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.

Supports web and mobile applications, very scalable, very stable, and wonderful support

There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies.

Quotes from Members

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

Pros

"The most valuable features of Apache JMeter include SCTP sampler, throughput controllers, stepping up thread group, parallel controller, timers, and the ability to use gRPC protocol."

"JMeter is user-friendly, and that's a notable advantage of JVTech. It's straightforward and easy to use, unlike some other load testing tools, making it very easy to understand."

"JMeter is very easy for a user who doesn't have too much programming knowledge, as scripting is not mandatory nor essential to create the testing scenarios."

"The thread groups, samplers, and listeners, which are all determined by the script's requirements, are the most valuable features of this solution."

"It gives accurate results and recommendations that we can implement to enhance the performance of websites."

"The most valuable features of Apache JMeter are user-friendliness, large resource, and the quality of assistance they provide. Additionally, it is easy to integrate with cloud platforms, such as AWS."

"It's very easy to install, and it's very easy to code and develop the script."

"The most valuable feature of this solution is being able to launch many requests and scheduling simulating human interactions with the application."

More Apache JMeter pros

"This tool is very scalable, and for large scale tests, i.e., 5000 virtual users and up, it performs very well."

"Comprehensive Rational Performance Tester results allow testers to identify bottlenecks in the systems under test."

"I strongly recommend this solution to others."

"The setup was straightforward, it depends on the company's regulations and infrastructure policies."

"Real time view and its inbuilt root cause analysis tools is something which I like the most."

"Less coding is needed, it is easy to understand, and it is easy to integrate with existing systems so I can test more than one performance test type, including load testing, stress testing, and scalability testing."

"Virtual Users."

"Rational Performance Tester was perfectly suited to provide the means to monitor the availability and performance of our web services."

Cons

"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."

"Because so much is being done these days with authentication processes, a better system for either getting bearer tokens or some kind of token-based authentication prior to executing APIs would benefit the product. It is there, and you can do things. It is just not real clean at this point. There should be a better authentication process for JMeter or some automation or better guidelines for gaining and utilizing tokens on the fly."

"Self-healing and page rendering for the end-users are not available in Apache JMeter."

"I think JMeter hangs up on large loads."

"The solution needs more metrics for reporting."

"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution. In terms of reporting, runtime monitoring is not currently included, and it should be included. They can also improve it on the reporting side in terms of the comparison of the reports. They can also focus more on integration with CI/CD. Currently, people are using their own customized tools. It would be nice if Apache can provide some standard tools and procedures for integration with CI/CD tools like DPR. There are some tools, but it would be nice if official standard tools and procedures are available."

"What needs improvement in Apache JMeter is the very high load requirements when you want to scale it beyond certain thresholds."

"In future releases, it would be helpful if there was an integration with ALM Octane."

More Apache JMeter cons

"The HP tool is overall a little better but much more expensive."

"The installation and tool setup can take some time, since this involves several components."

"The tool has lots of limitations."

"Installation and configuration processes, and support from IBM all need to be improved."

"It is complex for a novice."

"We had open many PMRs for problems found in the products, and I'm not sure if all of them have been fixed."

"Sometimes new versions have bugs."

"Reporting needs improvement to provide more customization options in the performance test analyst to build custom reports."

More IBM Rational Performance Tester cons

Pricing and Cost Advice

"The solution is free of cost as it is open source."

"The product has reasonable pricing."

"JMeter is open source and available free of charge."

"This is an open-source solution, so there are no licensing costs involved."

"It is free."

"I switched to Apache because it is free. Other tools are much too expensive and can cost up to $50,000 a year if you are looking at commercial options."

"There are operational costs related to using Amazon Cloud, but the tool itself."

"Free"

More Apache JMeter pricing and cost advice

"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."
