Q: Does reliability testing take place during load testing?
A:
Yes and no.
Yes, because the term, load testing, is often used synonymously with
stress testing, performance testing, reliability testing, and volume testing.
Because load testing is a blanket term that is used in many different ways across
the professional software testing community.
No, because load testing and reliability testing are somewhat different.
By definition, reliability testing is testing the system/software, to determine whether it meets
the specified reliability requirements. And, by definition, load testing is testing an application under
heavy loads, such as the testing of a web site under a range of loads to determine at what point the system
response time will degrade or fail. Load testing simulates the expected usage of a software program,
by simulating multiple users that access the program's services concurrently.
Load testing is most useful and most relevant for multi-user systems, client/server models, including web servers. For example, the load placed on the system is increased above normal usage patterns, in order to test the system's response at peak loads.
