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 helps by detecting bottlenecks."
"It's easy to use and free, a huge community, and it offers a risk free to start, so use it for application performance testing."
"Apache JMeter is quite flexible and it is also well distributed."
"A lot of things are valuable. It is free. It has a lot of features, such as report generation and integration with CI/CD, which makes it very competitive with the other paid solutions available in the market. It is a good solution."
"From the customers' perspective, the most valuable feature is the price."
"The solution is comparable to LoadRunner because it works with multiple plugins but is free to use."
"I recommend JMeter if your goal is to design some stress tests."
"It is easy to set up."
"Eventually, we enhanced the whole automation, and how it should get integrated with the hardware, or another tool like Jenkins for CI/CD automation."
"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."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
"We find the product to be scalable."
"It has helped improve productivity and functionality."
"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."
"The performance and reporting of this solution have been its most valuable features."
 

Cons

"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."
"They should improve the solution on its UI front."
"What needs improvement in Apache JMeter is the very high load requirements when you want to scale it beyond certain thresholds. For example, small to mid-range testing is very easily done with Apache JMeter, but if you scale and increase the load, then it would be a problem because the tool consumes a lot of resources, probably because Apache JMeter provides an enriched UI experience, so it consumes a lot of memory and requires high CPU usage. This means you have to manage your infrastructure, or else you'll have high overhead expenses. As Apache JMeter is a heavyweight tool, that is an area for improvement, though I'm unsure if Apache can do something about it because it could be a result of the way it's architected. What I'd like to see from Apache JMeter in the future is for it to transition to the cloud, as a lot of cloud technologies emerge around the globe, and a lot of people prefer cloud-based solutions or cloud-native tools. Even if a company has a legacy system, it's still possible to transition to the cloud. I've worked with a company that was an on-premise company that moved to the cloud and became cloud-native. If Apache JMeter could transition to the cloud, similar to k6, then it could help lessen the intense resource consumption that's currently happening in Apache JMeter."
"Given that Apache JMeter is a free and open-source tool, documentation improvement may not be a major concern, as it is mostly contributed on a voluntary basis. The essential information is already available. However, in terms of the interface, there are occasional bugs, and the tool may not address them as quickly as some users would like. Fixing defects and bugs might take a considerable amount of time, with users sometimes having to wait for several months or even a year for the next release to address specific issues."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"From an improvement perspective, consider a scenario where your application needs to retrieve data from PayPal and store it in an Excel file in an external network."
"The reporting is not very good."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"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."
"The solution’s interface could be improved."
"We need some time to understand and configure the solution."
"I'd not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes."
"I want the solution to be able to monitor Apache Kafka activity as well."
"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."
 

Pricing and Cost Advice

"This is an open-source solution, and there are no fees."
"There are operational costs related to using Amazon Cloud, but the tool itself."
"Apache JMeter is a free open source solution and it is why we are using it."
"The product has reasonable pricing."
"We didn't pay licensing fees for Apache JMeter because it's an open-source tool. We only paid for the machines where we installed Apache JMeter modules."
"This is an open-source solution, so there are no licensing costs involved."
"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."
"This is an open-source product."
"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."
