Smoke tests 75% from 4 tests

Server-side errors Passed 1 test

🔹 Test weight: 20 | This is a shallow check for server-side errors
Everything seems fine, however this is by no means an exhaustive test

SRP 50% from 2 tests

🔹 Tests weight: 20 | The single-responsibility principle: PHP files have to remain inert when accessed directly, throwing no errors and performing no actions
The following issues need your attention
  • 2× PHP files trigger server-side errors or warnings when accessed directly:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_shortcode() in wp-content/plugins/zoom-widget/zoom.php:15
    • > PHP Fatal error
      Uncaught Error: Class 'WP_Widget' not found in wp-content/plugins/zoom-widget/zoom_widget.php:3

User-side errors Passed 1 test

🔹 Test weight: 20 | Just a short smoke test targeting errors on the browser (console and network errors and warnings)
Everything seems fine, but this is not an exhaustive test
