Hello Friends,
In My company i am work on manual testing. My question Is it possible to check or calculate performance testing manual OR Performance testing check
only by automation.

Hi Bhushan,

It is definitely possible to do Performance testing Manually but the percentage of Companies / People doing so would really be negligible since Performance testing tools have come into the fore.

The disadvantage of doing Perf testing manually would be you would never be able to simulate the exact load at the given instance. Reason being users operating manually would differ in their working speeds, synchronization etc. Also we would require as many number of machine where AUT would be deployed.

We could measure Page Download time, Response times, Memory usage, Disk Usage etc manually. Perfmon is an windows inbuilt monitoring tool to measure various performance metrics.

Perf testing using Automation tools like QTP is definitely possible and is being carried out by companies who cannot afford licenses of tools like LoadRunner.

Using QTP we could record functionality and play back the same at differnet machines to simulate simultaneous load. You can also playback QTP scripts using Termimal emulator to create more Vusers per script.

A better option would be to procure tools like LoadRunner or Open Source tools like OpenSTA.

Cheers.....

Hi V.Umesh Krishnan,
It is very good explaination. Thank you to Replay.

what r the baseline documents for performance testing

hi umesh

As you said "We could measure Page Download time, Response times, Memory usage, Disk Usage etc manually. Perfmon is an windows inbuilt monitoring tool to measure various performance metrics."

Will you please let me know

step by step proceudre to measure Page Download time, respnse time,meory usage, Disk usage

I am waiting for your reply umesh

Thanks

hi vajragirtha,

"what r the baseline documents for performance testing"

As per my view did you mean performance, subsystems,interfaces,components in and out scope for this test

Thanks

Hi Deepa,

Well your question brought me out of exile after a long time...

With regards to using Perfmon to measure performance statistics, as explained earlier it is a windows inbuilt tool.

You can ascertain certain performance counters related to the machine where the test application is being run. Counters would be in terms of -
Pages / Sec in terms of Memory used, Avg Disk Queue Length in terms of Physical Disk, % Processor Time used in terms of CPU utilization.

Go to Run - type perfmon and click ok. You would find the Performance window open up. You would find all the mentioned counters listed under System Monitor.

By Default monitoring happens only for the system on which test application is running or where Perfmon command is executed. Incase you have a lan where other machines are connected and you have administrative rights on those as well, you could measure the required counters on those machines also.

Go to Performance Logs and Alerts in Perfmon - Right click on Alerts and select New Alert Settings. Once you name the alert, Click on Add... A list of counters would be displayed and you would find a drop-down indicating the machine where it is being measured.

Select the required machine, Select the required Performance Object and select the desired counters. Click on Explain and you can understand what each counter signifies. You can also set threshold limits for each counter. You can specify the action to be taken incase of an alert and also schedule the performance monitoring to be done for a specific time.

Hope this gives a bit of insight into Performance monitoring....

Cheers...
Umesh

hi umesh,

I have opened two applications but nothing can be viewed undersystem monitor why???
I am waiting or your reply
