Hi
Here are the Opinions of the some of the allinterview users
posted in previous on Scalability Testing..
1.scalabilty is nothing but how many users that the
application should handle
2.Scalability is nothing but maximum no of users that the
system can handle
3.Scalability testing is a subtype of performance test
where
performance requirements for response time, throughput,
and/or utilization are tested as load on the SUT is
increased over time.
4.
as a part of scalability testing we test the expandability
of the application.
in scalability we test 1.Applicaation scalability
2.Performance scalability
Application scalability: to test the possibility of
implementing new features in the system or updating the
existing features of the system. with the help of design
doc we do this testing
Performance scalability:
to test how the s/w perform when it is subjected to
varying loads to measure and to evaluate the the
performance behaviour and the ability fo the s/w to
continue to function properly under different workloads.
--> to check the comfort level of an application in terms
of user load. and user experience and system tolerance
levels
--> the point within an application that when subjected to
increasing workload begin to degrade in terms of end user
experience and system tolerance
--> response time
execution time
system resource utilization
network delays
--> stress testing
Thanks & Regards
