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.

Scripting and basic test executions are good features; configuring the workload for tests is easy

In terms of areas of improvement, I would say the Silk Performance Explorer tool, which is used for monitoring and analysis, can be improved because that's where we spend most of our time when we're analyzing the test data. Any enhancements that can be provided in the monitoring sphere would be useful. When you have a large amount of data the tool struggles with it and will sometimes crash, or there may be issues with too many metrics being collected when running a test. The interface for the scripting could be more feature-rich. Integration with tools like Prometheus or Grafana where we can visualize the data would be great. As things stand, we have to use one monitoring tool to visualize data and another for visualizing the test metrics. Integration would enable us to see the metrics from Silk and correlate that with the metrics from other servers or other processes we're monitoring. It would save having to look at Silk data and server metrics separately. It's the way things are going with newer tools. I think the solution is being phased out by Micro Focus and their emphasis is focused more on LoadRunner. We haven't seen much development in the last few years.

Quotes from Members

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

Pros

"The reports and analysis tools are very good. They are the solution's most valuable features."

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

"I appreciate JMeter's simplicity and power for performance testing."

"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."

"Apache JMeter helps my testing analysis by providing precise reports; the HTML format report gives me the exact transactions, response times, and graphs that show average response times, as well as throughput per second."

"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 is scalable. It is cloud-based."

"The solution is scalable."

More Apache JMeter pros

"A good monitoring tool, simple to script and easy to configure."

Cons

"Automation is difficult in JMeter."

"In future releases, it would be helpful if there was an integration with ALM Octane."

"To the best of my knowledge, the documentation could be improved. It should be enhanced to better support newcomers. Currently, only people with some experience can easily understand the content. Including more sample programs, applications, and use cases would help many more people adapt to using the solution."

"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."

"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."

"The UI could be better."

"While using Apache JMeter, we are unable to view the graph while the test is running because it consumes resources, which is a drawback. With BlazeMeter, you can view the results in real-time."

"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."

More Apache JMeter cons

"If you have a large amount of data, the solution can struggle."

Pricing and Cost Advice

"Apache JMeter is a free, open-source solution."

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

"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."

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

"We use the open source version."

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

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

"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"

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.”
