function ExceptionTestSiteSubscriber::on500

Checks for special handling of errors inside Simpletest.

@todo The $headers array appears to not actually get used at all in the original code. It's quite possible that this entire method is now vestigial and can be removed.

File

core/lib/Drupal/Core/EventSubscriber/ExceptionTestSiteSubscriber.php, line 36
