What is jmeter

Performance Testing means testing a web application against heavy load, multiple and concurrent user traffic. Nowadays, it is used for a functional test, database server test etc. Have you ever tested a web server to know how efficiently it works?

How many concurrent users can a web server handle? Let say that one day, your boss asks you to do performance testing of www. JMeter can display test results as a graph for easier reading. To do this, simply: Hover mouse over Test Plan , then right-click. Click on Graph Results. To do this, follow these steps: Save the test plan by clicking on File and then Save. Enter the file name. Select View Results in Table in the left pane. Click on Run in the main menu. Click on Start or on the green start arrow under the main menu.

When the test has been run, results are displayed in the table with the following color coding: Black indicates the number of current samples sent. Blue indicates the current average of all samples sent. Red indicates the current standard deviation.

Data analysis and visualization plugins allow great extensibility as well as personalization. Functions can be used to provide dynamic input to a test or provide data manipulation. How do I do it? Once you have tied your accounts together, you can go through the process of configuring and creating your test via Jenkins. With Maven, JMeter provides a plugin that can be accessed through GitHub, allowing users to run tests through your Maven project as opposed to running them as scripts.

Pre-Processors execute some action prior to a Sampler request, such as getting data from web page. On the other hand, a Post-Processor runs after a Sampler element and is typically used to extract, or parse, data from the HTTP response.

The prev variable is one of several variables used in Apache Groovy scripts before the script is executed. The prev variable can be used in JSR Post-Processor actions, such as getting certain information, such as connect time, latency, bytes, URL information, etc. One of those steps involves initiating the JMeter proxy server to script actions from the browser. Within each of the different JMeter Samplers, there are specific configuration options, including setting various timeout parameters, like Connection timeout, Read timeout, Response timeout, Query timeouts, etc.

If the Sampler does not support timeouts, then it should be set long enough so that it does not timeout during a load test. JMeter has an extensive knowledge base of content and community-backed support. An open-source load testing tool like JMeter requires extensive knowledge of JMeter and programming knowledge, as well as an experienced team to set up and execute tests.

JMeter was one of the early pioneers of load testing, but websites, applications, and APIs have become more complex, and new load testing tools, solutions, and technologies are required. While a free, open-source, option may seem appealing at first, it comes with a lot of additional manual configuration and work.

A web-based solution like LoadView allows testers and teams to focus on load testing, with real browsers, and saves them from the burdens of having to manage load injectors and additional hardware. LoadView supports the latest protocols and technologies, supports third-party tools like Postman, and provides a network of cloud load injector servers from around the world.

There are many great open-source load testing tools, and we discussed a few of them in this guide. It is hard to pass up a free tool, open-source solutions may not offer all the features, out of the box, that you require.

A lot of the paid load testing tools support multiple protocols, third-party integrations, offer scripting tools, and multiple pricing plans, and access to support whenever you need. Additionally, like we have seen with JMeter, it is an extremely complex tool that requires a lot of knowledge to use.

There are many steps involved in setting up the test plan and various configurations that you must consider. If you have not used JMeter before, it may take a few tests to get it just right. Paid load testing tools typically walk you through the process, step by step, so by the end of completing your test plan, it is ready to go.

You will not have to waste additional time creating more tests or going back and reconfiguring the test. If you can find a tool that supports the technologies you need to test, great feature-set, and all within your budget, it is worth paying for a load testing tool. Our load testing solution, LoadView, provides users with best-of-breed cloud-based load testing in a cost-effective package. A lot of the performance execution is now pushed to browsers, so it is critical to have a solution that can script, execute, and simulate real user actions within the browser.

Creating load testing scripts are as easy as navigating through your applications like a normal user. Furthermore, the LoadView platform provides users with a worldwide network of cloud-based load generators, not load generated from your local machine like JMeter offers, which provides more realistic conditions, and therefore, better test and reporting results. JMeter Guide Overview Performance testing is an extremely important aspect of the software and application development life cycle.

How to Perform Load Testing with JMeter: Step by Step Instructions for Beginners An open-source performance testing tool like JMeter provides organizations the ability to run performance tests for their web applications, websites, and APIs, but not have to deal with any upfront investments that come with commercial-based, or paid, performance testing tools.

Step 1: Verify System Requirements Just like any other desktop application, you need to make sure your system meets the necessary basic requirements to be able to run JMeter.

Step 2: Download JMeter Binaries or Source Code Once you have verified that your system meets all the necessary system requirements, you can download the latest JMeter binaries or source files, depending on your specific environment or requirements. Step 6: Create Thread Group Within the Thread Group dialog box, you can set and adjust multiple Thread Properties, such as Number of Threads Users , Ramp-up period in seconds , and Loop Count how many test iterations , as well as additional actions, like delays, test start and stop times, and actions to take after a Sampler error.

Everystep Web Recorder ». Step Execute the Load Test After you have configured all your load test details and settings, you can simply select the Run button in the Tool Bar and your test will begin. Step Review the Load Test Results Depending on what type of Listener you chose, you can view the results as the test runs. Visit Knowledge Base. Earlier in this guide, we talked about what performance testing is and the different types of performance tests that exist under the umbrella of performance testing, such as load tests, stress tests, scalability tests, spike tests, etc.

If we look at what JMeter offers, we will see that it is best suited for executing load tests and stress tests. However, because the load is simulated from your own device, it will be difficult to determine actual real-world test results using JMeter just based on protocol-based tests. In the previous section, we discussed the step-by-step instructions on how to set up a protocol-based load test on a website or application with JMeter.

Step 2: Create the Thread Group Like we covered in the earlier section, the Thread Group window is where you can add the number of users Threads , set the ramp-up time, and number of test iterations Loop Count. Step 4: Add Listeners Listeners are what are used to save and view the test results. Step 5: Run the Test and View Results After you have configured and saved your load test details and settings, you can select the Run button in the Tool Bar and your test will begin.

Step 4: Test Listeners and Run Test Once you have configured the Test Plan, the last item on the list is to add your Listeners, which will display the results of your test. JMeter Alternatives — Free and Paid. As a developer or software tester, you know that while functional testing is important, performance testing is a critical step of the software development process.

Your application may work just fine, but what good does it do if your application does not load properly when hit by hundreds or thousands of users? To the user, this is going to cause frustration and subsequently, they will leave whatever it was they were planning to do.

You cannot hope they will come back. If your websites, applications, or APIs are going to be accessed by many users, whether it is externally, from different geographic regions, or internally, from within your own organization, they need to be tested to ensure load times are low, response times are fast, and that content renders correctly.

All these metrics and more are responsible for delivering a seamless user experience. LoadView also uses the same platform as the solutions in Dotcom-Monitor, so you can use the scripts you created during load testing for continuous monitoring. Lastly, LoadView is constantly developing and releasing new features. Some recent updates include load testing for streaming media and support for load testing Postman Collections. WebLoad WebLoad, from RadView, is another commercial-based, or paid, performance testing solution that you may come across when doing research on find the right load testing tool for you and your team.

However, the on-premises version is like JMeter, where you must host and manage it from your own hardware, but WebLoad providers additional functionality, like hosting it within your own cloud provider, if you have one.

The reasons for why a company would choose to self-host could be due to security issues or policies, as well as just having more control over the deployment. The SaaS-based option is like LoadView, where the testing infrastructure is fully managed for you. Like JMeter, their performance testing product, Eggplant Performance, must be installed on your local system. And like any software, there are certain prerequisites that must be met to be able to install it.

Even more, Eggplant Performance is made up of multiple components, like the Performance Studio, Test Controller, and Analyzer, Performance Injectors, and Web Virtual Users, all which have different hardware requirements.

Stress Stimulus Stress Stimulus is load and stress testing solution that can be used to test websites, web applications, and APIs. Gatling Gatling is another popular open-source load testing tool. LoadRunner LoadRunner, from MicroFocus, is another legacy load testing solution that many developers and teams have heard of, or have even used, as it has been around for a long time.

Locust Locust is an open-source load testing tool based on the Python framework. BlazeMeter BlazeMeter is a paid, SaaS-based functional and performance testing tool, that builds on the open-source features of JMeter, expanding its capabilities, such as scaling up load tests, access to external load injectors, comprehensive and easy to read reports and dashboards, and support for other open-source platforms, like Gatling, Selenium, Locust, Cucumber, and more.

Gatling vs. As we have discussed in this guide, the tool you decide on for your performance tests, whether it is an open-source or paid load testing tool, should support the applications, technologies, and protocols you are testing, is user-friendly, and can provide the necessary reports and data, so you and your teams can properly understand where performance issues are occurring.
