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.

Has enabled my team to identify bottlenecks effectively and deliver reliable performance analysis across projects

I have mentioned many advantages about this product, but to discuss disadvantages or areas that could be improved, I would need to consult with my engineers who are working on it. So far I have not heard of any significant issues. I can gather specific improvement suggestions from my architect and provide that information later.

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. What it does, it does great, but it only gives you limited types of protocols.

I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

"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."

"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."

"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."

"Compared to some other vendors, there is a lack of community support."

"LoadRunner Professional's parameter data could be improved."

"To be frank, the earlier version (graded I-5 and graded I-6) was very bad for me."

"If they can make LoadRunner more comprehensive, it would really help."

"I think it needs to have better reporting."

"If the support of the protocols was the same throughout the other protocols and it was there evenly, then I would rate the product higher."

"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."

"We'd like the solution to be a bit more user-friendly."

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."

"The pricing model and the software licensing model could be better."

"The licensing of Micro Focus LoadRunner Professional could improve. If it can be easier and the concurrent run can be included with the current total number of users, it would be helpful."

"The licensing fees are based on the number of users."

"The cost depends greatly on the needs of the testing engagement."

"The licensing model is complex. You have to pick up the protocol and the number of concurrent users, and then select the level of concurrent users. For example, there would be one price for 100 to 500 users and another for 500 to 2000 users. If you choose two protocols, then you will have to pay twice the amount depending on the number of concurrent users."

"The solution's pricing is expensive."

"The licensing is on a yearly basis and is relatively expensive."

"OpenText LoadRunner Enterprise's pricing is reasonable."
