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.

Good reporting and interface, but supports limited types of protocols and requires low-level script editing

It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

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."

"The most valuable feature in JMeter is the Thread Group, which helps us to see whether the performance is good."

"What I like best about Apache JMeter is its user-friendly GUI because even if you don't have very good coding knowledge or understanding, or even if you don't come from a development background, you can still use the solution with just a few clicks. This is what's unique about Apache JMeter, in comparison with other tools in the market. As Apache JMeter is open source, when there's a missing feature, you can search in several community blogs for plugins that you can use to modify Apache JMeter to meet your requirements, and this is another advantage."

"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."

"The most valuable features are the integration with Jenkins and the reporting."

"The distributed load testing is very good and the ramp-up, and when we come out with the right ramp-up plan, it can be converted into Apache JMeter script very well, accurately simulating how many of our transactions need to be triggered."

"The most valuable feature of Apache JMeter is its popularity. It is the best open-source tool with all the features needed."

"We find the ease of use and the reports and graphs available valuable."

More Apache JMeter pros

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"Using service virtualization, we are able to accelerate the testing and development activity."

"All IBM testing tools are really well integrated."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

Cons

"I am not satisfied with this solution. Its UI side is not so easy to use for beginners."

"The reporting section of the solution can be better."

"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 sometimes found the documentation to be not as explanatory as I would've liked it. In the cases that I can think of, I was looking for a rather hand-holding approach with Step A, B, and C, but then I realized that with a product that is open source like this, you can't do handholding. That is because there are so many different uses and different unique environments and setups for it, but I remember thinking a few times that if they only just said this."

"The GUI of Apache JMeter is not that user-friendly because we have many proxies, and we have to record through the proxy."

"We would like some reporting and analysis tools to be added to this solution."

"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."

"JMeter is a good solution but it requires writing manual scripts and takes longer than BlazeMeter. It takes longer to cover the same number of use cases and is not as user-friendly."

More Apache JMeter cons

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there."

"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

Pricing and Cost Advice

"The solution is free of cost as it is open source."

"The solution is open source."

"Apache JMeter is a free tool."

"JMeter is open source and available free of charge."

"No licensing is required as it is a free, open-source tool."

"We are using the free version."

"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."

"The solution is open source with no user fees or licenses."

More Apache JMeter pricing and cost advice

"It doesn't really concern me. Licensing is on a yearly basis."

"The pricing is a little bit on the higher side, although it is really good."
