What is Performance Testing?
Performance testing is a type of software testing that aims to determine how a system performs under various conditions, such as a large number of users, high traffic, or extreme data volumes. It helps identify bottlenecks, measure response times, and evaluate the overall scalability and reliability of the system. By simulating real-world scenarios, performance testing enables teams to optimize their applications, ensuring they can handle expected workloads and provide a seamless user experience.
Main Goals of Performance Testing
The primary objectives of performance testing include:
- Identifying performance bottlenecks and areas for improvement
- Evaluating the system’s scalability and reliability
- Measuring response times and throughput
- Ensuring the system can handle expected workloads
