When do you do load and performance Testing?

Answer Posted / mahesh sv

We perform load testing once we are done with interface
(GUI) testing. Modern system architectures are large and
complex. Whereas single user testing primarily on
functionality and user interface of a system component,
application testing focuses on performance and reliability
of an entire system. For example, a typical
application-testing scenario might depict 1000 users logging
in simultaneously to a system. This gives rise to issues
such as what is the response time of the system, does it
crash, will it go with different software applications and
platforms, can it hold so many hundreds and thousands of
users, etc. This is when we set do load and performance testing.
