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

"Apache JMeter is quite flexible."
"We use Apache JMeter for load testing, where we provide the throughput time."
"User-friendly and open source."
"The most valuable features are the integration with Jenkins and the reporting."
"Due to process automation, I don't have to prepare reports, making it the perfect solution."
"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"The reporting features are really good. There's a lot less latency than other solutions."
"The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."
"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."
 

Cons

"To the best of my knowledge, the documentation could be improved. It should be enhanced to better support newcomers. Currently, only people with some experience can easily understand the content. Including more sample programs, applications, and use cases would help many more people adapt to using the solution."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"There could be improvements in terms of memory utilization. We are going to migrate away from JMeter in the near future."
"The memory utilization in JMeter is very poor."
"At times when we overload the application, it gets stuck...After the solution gets stuck due to overloading, we have to restart our computers. In short, the solution keeps crashing."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"It will be much easier, and beneficial for the individual to run it on their own machines rather than having a high-end infrastructure, more CPUs, or more memory that has been consumed by Apache JMeter."
"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

"The solution is free of cost as it is open source."
"The tool is open-source."
"I was using the free version of the software."
"Apache JMeter is a free open source solution and it is why we are using it."
"We use the open source version."
"It is free."
"Apache JMeter is far less expensive than HP Performance Center."
"Apache JMeter is a free, open-source solution."
"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."
