Status: Draft (The final form of this may move to a blog post or a full repo.)

This describes how to set up the repos for WordPress/wordpress-develop, WordPress/gutenberg, and WordPress/performance in one single place all using their own built-in environments (in Docker). Importantly, the latter two repos (for plugins) are configured to use the core files from the repos for both their development and tests environments.

Benefits:

1. WordPress core files are shared across all environments, including when running unit tests. So if you run PHPUnit tests for Gutenberg or Performance Lab, any core changes you've made will be reflected. This resolves a big painpoint with trying out core patches in plugin unit tests.
2. Plugins, mu-plugins, and themes and are shared across all environments, although you can add additional environment-specific extensions in your `.wp-e

 * Plugin URI: https://gist.github.com/westonruter/f9e67442c674c3176b95cd1ed0e784c1
 * Description: In classic themes script modules are forced to print in the footer since the HEAD is rendered before the rest of the page, so it is not yet known what script modules will be enqueued. This can be fixed with output buffering. This is a demonstration plugin for Core Trac ticket #43258 which adds output buffering for the rendered template.
