Have built custom performance test scripts and integrated them into automated pipelines seamlessly

Apache JMeter has its own pros and cons when compared to other tools. It is easy to use the tool and it has open-source capability so we can build our custom scripts and execute them. It provides other capabilities, such as integrating a database and connecting to other application servers for monitoring and related functions. We use dynamic HTML reporting, which helps us in testing analysis by pinpointing the bottlenecks based on the reports. We can identify the specific areas that need attention, troubleshoot them, and report to the development team. The user-friendly GUI for creating and managing tests makes it very easy to drag and drop samplers. For example, if you want the HTTP sampler, you can drag and drop it and use it. For configurations, we have other samplers. For results, we have the view results samplers that we can also drag and drop. The UI is good in comparison with other tools. Regarding integration with CI/CD pipelines, we can create Apache JMeter scripts and use the Docker image. From the image, whatever scripting we have done can be connected. We can use the CI/CD pipelines and connect them with Jenkins tools and GitHub. Then we can create the pipelines and automate the end-to-end flow. For connecting Jenkins to Apache JMeter, JMeter plugins are available, and we have used them. Apache JMeter also has some third-party plugins, which are not native samplers. If we want to use custom test executions, we definitely use all the different plugins available in Apache JMeter. The capability to simulate users has impacted testing resources and outcomes as Apache JMeter is based on Java, which has a limit to the users in a particular load generator. Apache JMeter provides distributed load testing where you can connect multiple PCs in a master and slave concept, allowing you to pump the load with any number of users. In the past, I have done load testing with 10,000 users by connecting the Apache JMeter distributed network in BlazeMeter. There is a cloud version available, the updated BlazeMeter, and I used that. It is very easy to launch load generators in BlazeMeter, and then we can run the test, scaling up beyond 10,000 users.

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

"If you want to test your application out and not incur a lot of costs, it is probably the best tool."

"They can easily view the results and gain valuable insights."

"Very easy to download and setup the entire infrastructure (Controller + LGs)."

"The benefit of JMeter is that it does our performance testing and provides a report without the need to spend money on a licensed tool, which is a significant benefit for us and for the project we're currently working on."

"It's a powerful tool that is open source."

"I appreciate JMeter's simplicity and power for performance testing."

"The most valuable feature in JMeter is the Thread Group, which helps us to see whether the performance is good."

"The solution is scalable."

More Apache JMeter pros

"All IBM testing tools are really well integrated."

"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."

"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."

Cons

"Apache JMeter could use improvement in reporting. Currently, it isn't easy to generate reports in PDF format. While receiving reports in PDF format is possible, it requires a lot of customization. Additionally, when comparing the load test to others solutions it could improve."

"Recording the script is also not flexible in JMeter."

"JMeter's reporting is extremely rudimentary. The fundamental reporting mechanisms need to be drastically improved. It doesn't utilize an automatic session management mechanism or methods other tools use like parsing cookies and variables. Everything needs to be done manually. There's no automation."

"I sometimes found the documentation to be not as explanatory as I would've liked it."

"You really need a technical team in order to really utilize the product."

"For UI automation, it is limited and therefore rates a one."

"Apache JMeter could be a more user-friendly product from the end user's perspective."

"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."

More Apache JMeter cons

"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."

"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."
