Smoke tests 50% from 4 tests

Server-side errors Passed 1 test

🔹 Test weight: 20 | Just a short smoke test targeting errors on the server (in the Apache logs)
Even though everything seems fine, this is not an exhaustive test

SRP 0% from 2 tests

🔹 Tests weight: 20 | The single-responsibility principle applies for WordPress plugins as well - please make sure your PHP files perform no actions when accessed directly
Almost there! Just fix the following items
  • 2× PHP files perform the task of outputting text when accessed with GET requests:
    • > /wp-content/plugins/advertpreloader/templates/header_tpl.php
    • > /wp-content/plugins/advertpreloader/templates/footer_tpl.php
  • 2× GET requests to PHP files have triggered server-side errors or warnings:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/advertpreloader/index.php:15
    • > PHP Fatal error
      Uncaught Error: Call to undefined function _e() in wp-content/plugins/advertpreloader/templates/home_tpl.php:8

User-side errors Passed 1 test

🔹 Test weight: 20 | A shallow check that no browser errors were triggered
Everything seems fine, but this is not an exhaustive test


Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

The readme.txt file is an important file in your plugin as it is parsed by WordPress.org to prepare the public listing of your plugin
These attributes need your attention:
  • Donate link: Invalid URI ("")
The official readme.txt is a good inspiration

advertpreloader/index.php 85% from 13 tests

The main file in "Advert Preloader" v. 0.1 serves as a complement to information provided in readme.txt and as the entry point to the plugin
It is important to fix the following:
  • Description: If Twitter did it, so should we! Keep the description under 140 characters (currently 252 characters long)
  • Main file name: The principal plugin file should be the same as the plugin slug ("advertpreloader.php" instead of "index.php")
