📸 PanonPy

PanonPy is a simple, modular Python library for visual regression testing by comparing images differences and generating HTML report

✨ Features

• Compare two images (actual vs baseline)
• Auto-generate HTML report with images
• Fail the test if images differ (optional)
• Pytest integration ready
• CLI support (coming soon)

📦 Installation

pip install panonpy

🚀 How to Use

Basic Usage

from panonpy.panonpy import PanonPy

# Create a PanonPy instance
tester = PanonPy(output_dir='results', fail=True)

# Compare two images
tester.compare(
    actual_image_path='path/to/home_page_screenshot.png',
    baseline_image_path='path/to/baseline_home_page.png',
    test_name='home_page_test',
    threshold=0.01  # Allow 1% difference
)

Install Development

Make sure you have Poetry installed. Clone the repository:

git clone https://github.com/FachrulCH/panonPy.git
cd panonpy
poetry install --with test

Result

• Copies actual, baseline, and diff images into output_dir (default: 'results')
• Generates a VisualTestsResult.html report with:
  • Green rows for identical images
  • Red rows for different images
  • Yellow rows for newly created baselines
  • Clicking an image in the report opens a full-size popup preview
