How do I test site capacity for Black Friday?

As an e-commerce business preparing for Black Friday, I'm deeply concerned about my website's ability to handle massive traffic spikes. Previous years have shown how quickly sites can crash during high-demand shopping periods, potentially costing thousands in lost revenue. I need a comprehensive strategy to stress test my site's infrastructure, understand its breaking points, and ensure a smooth customer experience during the most critical sales period of the year. What systematic approaches can I use to validate and improve my site's performance before the big day?
