  4. What is Performance Testing? • Performance Testing is a process of testing a software application under a specific workload

  5. What is Performance Testing? • Performance Testing is a process of testing a software application under a specific workload • Testing is performed to test the speed, reliability, response time, and resource usage

  6. What is Performance Testing? • Performance Testing is a process of testing a software application under a specific workload • Testing is performed to test the speed, reliability, response time, and resource usage • The focus is on identifying and eliminating any resistances in the software application

  7. What is Performance Testing? Speed Scalability Stability

  8. Why Performance Testing?

  9. Why Performance Testing?

  10. Why Performance Testing? • The goal here is to eliminate performance glitches rather than finding bugs

  11. Why Performance Testing? • The goal here is to eliminate performance glitches rather than finding bugs • Performance testing enables stakeholders to have an idea about the application stability, scalability, speed

  12. Why Performance Testing? • The goal here is to eliminate performance glitches rather than finding bugs • Performance testing enables stakeholders to have an idea about the application stability, scalability, speed • The testing brings forward the issues that must be fixed before the application reaches the market

  13. Types of Performance Testing?

  14. Types of Performance Testing?

  15. Types of Performance Testing? Load Testing Stress Testing Volume Testing Capacity Testing Reliability Testing Scalability Testing

  16. Types of Performance Testing? Load Testing Load Testing Stress Testing Volume Testing • Load testing is a type in which an application is tested for its performance at normal and peak usage • The performance is checked per the response time and consistency on different user loads Capacity Testing Reliability Testing Scalability Testing

  17. Types of Performance Testing? Stress Testing Load Testing Stress Testing Volume Testing • Stress testing is a type in which different ways to break the system are found, i.e., how much load a system can sustain • It checks how much load a system can hold in an incremental approach Capacity Testing Reliability Testing Scalability Testing

  18. Types of Performance Testing? Volume Testing Load Testing Stress Testing Volume Testing • Volume testing is a type where the performance of the system is checked with respect to the volume of data • To perform the test, a huge amount of data is entered into the database Capacity Testing Reliability Testing Scalability Testing

  19. Types of Performance Testing? Capacity Testing Load Testing Stress Testing Volume Testing • Capacity testing is a type in which an application is checked for its capability to meet business volumes • The testing is performed keeping in mind the prospects of an application and the number of users Capacity Testing Reliability Testing Scalability Testing

  20. Types of Performance Testing? Reliability Testing Load Testing Stress Testing Volume Testing • Reliability testing is a type in which the application is verified if the application would become normal again after an abnormal state • It estimates the time that the system would take to return to its normal state Capacity Testing Reliability Testing Scalability Testing

  21. Types of Performance Testing? Scalability Testing Load Testing Stress Testing Volume Testing • Scalability testing is a type where the application is determined if it would be able to scale up whenever needed • The need for scaling up comes when there is an increase in user load Capacity Testing Reliability Testing Scalability Testing
