Sandbox testing uses test cases against sandbox inventory, ensuring the booking lifecycle functions without live bookings. Soft-launched Production testing, accessed via a specific URL, tests against production inventory, which is not publicly discoverable. Test cases include booking, canceling, modifying, and removing slots, with monitoring of feeds, booking server, and real-time updates. Prepare for launch by completing a questionnaire and the contact information form in Partner Portal, ensuring minimal failure rates and secure data transmission.\n"]]
