feat: adding solid component testing support

[cuixiaorui]

• Closes Solid Mount Support For Component Test #24586

User facing changelog

Additional details

I refer to the PR

Implemented cypress component test support for solid

TODO

1. No documentation written (similar to this document https://docs.cypress.io/guides/component-testing/quickstart-svelte#Configuring-Component-Testing)
2. did not generate changelog (I do not know how to complete this operation, I hope someone can help me)

Steps to test

You can scaffold a new solid project with npm init vite and choose Solid. Then you can point yarn cypress:open at the solid project and get to testing!

There are also some system tests in system-tests/test/component_testing_spec.ts that test both webpack and vite.

How has the user experience changed?

Hi @cuixiaorui, first, thank you for this PR. I'm going to close it without review, in light of this comment here: #24250 (comment) and @lmiller1990's comment here: #24494 (comment)

To summarize: we don't intend to add support for new frameworks to the core Cypress app in the short term. But we do intend to make it easier to write community-owned mount adapters that are as easy for users to adopt as the "officially" supported framework.

[lmiller1990]

I am looking into a public API to let you support Solid (and other frameworks) directly in Cypress. Follow progress: #24991

[JessicaSachs]

@lmiller1990 or @baus is Solid still out of scope? I was literally about to make an issue/offer a PR when I saw there already was one! First class support for something that's topping the State of JS survey seems like a good move. 😄

I just asked a similar question of the Vite team about including it in their starter. They're probably going to have a "minimum number of npm downloads" stat as a metric on if they'll take on the maintenance burden. Seems like a reasonable approach to deciding if something will be 3rd party.

@JessicaSachs It is on our roadmap to provide support for thirdparty framework implementations including documentation. We would like to use that to encourage support for Solid and other emerging frameworks.

[lmiller1990]

I am working on letting third parties slot into launchpad/onboarding right now, I was thinking Solid a good first candidate for "how to plug into launchpad".

There are a few Solid mount adapters around, so you can definitely use CT with it already. There is also SolidStart - the meta framework for Solid, and that should also be pretty easy to support since it's just Vite under the hood.

[JessicaSachs]

Yeah, the ecosystem also is struggling with Storybook integration, so there's a clear need for a sandbox that enables component-driven development in the meantime.

LMK when I should take a look and I'll play around.
