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

"When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"This solution is easier to use than any other tool in the market; there is not even a requirement to learn a lot of scripting in order to use it."
"The most valuable feature of this solution is that it is free."
"It is scalable. It is cloud-based."
"API testing, Database Testing, and MQ testing can be done with ease."
"I like the ease of using JMeter, as it can be downloaded and used to record and run load tests, and it can record, run and create reports easily without the need to have licenses, complex installations and paid support."
"The distributed load testing is very good with Apache JMeter."
"They can easily view the results and gain valuable insights."
"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."
"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."
"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."
"he initial deployment process is easy."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"The performance and reporting of this solution have been its most valuable features."
"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."
 

Cons

"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."
"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."
"RegEx Extractor needs improvement. It's a headache for many people."
"Reporting feature can be improved to provide better test results."
"To improve Apache JMeter, reducing the complexity of load generators and distribution testing would be beneficial."
"We are going to migrate away from JMeter in the near future."
"The only thing is the learning curve. It's high."
"The reporting section of the solution can be better."
"We need some time to understand and configure the solution."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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 client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"It is very slow sometimes."
"I want the solution to be able to monitor Apache Kafka activity as well."
"The solution’s interface could be improved."
 

Pricing and Cost Advice

"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."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"Apache JMeter is a free, open-source solution."
"In terms of open-source adoption, it is completely free."
"I haven't looked into it. Most of our projects are nonprofit or grant-based. Everything is public commons, so we don't really have to worry about that so much."
"It is free."
"Since we are using an outsourced solution, it is not paid for by our company."
"ReadyAPI Performance’s pricing is reasonable."
"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."
