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

"Using service virtualization, we are able to accelerate the testing and development activity."
"All IBM testing tools are really well integrated."
"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."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"We have eliminated a lot of production issues because we are able to test so many virtual users at once."
"LoadRunner Enterprise's best feature is the detailed reporting structure."
"The most valuable feature is the analysis tool; it enables me to make a good, detailed analysis after a test run."
"It is also good for reporting purposes, which would be most familiar for QC and UFT users."
"From a technical perspective, LoadRunner has always been good."
"The product is good, and the concept is good as well."
"Now that LoadRunner integrates with Dynatrace and other monitoring tools, it simplifies the process of integration into a company, taking merely five minutes to set up. This ease of integration allows for quick comparison of monitoring and performance results, a feature I highly appreciate."
"The solution is a very user-friendly tool, especially when you compare it to a competitor like BlazeMeter."
 

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. 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 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."
"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."
"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."
"OpenText LoadRunner Enterprise doesn't support some mainframe protocols. We had to build scripts to access the interface."
"It's expensive, so could be cheaper."
"LoadRunner Enterprise's reporting should be quicker, easier, and more flexible."
"When we have a new application, recording the application is a pretty tough task. We have tried multiple things. We do scripting or try to record with different settings and on different machines. We try to record multiple times, but we do not know why it is recording and why it is not recording. We do the same thing on different machines. It sometimes records, and at other times, it does not. That is one of the major concerns."
"It was a bit complex in terms of administration but we got help from technical people."
"Some features could sometimes disappear without reason."
"The technical support offered by the product is an area of concern where improvements are required."
"More real-time monitoring should be available for the system under test."
 

Pricing and Cost Advice

"It doesn't really concern me. Licensing is on a yearly basis."
"The pricing is a little bit on the higher side, although it is really good."
"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."
"I give the cost a one out of ten."
"LoadRunner Enterprise's price is high."
"The price is really steep. It's an enterprise-level tool."
"The price is okay. You're able to buy it, as opposed to paying for a full year."
"The price of Micro Focus LoadRunner Enterprise could improve, it is expensive."
"It is a bit expensive, especially for smaller organizations, but over-all it can save you money."
"I have not been directly involved in price negotiations but my understanding is that while the cost is a little bit high, it provides good value for the money."
