Make Playground useful for testers

[adamziel]

Let's discuss making Playground more useful for WordPress testers (core, plugins, themes, OSS contributors, private plugins):

• WordPress.org’s PHP compatibility doc recommends a deprecated plugin reliant on wptide.org. Playground could be a useful alternative.
  • Idea 1: A doc page explaining how to test plugins with a specific PHP version
  • Idea 2: An alternative plugin with a UI testing wizard loading specific plugins and their combinations with a specific PHP version
• Tester resources explaining how to:
  • Test plugins and themes with Playground with different PHP and WordPress versions
• Features
  • Convenient shortcuts in @wp-playground/cli, such as npx @wp-playground/cli test-plugin <plugin name/path>, to spin a new site with that version. Make it easy to swap PHP and WP versions. This could also be useful as a browser extension. A companion package could detect and open plugin‑specific admin screens (add_menu_page, post edit) automatically and mark successes as ✅ for small/medium plugins, without requiring full E2E frameworks.

In pseudo-code, this is what I think the test tools should work:

// npx @wp-playground/cli test-plugin <plugin name/path>
for: all PHP versions
    for: all WP versions
        @wp-playground/cli server --mount-before-install=the_plugin:/wordpress/wp-content/K --wp=x --php=y
        curl /wp-admin and others
            PHP version. WP version: ✅ or ☹️
