Support for integrated testing

[ellisjas]

Is your feature request related to a problem? Please describe

Would be great if LookBook supported testing of components. Doesn't need all the bells and whistles of Storybook, just the basics would be much appreciated. 🙏

Describe the solution you'd like

Introduce a testing framework integrated into LookBook that leverages the existing component previews as the basis for tests such as:

• Testing interactivity
• Accessibility audits
• Visual regression testing

Describe alternatives you've considered

Tested ViewComponent function using render_preview but this requires additional overhead.

Hey @ellisjas thank you for the feature request :)

A more integrated testing solution is definitely something I (and many others I'm sure) would love to see in Lookbook.

Are you thinking of this as tighter integration with an app's existing test suite but that runs outside of Lookbook, or more something that runs and reports on a per-component basis within the Lookbook UI? (The two might not be mutually exclusive but I'd be interested to know where you imagine the emphasis being).

• Testing interactivity

By this do you mean the ability to run client-side (JS) DOM interaction tests from within the Lookbook UI? Similar to how Storybook does it? Or something else? I'd personally love a storybook-style solution but it would be quite a big task to build something reliable that works for all 'flavours' of components I suspect.

I'm going to move this out of issues and into a discussion as that is where we are tracking feature requests now. But this is definitely something that would be good to get a range of peoples thoughts on as there is a lot of different ways something like this could potentially be implemented.
