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

"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."

"Using service virtualization, we are able to accelerate the testing and development activity."

"All IBM testing tools are really well integrated."

"We can determine response times for our external applications, from most places around the world, for a small fee."

"The solution is easy to use."

"The record and playback feature is the most valuable feature. It's all driven by the script, so it's a script-based tool where the background tracing starts. Java's background process does a lot of tracing. The process starts in the background. It sees what peaks of volumes that the process can handle. It's easy to use because it's script based, record, and playback. I"

"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."

"It's been extremely scalable as far as the testing that we've done with our customers."

"It is feature-rich. It supports most protocols, which is important because I am in charge of a team at the bank, and we do performance testing for all kinds of different applications. We have tons of them. We even do video streams."

"It's a fast product, so you don't have much trouble in terms of maintenance overhead. You don't want to just look into configuring load generators, look for upgrades, and end up having that take up a lot of your time. With this solution, you just log in and you start using it. This means that there is a huge benefit in terms of the overhead of maintaining the infrastructure and the maintenance effort."

"The most valuable feature is having load generators in countries where we don’t have access to them."

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.

"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."

"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."

"Because it is a paid tool, its cost is very high."

"CI/CD integration could be a little bit better. When there's a test and if you see that there are high response times in the test itself, it would be great to be able to send an alert. It would give a heads-up to the architect community or ops community."

"The cloud configuration setup and server access can be tricky, as we don't usually get direct access."

"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."

"We ran into some undocumented limits around the number of concurrent users."

"We initially had some problems with the setup as we had an issue while configuring load generators with the tool."

"Some improvements can be made to the solution's user interface"

"One area for improvement in LoadRunner Cloud, especially for agile models, is its limited support for functional testing alongside its robust non-functional testing capabilities."

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."

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

"The solution is expensive."

"Pricing is dependent on what you're referring to. If you're talking about the cloud, it's likely competitive. However, if you're talking about the on-premise version, professional or enterprise licenses are required. Prices are on the high side. They are not cheap."

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

"The solution’s price is considerably high."

"The pricing for OpenText LoadRunner Cloud is average."

"It's a very expensive solution"

"We make use of virtual user hours. We buy time in the LoadRunner Cloud. It costs around $80,000."
