What is Load Testing?
Simulating many simultaneous users to test how your application performs under heavy traffic.
Why It Matters
Load testing reveals performance bottlenecks before real users experience slowdowns or crashes.
Real-World Example
Simulating 10,000 concurrent users to check if your site stays responsive during a product launch.
“Understanding terms like Load Testing matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
