Good reporting and interface, but supports limited types of protocols and requires low-level script editing
It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

Performance testing has supported web app peak analysis but needs better setup and smarter scripting
Regarding points for improvement for OpenText Enterprise Performance Engineering (LoadRunner Enterprise), I see that features are not being fully developed yet. If OpenText could think about bringing AI features into the tool, it could save maximum time in scripting or make scripting effortless, particularly in correlation, which is where the complexity involved in script development exists. If any AI features could replace or eliminate more manual work on the correlation part, that is where we could see a game-changing improvement for the tool. OpenText Enterprise Performance Engineering (LoadRunner Enterprise) can be positioned very well in the market. However, I see that the basic correlations are only being handled by the autocorrelation engine in the LoadRunner tool, and I would expect a few improvements to handle even complex correlation problems so that the tool can be appropriately positioned compared to their peers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"All IBM testing tools are really well integrated."
"Using service virtualization, we are able to accelerate the testing and development activity."
"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."
"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"Support is nice, quick, and responsive."
"You can test a huge variety of applications, not just web-based systems, but SAP, Oracle, web services, pretty much anything out in the market place, but it's mobile-based testing."
"The most valuable feature is the Vuser protocols."
"The analytics and reporting features provide beneficial impacts on my organization, and the scalable testing environment is very beneficial for my performance testing processes."
"It helps us to be confident and to be aware of where issues are before we release a product to a wider audience."
"With Performance Center, the version upgrade is easy. You just have to roll out the new patch or the new version."
"For API testing, LoadRunner, getting the script developed in LoadRunner is very straightforward."
"What I like most in Micro Focus LoadRunner Enterprise is the comparison between two different exhibitions which gives value to my company. I also like that the solution is user-friendly, especially in terms of making specific changes. For example, in the past, you can't see the changes when you upload scripts into the Performance Center, but now, it has that visibility, so whenever you want, you can change the script in the Performance Center. I also like that Micro Focus LoadRunner Enterprise is the only tool you can utilize for all your needs, even for different protocols and scripting. The solution also has the latest features, for example, networkability, where it can, within the UI, follow the waterfall model. You can use the insights in the Performance Center of Micro Focus LoadRunner Enterprise to address or test URLs that usually take up much time."
 

Cons

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there."
"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."
"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."
"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."
"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."
"Almost all the areas improve drastically with each version; however, the correlation of scripts, analysis and reporting can be further improved. Their technical support could also be improved."
"Why they use other tools, that's where I would say there's some poly-functionality that has to be improved in the product."
"I believe the data that demonstrates the automated correlations should be corrected."
"I'd rate the scalability a six out of ten. The main reason is that it's a very expensive application. Other companies might not be able to afford it. For example, if we need to test an application with 10,000 concurrent users, the license can cost a lot of money. That's where OpenText tools shoot themselves in the foot compared to other tools. Because of the price, many companies, like one I used to work for, decided not to renew their licenses and switched to open-source testing tools."
"The solution is expensive."
"The solution is a very expensive tool when compared with other tools."
"Deletion of collating test results by admin access only."
"The migration from LoadRunner to Performance Center was not as smooth as I would have liked."
 

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."
"It doesn't really concern me. Licensing is on a yearly basis."
"This solution can be expensive."
"I give the cost a one out of ten."
"We purchased the license via SAP."
"We used the Professional version and then moved to the enterprise version. We have subscribed to 1000 user licenses. The tool will be super expensive if we take up 5,000 user licenses. We have to limit ourselves on testing."
"The solution should decrease its price."
"There is an ROI. What LoadRunner does, is it prevents failures when there are many, many concurrent users in the systems of a company."
"The price is a bit too high."
"LoadRunner Enterprise's price is high."
