What is Load Testing?
Definition of load testing
The definition of load testing, according to Wikipedia is:
“Load testing is the process of putting demand on a system or device and measuring its response. Load testing is performed to determine a system’s behavior under both normal and anticipated peak load conditions. It helps to identify the maximum operating capacity of an application as well as any bottlenecks and determine which element is causing degradation.”
Difference between load testing and stress testing
The difference between stress testing and load testing is that stress testing focuses on how the website or system can be broken and load testing concentrates on how much volume the website or system can handle. Both of these aspects can be absolutely vital for a website to function properly once visitor levels start to increase. If your peak season is the runup to Christmas and the number of users rises dramatically during this time in order to purchase items only to find that the website has fallen over due to the increased load then this could affect your entire Christmas season.
