Leveraging cost-effective customization with powerful plugins but complexity reduction needed
Apache JMeter offers plugins for reporting and preparing test scenarios. It allows recording to customization, letting you download plugins to connect with databases or external systems. Despite being open source, it offers features comparable to paid tools, and its ability to customize and expand is particularly useful. Additionally, its open-source nature makes it cost-effective.

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.

Quotes from Members

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

Pros

"The metrics part of it and the ability to write your custom code to do some specific tests in the performance testing space are the most valuable features."
"It is scalable. It is cloud-based."
"It's very easy to install, and it's very easy to code and develop the script."
"The biggest thing I liked about it is that there is a huge user base out there, and being shareware and being Apache, if I have any question on how to get something done, I get 18 different answers. Out of those, there would be at least a few good approaches for what I was trying to do. So, the support system out there is most valuable."
"Apache JMeter is completely free as it is open-source, providing cost-effective customization options."
"We are using it just for load testing. We are using its free version, and it is scalable."
"The reports and analysis tools are very good. They are the solution's most valuable features."
"When there's a high number of TPS I can achieve more transactions per seconds given the hyper-limitations."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
 

Cons

"Documentation is not comprehensive, making it difficult to find the right answers."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"In this tool, automation in general is almost non-existent. Everything is done manually."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"If JMeter could provide a web version of editing, that would be good."
"JMeter is lagging when it comes to GUI performance testing because we need to install some third-party plugins for recording the GUI script, and the performance isn't very reliable."
"There is some work to be done with the integration."
"The interface could be made more 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. 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."
"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."
 

Pricing and Cost Advice

"This is an open-source solution, so there are no licensing costs involved."
"The solution is open-source."
"Everything is included, and there are no additional costs."
"In terms of open-source adoption, it is completely free."
"We use the open source version."
"The tool is open-source."
"It is open source. There are no licensing costs associated. If you need enterprise support, you'll probably end up paying for a license. You would also factor in the infrastructure cost, but that's not significant."
"Apache JMeter is a free tool."
"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."
