Component Testing Add-On

[vhscom]

This issue is to request addition of Playwright component testing to svelte-add to make set-up easier and better integrated with Svelte apps than the default init scripts provided by Playwright.

There're still decisions to be made and some related discussion here as noted by Ben McCann:
sveltejs/kit#5285. The takeaway I had from reviewing the linked issue is that there are trade-offs on using Playwright for component testing and, as a result, it may not be the default in create-svelte but more of an add-on functionality—which it may make sense never to show as an option to keep project scaffolding simple.

And here's an example from the Svelte dev who made the very awesome meta tags component:

EDIT:

https://youtu.be/-GKRH0KQ_j0 is a Svelte Sirens presentation which shows how to component test with Cypress. After a little trial and error with Playwright Component Testing I can see why they call it experimental as it's a bit painful to get a component mounted at the current time. Learned about the video here from the following very helpful tutorial which covers Playwright setup for Svelte and provides additional component testing resources: https://davipon.hashnode.dev/test-svelte-component-using-vitest-playwright
