How to test UI changes?

[lilfrootyloops]

Are there any tools we can use to test changes in the <canvas> that are caused by Cytoscape.js? I've tried searching for any existing libraries that may do so, but it doesn't appear that there are any.

Playwright, or any other general tool that allows for pixel-perfect, screenshot-based testing:

Thanks for the suggestion & letting me know about pixel-perfect, screenshot-based testing.
