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

"The features that I appreciate are quite basic. It is easy to ramp up the threads and start calling the application. A lot of connectors can already be found within Apache JMeter, but we are not using the entire set because the integration between the customers and platform is based on HTTP. We are just going to produce lots of HTTP sequences."

"It's a free tool."

"It is open source as well as relatively extendable. It allows us to extend and add additional functionality and features. Its deployment is also very easy."

"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."

"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."

"The solution offers a lot of plug-ins and a huge continuously developing community that is regularly offering new features and plug-ins."

"It's very easy to install, and it's very easy to code and develop the script."

"One valuable feature of Apache JMeter is the ability to replicate scenarios where bulk files have to be uploaded via API."

More Apache JMeter pros

"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."

"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."

Cons

"It's not easy to get the data from one place or to do customizations."

"Modeling a test is difficult. If you don't have much knowledge, you won't be able to do it easily. Testing APIs is also difficult."

"Apache JMeter's UI can be made more colorful."

"One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses."

"To improve Apache JMeter, reducing the complexity of load generators and distribution testing would be beneficial."

"We're like the solution to be more user-friendly."

"Running JMeter in GUI mode uses a lot of memory, which means we need to switch to a non-GUI mode when using a heavy load."

"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."

More Apache JMeter cons

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

"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."

"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."

"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."

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

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

"It is free."

"The solution is open source."

"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."

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

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.”
