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.

User-friendly features facilitate monitoring while support could be more responsive

I am satisfied with OpenText LoadRunner Cloud as a product, but the ticket resolution time is concerning. The technical personnel are not able to fix issues quickly, which becomes problematic during critical situations. Compared to previous support, I notice that while experts previously resolved issues immediately, current experts take more time to resolve issues, which is the main challenge we are facing. They are now lacking regional support, which takes more time than it used to. My suggestions for improvements to OpenText LoadRunner Cloud would be to have specific experts available who can resolve issues more quickly, as delays can impact project timelines significantly.

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."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

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

"The most valuable feature is the ability to configure browser settings for different operating systems and on different versions without the need to install every single version on each machine and to manage them."

"The most valuable feature is that we do not have to accommodate the load-testing infrastructure in our own data center."

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

"OpenText LoadRunner Cloud eliminates the need for our own testing infrastructure when running tests."

"The most useful features of OpenText LoadRunner Cloud include getting load through the Performance Center, which is part of the cloud version, where we can monitor CPU and memory utilization, and response times."

"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"

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. 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'd like to see more ability to dive more deeply into the configuration."

"The product must provide agents to monitor servers."

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

"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."

"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."

"There are three modules in the system that are different products packaged into one, and they can sometimes be difficult to figure out, so they should be better integrated with each other."

"An area for improvement is analytics on why response times are slow from certain countries."

"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."

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."

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

"It's a very expensive solution"

"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."

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

"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 for OpenText LoadRunner Cloud is average."

"The solution’s price is considerably high."

"It is expensive compared to other tools."
