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.

Performance testing has supported web app peak analysis but needs better setup and smarter scripting
Regarding points for improvement for OpenText Enterprise Performance Engineering (LoadRunner Enterprise), I see that features are not being fully developed yet. If OpenText could think about bringing AI features into the tool, it could save maximum time in scripting or make scripting effortless, particularly in correlation, which is where the complexity involved in script development exists. If any AI features could replace or eliminate more manual work on the correlation part, that is where we could see a game-changing improvement for the tool. OpenText Enterprise Performance Engineering (LoadRunner Enterprise) can be positioned very well in the market. However, I see that the basic correlations are only being handled by the autocorrelation engine in the LoadRunner tool, and I would expect a few improvements to handle even complex correlation problems so that the tool can be appropriately positioned compared to their peers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"All IBM testing tools are really well integrated."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"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."
"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."
"It's the most flexible and best solution for our people who are both offshore and onshore because of the reporting capabilities."
"Performance Center, in our company, is used for important applications where we have a lot of users, or special needs for performance that are important."
"The tool is very easy to set up and get running."
"We have high confidence that the results are reliable, it's helped catch multiple bugs before they've gone to production, and we're able to more confidently release software into production."
"LoadRunner Enterprise's best feature is the detailed reporting structure."
"It is mostly user-friendly and usable."
"IP Spoofing can be done using Performance Center."
"If it is in the airline industry, I would definitely suggest to them, "Okay, this is a perfect product because of the number of protocols it supports," because we looked at other open source software and we couldn't find a product which matches Performance Center, which supports so many protocols."
 

Cons

"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."

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."
"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."
"On the newer versions, I think the bleeding edge is still being worked on."
"The technical support offered by the product is an area of concern where improvements are required."
"We'd like the product to include protocol identifiers whenever a tester wants to test a new application."
"OpenText LoadRunner Enterprise needs to improve reporting."
"Currently, when we try open LRE we encounter cookie banner issues. However, I'm not sure if it is within the enterprise solution or with the vendors."
"While the stability is generally good, there are a few strange issues that crop up unexpectedly which affect consistent use of the product."
"OpenText needs to improve in terms of support. With the same support plan but when the product was owned by HP, support was more responsive and better coordinated."
"The cost of the solution is high and can be improved."
 

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 prices would differ depending on the number of licenses you need. I wouldn't maybe compare it to any other tools. I rate the price as seven out of ten."
"I give the cost a one out of ten."
"I rate the product's pricing a three out of ten."
"We got a very good deal. We are happy with that. We have 5,000 licenses."
"There is an ROI. What LoadRunner does, is it prevents failures when there are many, many concurrent users in the systems of a company."
"The price is a bit too high."
"We are content with the pricing and find it to be reasonable in terms of value for money."
"ROI is 200%."
