Performance Testing focuses on non-functional parameters of the software program. It allows to verify how the system and it components work regarding scalability, reliability, throughput, responsiveness, etc. under particular circumstances. This process is aimed at addressing specific problems associated with software architecture and design.
Goals of Performance Testing
The principal objective of performance testing is to define the behavioral pattern of the software system. Performance testing services do not help to find software defects, but to troubleshoot performance bottlenecks.
The process is carried out to test the standard set and benchmark for the software program. Performance testing is characterized primarily as close monitoring of the app’s performance and obtaining accurate results of the testing.
How Does Performance Testing Differ From Stress Testing & Load Testing?
Load Testing is carried out to know how the system is performing under anticipated load that is constantly and steadily increased. This approach helps to identify the product’s maximum operating capacity. The testing is the simplest verification process and can be performed with automation tools similar to LoadRunner. Load testing is also known as endurance testing and volume testing.
Load testing is aimed at detecting all the bugs in software that have to do with memory leaks, memory mismanagement and buffer overflow. Delivering load testing service, the specialists also tend to determine the load limits of all app’s components such as hardware, database, network and others. The primary goal of the testing is to define how much work can be handled by the system without causing considerable performance degradation.
Stress Testing involves a variety of activities associated with applying excessive workloads to the existing resources with the purpose of breaking the system down. An integral part of stress testing is negative testing – the process wherein the components are removed from the system. The testing is referred to as fatigue testing that focuses on determining the application’s stability by testing it beyond the limits of its normal operational capacity.
Stress testing service is used to determine the extent to which software program keeps working when the extreme workload is applied to it or when some of its software or hardware have been compromised. The key purpose of the testing is to define the app’s behavior after failure and analyze post-failure reports.
