IT Specialist, ITE at a government with 10,001+ employees

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.

Founder & Chief Executive Officer at a tech vendor with 11-50 employees

Ensures high performance and adaptability while providing room for improved analytics and support

The analytics and reporting features can be improved, though they are good enough. If you have expertise, you can manage with what is included. However, it could be much better, especially with modern AI capabilities. When considering areas for improvement in OpenText Enterprise Performance Engineering (LoadRunner Enterprise), there is a need for automated analysis and code-level support.

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."

"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."

"The solution supports a number of protocols."

"We have eliminated a lot of production issues because we are able to test so many virtual users at once."

"Previously, we had different physical machines for each controller, and then we shifted to Performance Center, which allows users to log into a single instance and manage all other controllers from there."

"It is pretty easy to do test execution and results analysis. When it comes to scenario settings, LoadRunner Enterprise has an extra edge over other testing tools in the industry. The scenario setup is easy, and in terms of execution, we have a clear idea of what is happening"

"Support is nice, quick, and responsive."

"The most beneficial features of the solution are flexibility and versatility in their performance."

"We implemented through the vendor, who used highly-skilled professionals."

"Our customers think of the following benefits as ROI of using HP Performance Center: Reducing downtime in operations phase that may come due to load on system by fixing or customizing their application to afford the maximum number of concurrent users they expect Prior knowledge of their system limitation and its break point, may let them take precautions steps at application server or network level to prohibit overload traffic that may crash their system."

Cons

"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."

"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."

"I know there are integrations with continuous testing. It's got tie-ins to some of the newer tools to allow continuous testing. I'd love to see us not have to customize it, but for it to be out of the box."

"Many of my customers have had to switch to different tools due to the cost of LoadRunner, despite its advantages, leading them to alternatives like JMeter and RPT."

"On the newer versions, I think the bleeding edge is still being worked on."

"Lacks the option of carrying out transaction comparisons."

"There are many issues that require day-to-day maintenance."

"Browser compatibility. IE is no longer the only browser out there, so providing users the choice of what browser to use would be great!"

"The TruClient protocol works well but it takes a lot of memory to run those tests, which is something that can be improved."

"It is tough to maintain from the infrastructure side."

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."

"The tool is very expensive."

"The prices would differ depending on the number of licenses you need. I wouldn't maybe compare it to any other tools. I rate the price as seven out of ten."

"This solution can be expensive."

"The price is really steep. It's an enterprise-level tool."

"The price of Micro Focus LoadRunner Enterprise could improve, it is expensive."

"I give the cost a one out of ten."

"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."

"We are content with the pricing and find it to be reasonable in terms of value for money."
