Performance testing is one of the tools of quality assurance which is used in order to understand whether the software withstands different loads in the context of the response and whether it remains stable.
This type of testing is extremely important because it estimates the product safety.
Some experts believe that errors detection in the functional is the main purpose of performance testing, but this opinion is mistakable. The real aim of this methodology – the determination of the elements which limit the performance of the system.
During this type of testing, the testers should focus their attention on what number of simultaneous users can be withstood by the system (without loss of productivity) and how fast it responds to the different manipulations.
Performance testing is a rather wide field of activity as it possesses not one but several main focuses: scalability, stability, work speed. Mobile application testing and web application testing should include at least several performance testing components because, at any race, one of them should reduce the risk of disorderly close-down during the multi-platform usage.
Performance Testing Parts:
- Stress testing – the checking of the software response to the critical loads.
- Reliability testing – the time intervals determination during which the system can withstand loads of the optimum performance.
- Load testing – the estimation of the maximum number of users and load which the product can carry without program abort or the fault.
- Volume testing – the detection of maximum user amount which the system can withstand simultaneously at no cost in its productivity.
Performance testing procedures are extremely important, as they are directed to the satisfaction of the clients’ and users’ expectations relatively the software strength.
