ci: add draw controls test

[maartenbreddels]

This is using solara to run the test with a live frontend.

These things are difficult to test with galata, since we test user interaction.

In light of a future PR (see https://github.com/jupyter-widgets/ipyleaflet/issues/1165 for details) I think it's good to test one of the more complex widgets.

Failure is most likely not due to this PR.

Thanks Maarten!

I'm a bit skeptical about adding a new way to do visual regression testing to the repo. I'd prefer we either stick to galata or we move entirely to using solara testing.

you more or less have the same API with playwright

Hi Martin,

you more or less have the same API with playwright

Yes, but I've noticed pure python people having no idea what to do with the ui-tests, and have no idea how it works (it took me a while). Building tests that do interaction (like click a button) are basically a no-go for more Python people.

That said, I totally understand not wanting two systems. I could probably rewrite the notebook tests to use the solara test framework, but that would mean we don't have such a nice HTML report, since that is not available for Python yet: https://github.com/microsoft/playwright-python/issues/1296

Let me know what you think? Do you think its worth to give up the HTML report to have the option to do more complex UI tests from Python?

cheers,

Maarten
