unit tests passed without errors.

---

3. Integration Tests

Ran python quickstart.py:

✅ OpenCV 4.12.0 detected
✅ NumPy 2.2.6 detected
✅ Test video created (30 frames, 15 fps)
✅ Video processing completed
✅ Output file created (1,241,449 bytes)

Result: Full end-to-end workflow validated.

4. CLI Testing with test_video.mp4

Created and processed test_video.mp4:

# Created test video
python create_test_video.py
✅ test_video.mp4 created (5 seconds, 30 fps, 150 frames)

# Processed with CLI
python cli.py test_video.mp4 test_video_output.mp4
✅ Processing completed successfully
✅ Input: 3.0M
✅ Output: 6.2M (side-by-side format)

Verification:

• Input video: 640x480 pixels
• Output video: 1280x480 pixels (side-by-side)

6. Lane Detection Algorithm Verification

Test Input: test_video.mp4

• Format: Synthetic road video with lane markings
• Duration: 5 seconds
• FPS: 30
• Resolution: 640x480

Processing Pipeline:

1. ✅ Grayscale conversion
2. ✅ Gaussian blur (5x5 kernel)
3. ✅ Canny edge detection (thresholds: 50, 150)
4. ✅ ROI masking (trapezoid shape)
5. ✅ Hough line transform (rho=2, theta=π/180)
6. ✅ Lane separation by slope
7. ✅ Lane averaging and drawing (green lines, 3px)

Output Verification:

• ✅ Side-by-side format (1280x480)
• ✅ Original video on left half
• ✅ Lane detection on right half
• ✅ Green lane lines visible
• ✅ Smooth lane tracking

---

7. Cross-Platform Compatibility

Verified Features:

• ✅ Uses tempfile.gettempdir() for temporary files
• ✅ Uses os.path.join() for path construction
• ✅ No hard-coded platform-specific paths
• ✅ Error handling for keyboard interrupts
• ✅ Graceful exception handling

---
