Increasing awareness and use of web as well as mobile applications brings a flood of various software
applications in the market. To achieve a target of potential users an application must fulfil the requirements such as its response time,speed, scalability, stability etc.
Performance testing is not just to find
the bugs in a software but in actual it is a task to eliminate the
performance bottlenecks.
Performance testing is a vast concept
that is not possible to explain here about software performance
testing so here we will discuss some basic concepts of software
performance testing with some details of performance testing
institutes in Noida & NCR region providing training in
the same domain.
As we have already discussed that
performance testing is a technique to analyse and improve the
performance of software or in other words performance testing
is a means of Quality Analysis (QA). Before launching an
application software must pass through a process of performance
testing.
The performance testing types involved
in the process are:-
1) Load Testing :- is done to
ensure the desired performance under specific workload or to maintain
the software performance in an increasing users environment.
2) Stress Testing :- is
performed to check the maximum capacity of the application to perform
well under an extreme load. Also this will helps an application
administrator to determine how long an application works sufficiently
above the expected load.
3) Soak Testing/Endurance Testing
:- is done to ensure that an application can handle an expected
workload over a long time period. During this memory utilization is
to be monitored to detect memory leaks.
4) Spike Testing :- is done to
check ability of system to handle workload. In this performance of
software application is measured by increasing the number of users
suddenly in a large amount.
5) Volume Testing :- the behaviour of application software is monitored by populating a large
number of data in database.
6) Configuration Testing :-
performance and the behaviour of the system is tested as system
configuration changes.
7) Isolation Testing :- In
Isolation testing the application is divided into various modules so
that defects can easily be find by the developers.
Factors affecting the performance of an
application :-
Long Load Time :- The initial
time taken by an application to start. It should be minimum up to few
seconds.
Poor Response Time :- Time taken
to execute and output a result after getting input. This also should
be quick as the users may lose their interest if they have to wait
for a long time.
Poor
Scalability :- The condition when the application get
failed to handle the expected number of users. So for this load
testing is to be done to handle an expected number of users.
Bottle-necking :- Bottle-necks
are the obstructions that will degrade the overall performance of the
system. Bottle-necks can be due to the coding errors or hardware
issues. This can be fixed either by upgrading hardware or by fixing
poor running processes.
This was a general information about
performance testing and the complete knowledge can be gained
by taking training from a professional software testing training
institute. One such good software performance testing training
institute is QACampus where training have been provided by the real
time software industry experts. The curriculum is designed in an
emphasized manner to meet the requirements and standards of the
software testing industry. The training is provided with
latest tools like Jmeter, Open STA, Load Runner, Web Load. After
successful completion of training one can be able to test the
performance of web as well as mobile application.
