The purpose of performance testing is to evaluate the speed of the software under various conditions. To elaborate, it mainly looks at the system’s overall responsiveness, stability, resource consumption, and even scalability.
Performance Testing
As with acceptance testing, performance testing should also be divided into sub-types
- Load Testing: This is a process by which the system’s behavior is checked as normal load increases.
- Stress Testing: Evaluate the robustness of a system under peak loads.
- Spike Testing: Creates a large spike in user load by simulating sudden changes.
- Endurance Testing: Verifies the performance of the system over prolonged periods.
- Scalability Testing: Examines how well the application performs as data volumes increase.
Testers can identify possible breaking points in the software and check that the software can handle the expected load during production through these sub-tests.
This sub-test assists in finding bottlenecks, memory leaks, or software defects that can result in slow response times or system failures.
