Smoke tests 75% from 4 tests

Server-side errors Passed 1 test

🔹 Test weight: 20 | A shallow check that no server-side errors were triggered
Everything seems fine, however this is by no means an exhaustive test

SRP 50% from 2 tests

🔹 Tests weight: 20 | A shallow check of the single-responsibility principle; PHP files should perform no action - including output of placeholder text - and trigger no errors when accessed directly
Please take a closer look at the following
  • 2× PHP files trigger server errors when accessed directly:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_filter() in wp-content/plugins/codeqrcode-adsense/codeqrcode-adsense.php:33
    • > PHP Fatal error
      Uncaught Error: Call to undefined function get_option() in wp-content/plugins/codeqrcode-adsense/codeqrcode-adsense-admin.php:17

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

Optimizations

Plugin configuration 90% from 29 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
Attributes that require attention:
  • Tags: Too many tags (22 tag instead of maximum 10); only the first 5 tags are used in your directory listing
  • Plugin Name: Please replace "Plugin Name" with the name of your plugin on the first line ( === codeqrcode-adsense === )
The official readme.txt is a good inspiration

codeqrcode-adsense/codeqrcode-adsense.php 92% from 13 tests

The primary PHP file in "QRCode Generator - Adsense" version 2.1.1 is used by WordPress to initiate all plugin functionality
It is important to fix the following:
  • Description: Please don't use more than 140 characters for the plugin description (currently 265 characters long)
