📖 Overview

What is Stress Testing?

Stress Testing is performed to determine the system's robustness and error-handling capacity under heavy load or adverse conditions. It helps identify the breaking point of the system.

🔑 Key Aspects

🎯 Objectives

  • Check system stability under peak load
  • Identify breaking points and recovery ability
  • Ensure system does not crash unexpectedly

✅ Advantages

  • Helps identify system limits
  • Ensures reliability under extreme conditions
  • Improves system scalability and robustness

⚠️ Limitations

  • Requires high resource setup for testing
  • May be time-consuming to simulate real-world stress
  • Can be costly for large applications
📋 Process

Stress Testing Process

  • Define stress scenarios and objectives
  • Identify system's critical modules
  • Simulate extreme load conditions
  • Monitor system performance and failures
  • Analyze results and improve stability
🌍 Example

Real-world Example

Example: A banking website is tested with 10x more users than expected during a high-traffic event (like salary credit day) to check if the system can handle the pressure without crashing.

🏆 Best Practices

Best Practices for Stress Testing

Plan scenarios close to real-world peak loads

Use monitoring tools to capture performance data

Gradually increase load before applying extreme stress

Document recovery strategies after failure
