An AJAX HTTP error occurred. HTTP Result Code: 200 I'm trying to Run the Test from Administrative User, and it bring me below Error message:


  An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging
  information follows. Path:
  /drupal7.50/batch?render=overlay&amp;id=18&amp;op=do StatusText: OK
  ResponseText: Fatal error: Maximum execution time of 30 seconds
  exceeded in C:\xampp\htdocs\drupal7.50\includes\database\database.inc

How can I fix that?
Increase your PHP max_execution time in php.ini
