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 distributed load testing is very good with Apache JMeter."

"We had some challenges testing HTTP/2 APIs, which are becoming more prevalent with advancements like 5G. So, we added another plugin to help with HTTP/2 API load testing. Apache JMeter, with additional plugins, now supports HTTP/2, which is critical as everyone moves from HTTP/1 to HTTP/2."

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

"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."

"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."

"JMeter's open-source nature allows us to create scripts easily, add any number of users during load tests, and handle large volumes of data without additional cost."

"The ease of use is the solution's most valuable feature. Also, the ability to easily create test cases is also very good. It's easy to just ramp up on the solution."

"It's stable and reliable."

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."

"Customization and extensions made in Java is valuable because this can help you set elements to improve your results."

"Once you are used to this tool, it is user friendly and provides very good analysis for web applications."

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

"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."

"It has improved our visibility of reporting and simplifying performance testing for larger projects/programs."

"With each new version, the tool gets better and better features."

"It's definitely helped in scaling the performance of our application."

More IBM Rational Performance Tester pros

Cons

"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."

"I have not seen a return on investment right now, as there is no improvement in Apache JMeter and reduction in cost, but I save time and reduce costs with Apache JMeter."

"I think it has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems when we are working in certain specific environments that have a proxy setup."

"Its reporting could be improved. There should be a better visual representation. That would be helpful for easy consumption of the reports."

"If you want stability, you will have trouble, because the system is not uniform."

"Improving JMeter's sync time would be beneficial."

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

"JMeter output reports are only good for the people who understand the detailed logs."

More Apache JMeter cons

"Support for more protocols is required."

"It is complex for a novice."

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

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

"It was complex."

"I’d like to see a tighter integration with Rational Quality Manager and the Jazz platform."

"The tool has lots of limitations."

"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."

More IBM Rational Performance Tester cons

Pricing and Cost Advice

"Apache JMeter is a free tool."

"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."

"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."

"Since we are using an outsourced solution, it is not paid for by our company."

"Everything is included, and there are no additional costs."

"Since it is an open-source product, buying or paying for any license is unnecessary. One just needs to download it to be able to use it."

"The product has reasonable pricing."

"The solution is open-source."

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."
