How do I test payment processing for Black Friday?

As an e-commerce manager preparing for Black Friday, I'm deeply concerned about potential payment processing failures during the most critical sales period of the year. Previous experiences have shown how a single technical glitch can cost thousands in lost revenue and damage customer trust. I need a comprehensive strategy to stress test my payment systems, simulate high-traffic scenarios, and ensure seamless transaction processing during peak shopping hours. What are the most effective methods to validate and optimize payment infrastructure before the big day?
