public static function TestBase::filePreDeleteCallback in Drupal 8

Ensures test files are deletable.

Some tests chmod generated files to be read only. During TestBase::restoreEnvironment() and other cleanup operations, these files need to get deleted too.

Code

public static function filePreDeleteCallback($path) {

  // When the webserver runs with the same system user as the test runner, we
  // can make read-only files writable again. If not, chmod will fail while
  // the file deletion still works if file permissions have been configured
  // correctly. Thus, we ignore any problems while running chmod.
  @chmod($path, 0700);
