Block theme specific testing

[StevenDufresne]

Which block-based theme-specific tests are needed?

Ideas based on documentation: https://github.com/WordPress/gutenberg/tree/trunk/docs/how-to-guides/block-based-theme

• Validate experimental-theme.json
• Make sure block-template-part exists if included in block-templates. (It fails quietly)
• Make sure it doesn't include non-core blocks? (Edit: It can)

Reopening this issue to add more information and test ideas.

As I read the list of blockers and flags provided here https://make.wordpress.org/themes/2021/03/17/next-steps-on-themes-and-reviews/ non-core blocks are allowed.

For example, you may want to build a web shop with WooCommerce blocks.
The blocks will error in the editor until the plugin is installed, and should show nothing on the front.

The tutorial here is very outdated https://github.com/WordPress/gutenberg/tree/trunk/docs/how-to-guides/block-based-theme
The theme.json file can not be validated until it is more stable.
Planned changes: WordPress/gutenberg#29891

I do feel like Gutenberg should provide the validation for this file 🤔
