By measuring performance and identifying bottlenecks, we have reduced costs, minimized testing and deployment times
My company needed a better way to introduce new applications and update existing software releases efficiently. Our past system hindered us from delivering new products and services quickly. To maintain rapid business growth, we realized that seeing the entire IT process during such projects was essential. We required appropriate testing tools to assess processes, manage change, determine application performance, resolve problems and improve defect visibility.
We wanted to move away from simply dealing with defect management and introduce a new testing regime with a sound methodology. We needed well designed testing processes, the correct software tools to support requests and a quality platform for test management and release. My company researched the market and approached several software specialists including HP. To evaluate proposed solutions, we presented each vendor with several testing scenarios. We liked the adaptability, ease-of-use and reporting capabilities of the HP Software solution.
The HP solution comprises a comprehensive package of software tools to help us reduce risk, lower cost and increase real-time visibility – key business drivers within the financial services industry. HP QuickTest Professional offers us automated functional and regression testing to lower the time, risk and cost associated with application testing, whilst HP Project and Portfolio Management Center provides real-time visibility and control over IT projects that are important to our business strategy.
To decrease problem resolution times, we deployed HP Service Manager 7, a comprehensive and fully integrated IT Service Desk suite containing seven foundation components, a Help Desk and a Change Management module. Moreover, HP Quality Center, a web-based application, accelerated the application lifecycle by presenting consistent, repeatable processes for planning tests, analyzing results and managing defects.
In addition, before we introduce a new application or upgrade a release, we utilize HP LoadRunner to detect potential performance problems within the production environment. By measuring end-to-end performance along with identifying application and system bottlenecks, we have reduced costs by 31 per cent and minimized application testing and deployment times.
With the introduction of the HP Software solution, the analysts and developers in our IT department have witnessed a transformation of the company’s testing methodology. We now have a comprehensive testing environment which previously lacked scope. Quality management, quality assurance and defect management have improved significantly, and application performance issues are readily resolved.
We estimate that IT efficiency has improved 24 percent. A recent return on investment study looking into the deployment of HP Quality Center indicates that over the last three years we have saved approximately $6.75 million. Moreover, annual quality management process efficiency estimates stand at $1.26 million and the annual financial benefit of avoiding application support costs is at least $820,000. With this dynamic HP solution, the number of defects resolved over a three day period increased to 44 per cent and problem resolution times have fallen by 60 per cent.

Valuable Features
The feature I find most valuable is the ability to find performance issues before putting a new application live.
Improvements to My Organization
LoadRunner is the standard choice for performance testing before any critical applications are allowed to go live, preventing any performance issues.
Room for Improvement
LoadRunner is a well-rounded, polished tool – but it does need more improvement when it comes to it application of load, more flexibility mid-test would be nice.

Customer Service and Technical Support
Customer Service: The Customer Service is good, the sales guys are not overly aggressive to sell, as the product does sell itself.Technical Support: The Technical Support is OK. It’s not as good as the Pre-HP acquisition days at Mercury.
Initial Setup
LoadRunner runs an automated install which is quite simple.
Implementation Team
LoadRunner was installed in house.
Other Advice
Research your strategic requirements. Think long term, it WILL work out cheaper. LoadRunner is not a tactical solution.

Architect at a healthcare company with 501-1,000 employees
Excellent load testing capabilities & reports. Quick visibility focusing in on a problem area is extremely helpful.
The main reason that we decided to implement LoadRunner was because of our serious lack of insight into exactly where flaws were stemming from when a problem arose or how we could fix those problems earlier and more efficiently in the future. When a problem was found, solutions could only be given after the fact, making the losses bigger and causing more damage than necessary. We needed to increase our awareness of the challenges and issues that could come up before they arose, or at least catch the problems faster than we currently were, in order to tackle them properly.
As the company grew and our infrastructure increased, the task of testing and debugging our entire system transformed into a colossal and costly problem. Our service, which includes providing healthcare and insurance services to a wide range of patients and clients, was becoming inefficient as well, making the need for in-house testing of our various software flaws urgent.
LoadRunner seemed to be an obvious solution since it recreates real life scenarios on a virtual plane in order to test the performance rate, speed, efficacy and functionality of the system during those actual situations. In this way, we could easily pinpoint problem areas, bugs and other flaws to the system prior to the real time launch, avoiding tremendous issues from ever arising.
We tried out three different virtual assessment products concurrently. Each of these products was tested in a wide range of areas that were either commonly known to be problem areas or were considered to be of great importance to remain problem-free. Some included:
- Secure systems
- Overall system substructure
- Performance speed and accuracy
The system that came out as superior during the testing was HP LoadRunner, and we purchased the package immediately upon reviewing the results of the trials. This choice was made primarily for the software’s extensive capabilities, though HP’s greater overall presence within the technology field also contributed to the ultimate decision.
Installing LoadRunner was an uncomplicated procedure, needing no third party or outsourced services or tools. The successful implementation of this software led to the acquisition of some 250 licenses from the onset and an additional 1500 in subsequent months.
We proposed a three-year window to view the results and overall ROI of the product. To our surprise, LoadRunner provided positive effects even faster than we would have expected in a real and tangible example as described below:
One of the portals that our company used for selling various insurance packages and products developed major issues. As a result, brokers were losing sales because of the inaccessibility of their services. With the use of HP LoadRunner, the entire issue was simulated, examined and solved within a week of the initial symptoms. The software actually paid for itself within that first month simply due to the efficient manner in which the problem was able to be recreated, analyzed and dealt with.
Other members of the staff also found the product to be more effective and easier to work with due to the alacrity and smooth, automatic functions that were performed. As a result of these faster protocols, team members were able to meet strict deadlines that were otherwise unrealistic prior to theLoadRunner implementation.
The load testing capabilities and efficient performance were rated as the most integral aspects of this software, though the adeptness at getting to the core of the issue was a very close second.
Other features that people found generally helpful were the reports and the quick visibility focusing in on a problem area. Using HP LoadRunner in combination with the SiteScope software from HP has made all of these inevitable mishaps easier to deal with in a timely manner.
Our use of LoadRunner has become a standardized process, a part of our regular routine. The software is repeatedly used to discover the source of a problem when code freezes pop up. What is more, the usage of these tools is not limited to IT techs; everyone from the developers to quality assurance and even management is actively using this software to hone in on the problem areas and solve the issues quickly.
HP LoadRunner has been a gateway into the implementation of other invaluable HP tools such as Application Lifecycle Management products. In general, there has been a vast improvement to the performance and output of the company since the use of this product has been initiated, and everyone has seen positive results in the form of fewer problems, greater visibility and faster response times to issues that will come through. Having a central database for problem solving tools and resources has also contributed to the efficacy of our staff individually and as a team.

What’s new in LoadRunner 11.52 ?
On 12th June at HP Discover, I attended one of lecture sessions led by Shane Evans and Silvia Siquiera. During the presentation, they introduced the new features of LoadRunner 11.52. They started the presentation by introducing the new features that came in LoadRunner 11.50 (last year) and then highlighted the features that had been added since then.
Key new features:
- Improved application performance (particularly VuGen startup and Analysis).
- Integration with HP Live network. (HP Live network connects partners customers etc.)
- Replay summary report displays detailed statistics.
- Improved run time settings interface.
- Can now configure round robin ramp up across load generators.
- Integration with Visual studio and eclipse for agile CI/CD.
- Support for Junit, nUnit and Selenium in LR scenarios.
- LR scenarios as part of unit testing.
- Can add performance tests as build steps in Jenkins.
- VTS 2 is a big feature.
- Mobile traffic recording apps for Android.*
- New, improved proxy recording feature.
- Shunra network virtualisation enhancements, a single load generator can now simulate different network types simultaneously e.g. some users on 3G, others on DSL etc. this removes the requirement to have a load generator for each “network type”.
- Additional support for Linux load generators (different Linux versions).
(This alone could be a reason to migrate to 11.52, Linux load generators can significantly reduce license costs for your test equipment).
*Whilst the new mobile recording engine is useful, I can’t help but feel that HP has scored an “own goal” in marketing terms. A number of their competitors are making lots of noise about their ability to test mobile applications and this announcement implies that HP are only just getting their act together on mobile testing. HP has been able to test mobile (and many other) applications via a proxy recorder for as long as I can remember and I’ve been using LoadRunner since 1999. This is new proxy recording engine undoubtedly makes scripting easier but it isn’t their first foray into mobile testing and their competitors are disingenuous if they try to make that claim.
Future trends
64-bit VuGen
One customer asked about whether HP had any plans for 64-bit VuGen or
Load Generators. Shane Evans said that they didn’t perceive particular
demand for this especially since load generators could each spawn
multiple 2GB processes for load generation but that they would consider
this if there was sufficient customer demand.
This question prompted a few others and one customer asked whether dcripting languages other than C were being considered. Shane said that JavaScript was being considered as a possible scripting language. This could pave the way towards using NoJS as a test engine.
Network simulation
The discussion then moved to network simulation and Shane asked the room
whether people were using network simulation tools like Shunra or WANEM
as part of their tests. Only 2 people in an audience of approximately
90 were using network simulation tools.
Diagnostics tools
Only one customer was using HP diagnostics and two or three others were
using Dynatrace or other diagnostics/profiling tools like Wily
Introscope. I would be very surprised if network simulation and
application diagnostics weren’t significant growth areas for specialist
testers in the coming years. These products add significant value to
testing engagements and are becoming more important as users become more
mobile and applications are increasingly hosted on virtual platforms
where performance optimisation is more important.
VTS2 – Virtual Table Server
Shane then did a small demonstration of VTS2. I was a big advocate of
the original VTS (virtual table server) and since it’s demise I’ve
looked at various ways of managing test data in scripts (such as
using MySQL)
. VTS was always an unsupported add-on (originally written by Mercury
engineers) to allow parameters to be passed from script to script. This
worked well but had a number of limitations. As well as being
“technically” unsupported, the database had to be loaded with parameters
from a CSV file before tests and you had to remember to save the
“database” to a file each time that you shut it down.
VTS2 doesn’t have these limitations. It is based on the MongoNoSQL database and can handle up to 2000 txns/sec easily (I can’t wait to try this properly). Media for VTS2 comes with LoadRunner 11.52 or is downloadable from HP SSO.
LoadRunner 12.0 ?
Silvia mentioned the fact that there were so many new features, some
people within HP felt that this could merit a new major version number
rather than simply adding 0.02 to the last release. This reminded me of
Stuart Moncrieff’s summary of 11.50 last
year. Having seen the new features, I think that she’s probably right,
LoadRunner 12.0 and Performance Center 12.0 are probably already here :)

True Client Ajax is quite effective for simple Http based Web applications. It saves lots of scripting time. Script modification is also quite easy.
But True Client has few constraints, I may effect the test results as it consumes quite an amount of memory per vuser instance. So an injector may support X no. of users for WebHttp protocol, but it may not support the same for Ajax True Client.
Ajax True Client is good protocol to use, but with few constraints.
