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.

Experience a decade of seamless performance with robust support

I would like to improve OpenText LoadRunner Professional based on what we discussed in our last discussion, as those points remain similar and applicable. For future updates, I would like to see the same features that people generally prefer. I find that AI functionality in OpenText LoadRunner Professional should be improved and more accessible; if we get a chance to work with that, then we can check how much it helps.

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.

"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."

"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."

"Lacks specific level monitoring."

"The debugging capability is difficult to use and should be improved."

"The technical support is not as great as we expected them to be."

"Customer Service: I'd say that customer service is not good. Technical Support: Technical support is also not good."

"It needs to be easier to use. I know LoadRunner so I think it's a tool that's difficult to understand."

"The only scenario we see a complexity is when we have single-page applications where JavaScript is talking to the server and coming back. That's the only scenario where we find some difficulties."

"I also use the TrueClient feature for browser-based testing. I found the TrueClient feature to be a bit difficult to use and not very user-friendly for automating scripts."

"Scripting should be simpler, it becomes very complex many times."
