This tool's purpose is to find discrepancies between the Document Object Model (DOM) that a web server initially sends and the DOM that is actually displayed in a user's browser after JavaScript and other client-side scripts have run.
- Initial Capture: It first records the original DOM as it's delivered from the server.
- Client-Side Rendering: It then allows the page to fully load and render in a browser, capturing the final, modified DOM.
- Comparison Algorithm: The core of the tool is a comparison algorithm that checks for changes between the two versions. This can include: element additions or removals, attribute changes (e.g., a class being added or removed), text content modifications.
This process is crucial for web developers and quality assurance testers to:
- Debug JavaScript issues: Pinpoint exactly what a script is changing on the page. 🧐
- Ensure rendering accuracy: Verify that the page looks and behaves as intended.
- Detect unexpected changes: Identify any unintended side effects of client-side code.
- Monitor for security vulnerabilities: Catch malicious script injections that alter the page's structure.
