Performance Testing-Overview

What is Performance Testing :

Performance testing is a form of software testing that focuses on how a system running the system performs under a particular load.

Types of Performance Testing :

1. Load testing
2. Stress testing
3. Spike testing
4. Endurance testing
5. Scalability testing
6. Volume testing

Bottleneck Issues in Performance Testing :

1. Speed issues — slow responses and long load time
2. Poor scalability
3. Disk usage
4. CPU usage
5. Memory leaks
6. Operating system limitations
7. Poor network configuration
8. Software configuration issues
9. Insufficient hardware resources

Five common performance testing mistakes

1. Not enough time for testing.
2. Not involving developers.
3. Are not using a QA system similar to the production system.
4. Not sufficiently tuning software.
5. There is not a troubleshooting plan.
