What is the difference between stress, volume and load
testing?

Answer Posted / belal raslan

Performance is not a testing type, its a family that
include (stress, load and volume).

Stress: Is testing the behavior of the system (or usually a
specific functionality) under extra usage conditions for a
specific period of time. Example: How many search request
can Google site handle in 1 minute.

Load: Is testing the system capability (peak) to handle
over load. this is usually done by adding v.users using
automation tools. Example: How many user sessions can
Google site handle concurrently.

Volume: Is used with stress and load and its related to
testing the system for the 'exact' expected load and stress.
