Explain the real-world impact of performance failures and how testers save the day
Why Apps Crash on “Big Sale” Days: The Science of Load Testing Every year during mega sale events like Amazon Prime Day or during ticket rush hours on IRCTC, millions of users try to access the same platform at the same time. When systems are not prepared for such extreme traffic, apps slow down, freeze, or crash. For students learning software testing, this is where load testing becomes critical. For example, during Prime Day 2025, U.S. online sales reached $24.1 billion in just four days, showing how massive traffic spikes can be during sale events. At the same time, platforms experience sudden surges in users, requests, and payment transactions. Without proper testing, servers may overload and fail. A similar challenge occurs in India with railway ticket bookings. The IRCTC platform handles millions of ticket requests daily and aims for 99.98% uptime, highlighting how important reliable infrastructure is for large-scale systems. Why Apps Crash Apps fail mainly because of: Sudde...
