Goals of load testing:

• expose bugs that do not surface in cursory testing, such as memory management bugs, memory leaks, buffer overflows, etc.

• ensure that the application meets the performance baseline established during performance testing. This is done by running regression tests against the application at a specified maximum load.

          Although performance testing and load testing can seem similar, their goals are different. On one hand, performance testing uses load testing techniques and tools for measurement and benchmarking purposes and uses various load levels. On the other hand, load testing operates at a predefined load level, usually the highest load that the system can accept while still functioning properly. Note that load testing does not aim to break the system by overwhelming it, but instead tries to keep the system constantly humming like a well-oiled machine.
