e2e folder in SvelteKit template isn't type-checked

[teemingc]

Currently, the Svelte template adds an e2e directory for Playwright tests. However, this directory isn't type-checked (see sveltejs/kit#15254). We have 3 options:

1. Rename "e2e" to "tests" which is covered by the generated tsconfig.json
2. Change the generated tsconfig.json to recognise the "e2e" directory
3. Include it via the SvelteKit typescript config option

Yes we should fix this!

Some random points:

• playwright.config.ts is today looking at this folder e2e
• e2e & vitest will do:

---

Me, I'm always changing stuff to have e2e tests close to the route, so I would move e2e/demo.test.ts to src/routes/page.svelte.e2e.ts and update the conf to look for tests ending with e2e.ts
Bonus, no confusion between unit & e2e files,

	files
unit	.{test,spec}.{js,ts}
e2e	.e2e.{js,ts}

And it would solve typecheck.

What do you think?

I tried to solved by simply renaming it in PR #919
