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.

Open-source and flexible but needs client-side scripting
It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS. Also, the APIs tested with SoapUI can be directly used, avoiding the need to create collections like in Postman. The client-side scripting, if incorporated, would provide a complete solution for performance tests. It can handle user distribution and transaction throughput distribution effectively.

Quotes from Members

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

Pros

"The solution is comparable to LoadRunner because it works with multiple plugins but is free to use."
"The most valuable feature for us is the available information on the forums and to be able to discuss and get answers from the people that are involved in using this tool."
"Apache JMeter is completely free as it is open-source, providing cost-effective customization options."
"It's very easy to install, and it's very easy to code and develop the script."
"It is easy to set up."
"API testing, Database Testing, and MQ testing can be done with ease."
"We really appreciate that the solution comes with a live community, which continuously provided plugins and support protocols."
"Apache JMeter is well-known and widely used among developers, particularly on popular developer forums. While it may not have the most user-friendly interface, it offers strong support through official manuals and various articles from companies providing load testing services. The tool is free, has a substantial community, and serves as a fundamental choice for testers, especially those new to performance testing. While other tools like K6 may be more developer-oriented, JMeter's affordability and accessibility make it suitable for those without extensive performance testing experience."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
"Eventually, we enhanced the whole automation, and how it should get integrated with the hardware, or another tool like Jenkins for CI/CD automation."
"We can scale."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"ReadyAPI automation can help us validate the functionality of most web services, allowing us to find out the exact number of defects before deployment to the user interface."
"It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS."
"The performance and reporting of this solution have been its most valuable features."
"We find the product to be scalable."
 

Cons

"The plug-ins make the reports heavy and they have to be run in non-GUI mode."
"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."
"Considering the kinds of tests we are performing here, where we launch several tests at the same time as a batch request, JMeter is not the best tool for the job. Those kinds of things could be done easily with other tools, like T6."
"The reporting section of the solution can be better."
"In Micro Focus LoadRunner we can go from the UI and we can configure it. There is no such feature in Apache JMeter. There should be UI-based recording history or logs."
"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution."
"Some features still require a certain knowledge level to use effectively, and making these features more user-friendly would be beneficial."
"One of the drawbacks of JMeter is that it can't handle a large amount of load, which forces us to switch to other tools when we need to load more than a 5,000 or 10,000 user load."
"I want the solution to be able to monitor Apache Kafka activity as well."
"We need some time to understand and configure the solution."
"It is very slow sometimes. If they could improve its performance, it would be really great for the users."
"This is an area for improvement with the tool. We unnecessarily use JMeter for some website testing, which we would like to avoid by introducing this tool for API and load testing because it provides load testing features."
"The solution’s interface could be improved."
"I'd not sure if they have the same level of documentation for performance and security testing."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"It is very slow sometimes."
 

Pricing and Cost Advice

"JMeter is open source and available free of charge."
"This is an open-source solution, so there are no licensing costs involved."
"Apache JMeter is a free, open-source solution."

"Free"
"Apache JMeter is a free tool."

"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."
"This solution operates on a licence basis and the usage and cost varies according to the use case. It is more expensive if you include access to the learning center. On average it costs approximately 800 Euros."
"ReadyAPI Performance’s pricing is reasonable."
"We find the cost to be affordable."
