Yes they do have testing on Saturday but they stop giving out tickets for testing 30 min before closing on Saturday they will not give any ticket out after 1130
If you visit their website, you can click in their customer service center and see the wait time for all services (including learner's permits and other testing). Reminder, they are only open until 12 PM and the line gets long before they open. The last sevice ticket for testing is handed out 30 minutes before closing.
