PHPUnit - Testing Last Insert ID

PHP
1

Hello All

I need some help writing a test case to test the following code that checks if the record has been inserted successfully.


      $DB->Insert(db query here...);

      $lastInsertID = $DB->InsertID();

     if (!$lastInsertID) {
	throw new Exception('Unable to insert new record');
     }

Any help will be appreciated.

Thanks
