What is performance testing and why is it important?

Performance testing is a type of testing to determine how a system performs in terms of responsiveness and stability under a particular workload. It's important because it helps identify bottlenecks and ensures that the application can handle expected user loads.

What are the different types of performance testing?

The main types of performance testing include load testing, stress testing, endurance testing, spike testing, and volume testing. Each type serves a different purpose in evaluating system performance.

How do you conduct performance testing?

To conduct performance testing, you typically define performance criteria, create test scenarios, use performance testing tools to simulate user load, and analyze the results to identify any performance issues.

What tools are commonly used for performance testing?

Common tools for performance testing include Apache JMeter, LoadRunner, Gatling, and NeoLoad. These tools help simulate user traffic and measure system performance.
