Computers Programming Software Testing Load and Performance Testing
28
Load testing is the act of testing a system under load. In software engineering it generally refers to the practice of modeling the expected usage of a program by simulating multiple users accessing the program's services concurrently. As such, this testing is most relevant for multi-user systems, often one built using a client/server model, such as web servers. However, other types of software systems can be load-tested also. For example, a word processor or graphics editor can be forced to read an extremely large document; or a financial package can be forced to generate a report based on several years' worth of data. When the load placed on the system is raised beyond normal usage patterns, in order to test the system's response at unusually high or peak loads, it is known as stress testing. The load is usually so great that error conditions are the expected result, although there is a gray area between the two domains and no clear boundary exists when an activity ceases to be a load test and becomes a stress test. There is little agreement on what the specific goals of load testing are. The term is often used synonymously with performance testing, reliability testing, and volume testing.
