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.

Reliable with excellent support but needs better source control integration and versioning

Source control integration and versioning could be better. Currently, StresStimulus does not natively support any form of change control management. Result analysis (snap-out tabs for side-by-side comparisons) need improvement. Multiple sets of analysis results can be opened in the user interface at the same time, and comparison reports can be generated to compare some aspects of pairs of test runs. However, the interface that displays the multiple sets of results only allows a single result set to be viewed at any one time & uses tabs to switch between the individual result sets. It would be useful to have the ability to view multiple tabs at once, either side by side in the interface or by snapping tabs out of the interface into their own windows to be viewed together with others. Graphing (collect PerfMon data as part of the tests and then have the ability to create different graphs with that data after the test completes to help with analysis) could be better. Graphs and their contents have to be defined before tests are run. Often, as a result of running tests and viewing the results collected, it is necessary to have graphs showing/comparing different metrics collections than those specified before the run. Other tools collect metrics that are not tied to pre-defined graphs & allow the metrics to be used to construct graphs as required by subsequent analysis & investigation. Nested tests/test case groups/test solution files (ability to build a hierarchy of test cases/test case groups/solution files) are required. Within a StresStimulus, tests are organized in just two levels, test cases, and test case groups. As is possible with other tools, it would be helpful to have a hierarchy with multiple levels of nested test cases/test case groups (or even the solution config files themselves). It would make it easier to manage multiple sets, combinations of tests, load profiles & test mixes if a high-level solution file (or test case group) could run a collection of lower-level ones, which in turn end up executing multiple different base-level test case groups and individual test cases.

Quotes from Members

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

Pros

"Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version."

"We find the load testing feature valuable."

"The solution is free. You don't need to worry about licensing costs."

"The metrics part of it and the ability to write your custom code to do some specific tests in the performance testing space are the most valuable features."

"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."

"It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."

"It's open source, so I like that about the product. And there's a lot of community support for it."

"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."

More Apache JMeter pros

"Compared to other tools, there is not a whole lot to Stress Stimulus UI. This makes it easy to use, be it while scripting, executing, or having to train someone new to the team."

"Designed to be a modern testing tool, StresStimulus made it easy for us to upgrade from an older deprecated testing tool and adapt to Agile DevOps testing principles by shifting left with performance testing."

"Technical support is great."

Cons

"The only thing is the learning curve. It's high."

"You really need a technical team in order to really utilize the product."

"The UI needs some work. The first time I used JMeter, I couldn't record the full scenario to mimic the user experience. Since then, they have introduced some plugins and a third-party tool called BlazeMeter."

"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution. In terms of reporting, runtime monitoring is not currently included, and it should be included. They can also improve it on the reporting side in terms of the comparison of the reports. They can also focus more on integration with CI/CD. Currently, people are using their own customized tools. It would be nice if Apache can provide some standard tools and procedures for integration with CI/CD tools like DPR. There are some tools, but it would be nice if official standard tools and procedures are available."

"The installation needs some work. It could be simplified."

"At times when we overload the application, it gets stuck...After the solution gets stuck due to overloading, we have to restart our computers. In short, the solution keeps crashing."

"The solution needs more metrics for reporting."

"I need to consider it further because as features increase, it might become more complicated, and my goal has always been simplicity. Currently, I have to focus on other tasks, and I'm handling multiple responsibilities, so I can't juggle everything at once. However, if you ask me, I believe EJB covers most functionalities that are crucial. One improvement I'd suggest is adding a graphical aspect to the Gateway, making it a bit more colorful. Unlike JMeter, which lacks color, having a bit of color in the graphical aspects would be beneficial. Overall, for the essential features, EJB should work fine."

More Apache JMeter cons

"We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection."

"StresStimulus has a dedicated blog where users of the tool can log new feature requests or enhancements to existing features."

"Result analysis (snap-out tabs for side-by-side comparisons) need improvement."

Pricing and Cost Advice

"We are using the free version, and if required, we can easily switch to the other version."

"This is an open-source solution, and there are no fees."

"Apache JMeter is a free tool."

"Since we are using an outsourced solution, it is not paid for by our company."

"This is an open-source solution, so there are no licensing costs associated with it."

"The solution is open-source."

"There are operational costs related to using Amazon Cloud, but the tool itself."

Overview

Apache JMeter is an open-source Java application that tests load and functional behavior and performance in applications. Created initially to test web applications, it has expanded its functionality to test other functions. For instance, you can test a server to see how efficiently it works and how many user requests can be handled simultaneously.

You can use JMeter to test functional performance and regression tests on different technologies. This Java desktop application has an easy-to-use graphical interface which uses the Swing graphical API. You can run JMeter on any environment that accepts a Java virtual machine, such as Windows, Linux, and Mac.

What protocols does JMeter support?

Web - HTTP, HTTPS
Web services - SOAP/XML-RPC
Email service - POP3, IMAP, SMTP
FTP service
Database via JDBC drivers
LDAP
Native commands or shell scripts
TCP
Java objects

How does JMeter work?

JMeter sends requests to a target server by simulating a group of user requests. Then it collects and calculates statistics on the performance of the target. This target can be a server or an application.

You can test the performance of static resources, such as JavaScript or HTML, and dynamic resources, such as JSP, Servlets, and AJAX. It is also helpful to determine how many concurrent users your website can handle.

There are two main tests you can carry out with JMeter: load test and stress test. The load test models expected usage of a server by simulating multiple users accessing the web server simultaneously. The stress testing aims to find the maximum load capacity of the server or application.

Apache JMeter Key Features

JMeter enables fast test plan recording, building, and debugging via a featured test IDE (integrated development environment).
Command-line mode allows carrying out load tests from any OS compatible with Java.
JMeter can extract data from most popular response formats, such as HTML, JSON, XML.
JMeter is entirely portable.
A multithreading framework allows you to simultaneously test multiple samplings and separate thread groups.
Thanks to the caching feature, you can conduct offline analysis or replay test results.

Apache JMeter Benefits

As open-source software, it is freely available and continuously improved.
The setup is user-friendly, and no installation is needed.
The GUI (graphic user interface) is intuitive and easy to use.
You can write your own tests and use the visualization plugins to extend the testing.
It is a platform-agnostic tool. For example, JMeter can work with Linux by clicking on the JMeter shell script. On Windows, you can call up JMeter by starting the jmeter.bat file.
Since the test plans are stored in XML format, you can generate a test plan using any text editor.
You can simulate a heavy load on a server, a group of servers, a network, or an object. Use JMeter to test an application or server's strength and performance under different load types.

The JMeter extensible core has numerous benefits:

Unlimited testing capabilities via pluggable samplers.
You can choose multiple load statistics with pluggable timers.
Visualization plugins and data analysis enable customization.
Continuous integration via third-party open-source libraries (Maven, Gradle, and Jenkins).

Reviews from Real Users

Stephen B., I.T. Architect, Analyst, and Developer at an educational organization, says, "The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."

"I like the fact that JMeter integrates well with other tools," adds the Founder and Principal Consultant at a tech services company.

A Quality Engineering Delivery Leader at a financial services firm says, “The performance of the solution is excellent. They have designed the product so that it is very easy to configure. You can basically do anything you like with the product. It's not very restrictive. We like the fact that the technology is open-source.”
