What is Load Testing?
Load Testing evaluates how a system behaves when multiple users access it simultaneously. It helps identify performance bottlenecks and ensures the application can handle expected traffic.
Objectives of Load Testing
- Determine system performance under expected load
- Identify response time and throughput issues
- Ensure application stability during high usage
Advantages
- Prevents system crashes under heavy load
- Improves user experience by optimizing performance
- Helps in capacity planning
Limitations
- Requires realistic load simulation
- Time-consuming for large-scale applications
- May need special tools for accurate testing
Load Testing Process
- Define performance goals and expected load
- Design test scenarios and scripts
- Simulate load using tools or scripts
- Monitor performance metrics (CPU, memory, response time)
- Analyze results and optimize the system
️ Tools for Load Testing
- Apache JMeter
- LoadRunner
- Gatling
- BlazeMeter
Best Practices
- Simulate realistic user load
- Test peak load scenarios
- Monitor key performance metrics
- Document findings and optimize system
