Web Application Load, Stress and Performance Testing Using WAPT

Why most of the manual testers fail when testing websites for performance? There are couple of reasons.
They don’t have proper tools to test website for performance and
They don’t have required skills for performance testing.

Does that mean you should wait till your stakeholder report the performance glitches in web application you developed? Definitely not. Many testers are good at testing websites manually and they report almost every defect while testing under standard tests. BUT, when same tester performs load or stress tests they stuck either at resource (required tools) or skill level.

I suggest not to take any risk if you are committed to defect free service. Ask for required tools and train your staff for necessary skills. Today, I’m going to review load, stress and performance testing tool for websites. The tool is called WAPT – Web Application Load, Stress and Performance Testing – a cost effective and easy to learn web load testing tool.

WAPT allows you to perform website load and performance testing by creating heavy load from a single or multiple workstations. When you set and run your tests with this tool within a matter of minutes you can get performance report of your website or web application. WAPT uses powerful virtual users same as the real world users with full control over how to customize these virtual users.

Measuring website performance:

Did you ever wonder?
– How many users can work simultaneously on your website with acceptable quality of service?
– How many visitors your website can handle by day or hour?
– What is your website response time under load?

These all questions are nothing but the measure of website “performance characteristic”.

Getting Started With WAPT:


WAPT – website performance tool performs test by emulating activity of many virtual users. Each virtual user can have its own profile settings. You can have thousands of virtual users acting simultaneously on your website performing any activity like reading or writing with your web server. Once you set number of virtual users to act on your website you have option to run your tests for specified time or specified user sessions.

Analyzing the test report:
Test result consists of charts updated in real time which you can monitor when your tests are running. The final comprehensive report is provided at the end of the tests.

Here are the important parameters to be monitored on the test report:
Error Rate: Failure rate against total number of tests run. The error may be due to the high load on server or due to the network problems and timeouts.

Response Time: Obviously a great parameter to check when you run tests for website performance. This response time indicates time required by server to provide correct reply to the request.

Number of pages per second:
Number of page requests successfully completed by server per second.
How to conclude performance tests?
These performance criteria change during each test-pass with different load conditions. You need to conclude what is your acceptable load limit and whether your server is able to serve this load.

------------

E.g.: If you expect your server to handle 100 requests successfully per second then anything below this will be failure of your server which needs to be tackled.

How to Record tests:

WAPT works like any other record and playback tool but the real strength is behind it’s parametrization where you can configure any parameter from website url or user session to act as a real user.

Testing with WAPT in simple 5 steps:

Record->Configure->Verify->Execute->Analyze

WAPT uses inline Microsoft internet explorer which is used to record your interaction with website. When you record your test all dynamic parameters are recorded as static values which can be configured later while test execution. You then need to configure each user with different settings like unique sessions, number of virtual users, values for dynamic parameters etc. Once you done with recording and configuration just verify your test if it’s ready to run and then execute performance tests if everything looks ok. Finally analyze reports to decide website performance test as accepted or failed against your set of defined standards. That’s it.

WAPT is available in two versions
– Standard version (Latest WAPT 7.1)
– Professional version of this stress and performance testing tool (Latest WAPT Pro 2.1)

What WAPT Pro can do for you?
– Use several computers to generate load on website
– Measure web server performance in terms of CPU, RAM or network usage
– You can include the execution of a JavaScript code into virtual user profiles.

If you don’t want to specify every parameter manually you can use some technology specific modules to significantly improve your test experience.

Following additional modules can be downloaded and installed along with standard or professional version of WAPT:
– Module for ASP.NET testing
– Module for Adobe Flash testing
– Module for JSON format

Finally, any review can’t be complete without the list of Pros and cons.

WAPT Pros:

– Easy to install – Takes only 5 minutes to install
– Easy to use with very short learning curve
– You get run-time reports so that you can decide whether to continue the test or not, saving your big time.
– Detailed test report with graphical representation.
– Supports secure HTTPS protocol.
– 30 days free trial available!

WAPT Cons:

– Only windows platform supported to install this tool. (But you can test your website running under any OS and technology)
– No scripting ability
– It’s not free ;-)

How to try this tool?
You can download 30 day trial version of WAPT from here.

That being said WAPT makes website load, stress and performance testing super easy.

Over to You!

Excellent.
I faced similar problem recently. We didn’t have any formal training for performance testing but assigned to a performance testing task. I tried my best but still missed one important issue and that too reported by client :(
while doing performanc testing u must be aggressive in different testes and comparing the outputs.

good luck.
