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.

Centralized cloud testing has improved global load generation and real-time performance insights

The most valuable features I have found in OpenText Core Performance Engineering (LoadRunner Cloud) are that everything is online and centralized, so I do not need to go anywhere to check the configuration and everything. OpenText Core Performance Engineering (LoadRunner Cloud)'s advanced analytics help identify performance bottlenecks because whenever we are executing the test scripts, it shows a good analytics view where we can simply check which APIs are not performing well. The cloud-based load generators in OpenText Core Performance Engineering (LoadRunner Cloud) have benefited my testing setup because we can generate the load across the globe, which was previously a little bit difficult on the on-premises version. The user interface in OpenText Core Performance Engineering (LoadRunner Cloud) is intuitive and this will be easy to communicate and collaborate amongst the team also because sharing the online URL with the team, they can simply check the analysis and everything.

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."

"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."

"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."

"It's fast, easy to use, has a user-friendly UI, and you can split users."

"The usability and ability to integrate with other solutions is quite good. When I use it in on Azure, then Red Hat is the most likely solution I use. When I use AWS, then I tend to use Lambda functions. In either case, it works well and you can use it either way."

"The product’s most valuable feature is the Vuser license; it allows us to reduce the cost as per requirement."

"One of LoadRunner's standout features is its extensive support for various TechStacks and protocols."

"Both the professional and cloud versions of Micro Focus LoadRunner use the same scripting or programming to execute performance modeling operations. This feature allows users to use various programming languages such as Java, C, or C++, which can run within either of the two environments. This flexibility in the programming language is a strong point of the software."

"The TCO has been optimized along with the total ROI."

"I rate OpenText LoadRunner Cloud ten out of ten."

"HP StormRunner Load has provided us flexibility for on demand load generation, reduced overall TCO on our load testing efforts, and reduced the skill level to develop load test scripts."

Cons

"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."

"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."

"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."

"In terms of new features, they can natively integrate with Chaos engineering tools such as Chaos Monkey and AWS FIS. With LoadRunner, we can generate load, and if Chaos tools are also supported natively, it will help to get everything together."

"StormRunner is very rudimentary at this time, but it's a great concept."

"I have faced several problems using the cloud in different locations, so I rate the stability a six out of ten."

"One area of improvement in the software's support is the replaying of captured data within the development environment. It would be beneficial if the replay feature could accurately mimic what the actual application is doing for better analysis and testing."

"Their documentation is not technical enough for us. We would like to have much deeper technical documentation so that we can self-serve without constantly having to go back to them and ask."

"Regarding improvements in OpenText Core Performance Engineering (LoadRunner Cloud), the initial configuration where we have to set up orchestration is something that could be improved."

"Sometimes, you are utilizing one of the low generators, then all of a sudden if you discontinue from one project, it actually deletes the entire low generator."

"I don't know of any features that should be added. The solution isn't lacking anything at this point."

More OpenText Core Performance Engineering (LoadRunner Cloud) cons

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."

"It is expensive compared to other tools."

"The pricing for OpenText LoadRunner Cloud is average."

"LoadRunner always had expensive pricing. At my company, we used to evaluate LoadRunner, but we stuck with Silk Performer because its pricing was always better in the past. I do feel that I got a fair deal this time. Our value-added reseller and our sales guy worked hard to give us a fair deal. I feel that we got a fair deal. We did not go for the pay-as-you-go deal. I did an upfront package. I prefer that. I want to know what my costs are."

"There is no monthly or yearly cost but rather, the fees are based on the amount of traffic that you use."

"The pricing is very reasonable and the licensing is straightforward."

"It's a very expensive solution"

"The solution is expensive."

"It is neither costly nor cheap. It is not too high and not too low. I know the price of other tools, and LoadRunner Cloud's price is in the medium range."
