Smoke tests 75% from 4 tests

Server-side errors Passed 1 test

🔹 Test weight: 20 | This is a short smoke test looking for server-side errors
Even though no errors were found, this is by no means an exhaustive test

SRP 50% from 2 tests

🔹 Tests weight: 20 | SRP (Single-Responsibility Principle) - PHP files must act as libraries and never output text or perform any action when accessed directly in a browser
Almost there! Just fix the following items
  • 1× PHP files perform the task of outputting text when accessed with GET requests:
    • > /wp-content/plugins/wc-qr-codes/includes/lib/phpqrcode/index.php

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
