This Python script compares a baseline image with an actual image taken from a webpage. After any source code modifications, the visual changes can be easily compared through this script.
Ensure you have the following installed:
- Python 3.x
- Selenium (
pip install selenium) - Visual-comparison (
pip install visual-comparison)
You will also need the appropriate WebDriver for your browser. This example uses ChromeDriver.
- Set Up WebDriver: Ensure that the WebDriver executable (e.g.,
chromedriver) is in your system's PATH or specify its location in the script. - Update URLs and Credentials: Modify the script to target your specific webpage and use the appropriate login credentials.
- Open the Target Webpage: The script navigates to the target webpage.
- Login: Logs into the website using provided credentials.
- Take Screenshots: Takes a screenshot after login to visualize the changes.
- Compare Images: Compares the baseline image (expected) with the actual image taken after login.
- Save Result: Saves the comparison result and prints the similarity index.
- For creating baseline image, run 'baseline_image.py'
- Then image comparison can be performed through executing 'image_comparison.py'
