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

"I like the fact that JMeter integrates well with other tools."
"It's an open-source tool, Apache JMeter, it's easy to customize and it provides an enormous amount of plugins, so based on the customer requirements we can customize our code and execute the test, and JMeter integrates well with Jenkins while the cloud offers CI/CD activity."
"Apache JMeter is completely free as it is open-source, providing cost-effective customization options."
"Scripting with the solution is good."
"The solution has good transition controllers and distributed testing."
"The most valuable feature of Apache JMeter is its popularity. It is the best open-source tool with all the features needed."
"Apache JMeter is stable."
"I definitely recommend Apache JMeter to other users because it is an open-source tool; compared to LoadRunner, you save a significant amount of money, installation is hassle-free, and there are no additional components compared to other tools."
"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."
"We find the product to be scalable."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"It stores good reports, as in, improved reports if compared with the SoapUI. It also has in-built security. You just need to switch and check the security testing. My team has never used it, but I know ReadyAPI provides those facilities as well."
"The performance and reporting of this solution have been its most valuable features."
"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 has helped improve productivity and functionality."
 

Cons

"The reports in Apache JMeter could improve."
"One area for improvement is the ability to decrease load suddenly during tests. Currently, we need to use multiple separate JMeter instances to simulate reductions in load, which isn't ideal."
"They can provide support for other protocols as well, and with AI becoming more prominent, they can implement features where it can generate code by itself based on the results or provide suggestions."
"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."
"There is some work to be done with the integration."
"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."
"It should start supporting the presentation layer. It currently provides performance testing specifically at the application and API level. It can be extended to the presentation layer, which includes mainly Angular and React frameworks. It should also be easy to use and easy to train people."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"It is very slow sometimes."
"The solution’s interface could be improved."
"This solution could be improved by offering artificial AI testing in addition to API testing. For example, we would like to have machine learning testing because when test applications, manual work could be completed automatically using this functionality."
"We need some time to understand and configure the solution."
"I want the solution to be able to monitor Apache Kafka activity as well."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"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."
"It is very slow sometimes. If they could improve its performance, it would be really great for the users."
 

Pricing and Cost Advice

"Free"
"This is an open-source solution, so there are no licensing costs associated with it."
"Apache JMeter is a free tool."
"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."
"This is an open-source solution, so there are no licensing costs involved."
"I was using the free version of the software."
"We are using the free version, and if required, we can easily switch to the other version."
"There are operational costs related to using Amazon Cloud, but the tool itself."
"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."
"We find the cost to be affordable."
"ReadyAPI Performance’s pricing is reasonable."
