Preparations

1. enable System Log in /system/config.php
2. make sure In-Link module is installed
3. make sure only In-Portal and Custom modules are enabled (in Configuration → Website → Modules section, when logged-in as root user)

Part 1

• in IDE:
  1. add trigger_error('test admin', E_USER_WARNING); before $application->Run(); line in /admin/index.php file
  2. add trigger_error('test front-end', E_USER_WARNING); before $application->Run(); line in /index.php file
  3. create /vendor/behat/mink/error_test.php file with <?php trigger_error('test vendor', E_USER_WARNING); content
  4. create /../error_test.php (in parent folder of In-Portal root folder) file with <?php trigger_error('test outside', E_USER_WARNING); content
  5. create /modules/custom/error_test.php file with <?php trigger_error('test module', E_USER_WARNING); content
  6. create /modules/in-link/error_test.php file with <?php trigger_error('test disabled module', E_USER_WARNING); content
  7. create '/modules/unknown-module' folder
  8. create /modules/unknown-module/error_test.php file with <?php trigger_error('test unknown module', E_USER_WARNING); content
  9. create /error_test_vendor.php file as copy from /index.php file, that will have all code, that comes after $application->Init(); replaced with require FULL_PATH . '/vendor/behat/mink/error_test.php';
  10. create /error_test_outside.php file as copy from /index.php file, that will have all code, that comes after $application->Init(); replaced with require FULL_PATH . '/../error_test.php';
  11. create /error_test_module.php file as copy from /index.php file, that will have all code, that comes after $application->Init(); replaced with require MODULES_PATH . '/custom/error_test.php';
  12. create /error_test_disabled_module.php file as copy from /index.php file, that will have all code, that comes after $application->Init(); replaced with require MODULES_PATH . '/in-link/error_test.php';
  13. create /error_test_unknown_module.php file as copy from /index.php file, that will have all code, that comes after $application->Init(); replaced with require MODULES_PATH . '/unknown-module/error_test.php';
