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

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"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."
"All IBM testing tools are really well integrated."
"Using service virtualization, we are able to accelerate the testing and development activity."
"With LoadRunner, 80% of the cases will be supported."
"The built-in feature of Performance Center that does this, has made allocation of resources much, much easier."
"With Performance Center, the version upgrade is easy. You just have to roll out the new patch or the new version."
"Customer service is excellent."
"​Probably its prime advantage, it provides a centralized location for testing."
"What we call the LoadRunner analysis is the most useful aspect of the solution."
"With the latest updates, it is very comprehensive and one of the best products of the sort."
"LoadRunner Enterprise's best feature is the detailed reporting structure."
 

Cons

"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."
"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."
"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."
"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."
"When you initially file a support case, it's difficult because they ask you many technical question to assess the problem."
"They had wanted to change the GUI to improve the look and feel. However, since that time, we see a lot of hanging issues."
"The migration from LoadRunner to Performance Center was not as smooth as I would have liked."
"It would be beneficial if LoadRunner could optimize resource usage, especially for protocols that require significant resources, like TrueClient, which interacts directly with the UI. If they could improve resource usage, like ingest or for the load generator, using less CPU or RAM memory, that would be great. That's where I have problems."
"Why they use other tools, that's where I would say there's some poly-functionality that has to be improved in the product."
"Running virtual users especially with a huge number is a very challenging task. The load generators may over utilize its resources (CPU/ memory) due to improper default configurations, or improper use of LoadRunner and Performance Center."
"Unfortunately, technical support is not as good as it used to be. From an end-user perspective, coming from both me and several of my team members, we have found that over the last year and a half, the quality of support has gone down a couple of notches."
"It would be good if we could look forward at the future technology needs we have. I would like to see Micro Focus provide more customer awareness around how LoadRunner can fulfill requirements with Big Data use cases, for example, where you do performance testing at the scale of data lakes... when it comes to technologies our company has yet to adopt, I would like to see an indication from Micro Focus of how one does performance testing and what kinds of challenges can we foresee. Those kinds of studies would really help us."
 

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."
"I rate the product's pricing a three out of ten."
"The price is really steep. It's an enterprise-level tool."
"The price of Micro Focus LoadRunner Enterprise could improve, it is expensive."
"The tool is very expensive."
"The price is a bit too high."
"It is a bit expensive, especially for smaller organizations, but over-all it can save you money."
"For Performance Center, you have to add additional load generators, and then you can do more. I think it is a matter of the price, in terms of how many machines you can buy."
"This solution can be expensive."
