World's best performance benchmarking and load testing tool

Rating: 9 out of 10

Incentivized

May 10, 2022

Use Cases and Deployment Scope

Apache JMeter helps our team in areas like load testing and performance benchmarking of APIs across products and services. Every new feature that gets released is the first load tested using Apahe JMeter, by passing appropriate parameters to check if it can handle the list and stress easily. This helps to assert that the service can easily serve 'x' users in 'y' conditions. With teams focusing more on microservices and agile development, non-functional testing plays a vital role. Apache JMeter is an open-source tool written in pure Java, making it the most preferable option for us to test our services, both API and UI through its user interface as well as Non-GUI mode. This makes the SDET team perform testing and feature releases more confidently with optimum quality.

Pros

Report generation.
Multithreading
Log debugging and sampling.

Cons

Optimize CPU and Memory utilization.
Reporting visuals and metrics.

Likelihood to Recommend

Best suited:
Any new service i.e. monolith or microservice must be load tested to check how it can scale at extreme load, this helps to be prepared early and stay ahead of the competition too.
Not suited:
Limited CPU and Memory resources are available.

Use Cases and Deployment Scope

JMeter is used by both software developers and testers to check that the application functions correctly. It's used in 2 ways: check that the new version of the application functions as expected and also for load testing the application. After the tests are written once by a software developer they can be automated or easily run manually by a non-technical person.

Pros

Load testing. Easy to specify how heavy test is wanted & reports are simple to read.
Doesn't require lots of resources. Tests can be run with normal PC.
Can generate different kind of reports easily.

Cons

Test writing process requires a technical person and needs some learning.
UI elements are rather dated.
Tests recorded with recorder functionality need lots of manual editing to work reliably.

Likelihood to Recommend

JMeter is designed to perform load tests against web applications and suits this purpose well. It is a completely free application and runs on multiple platforms without any hassle. It can also be used to check that the new version of the application functions correctly (regression testing), however, JMeter doesn't actually run the application in the browser but only checks for server responses. The benefit of this is that it requires a lot fewer resources & setup, the drawback is that more complex tests that require lots of UI interaction may not be possible.

Use Cases and Deployment Scope

We used JMeter for performance and load testing of our cloud service to verify that it worked well with many users before launch and also to be able to calculate costs when scaling up the service for more users.

Pros

Easy load testing to verify system with load from many users
Very customizable through your own Java code
Possible to run from a console without any user interface

Cons

Make it easier to record traffic and use that as input during testing

Likelihood to Recommend

It’s great for load testing when you want to apply a load but wants to be sure it’s not restricted by the client machine you run JMeter on. It can be a bit hard to use for people without Java skills.

Use Cases and Deployment Scope

Apache Jmeter scripts are great for load testing. I like the parameterization strategy offered by JMeter because I can better reproduce real-life scenarios by introducing variables and randomizing my tests. Also, JMeter extensions are accessible in the open-source sector to extend current JMeter capabilities. I love this to do my performance testing.

Pros

User interface is not complex. Easy to understand and work flow is very simple.
It comes with many useful testing features.

Cons

It's very difficult to find any cons about this powerful tool. Actually it works perfectly for me.
While installation is very simple, some problems may occur if it is not installed by someone with experience.

Likelihood to Recommend

Apache Jmeter is very useful for parameterizing tests and loading info, which means it has a great performance testing. JMeter will allow you to evaluate if you need to extend outside the existing hardware infrastructure. It can maximize the access to the CSV data by reading it correctly, as the I/O efficiency is overhead. It also offers a very simple user experience, many plug-in modules and a range of graphical maps and descriptive notes to the audience. You could even use the chrome BlazeMeter add-on to capture, retrieve, and create JMSX files in HTML Cookie Manager for an app-based check.

Incentivized

August 24, 2017

Use Cases and Deployment Scope

Jmeter is used within our department for REST API Functional and non-functional test automation. It is fast and reliable and quite extensible, that's why we are using it. A single testing module can be made and very highly paramterized such that it would be executed many times with various parameters combinations. It is also easily integrated with Jenkins as a CI framework.

Pros

REST API Functional and Non-Functional Automated Testing.
Stress and Load Automated Testing.
Highly Parameterized Test Modules.
Excellent Integration with CI Frameworks such as Jenkins.

Cons

Documentation is not user-friendly, you may need quite an extensive amount of time to resolve an issue.
Post processing of page responses is not easy to understand and needs long time to learn, although quite powerful.
Time invested to on-board the application and understand its power, and be able to learn it, can be long.

Likelihood to Recommend

Jmeter is perfectly suited for REST API Automation, specifically Performance Testing, Stress and Load Testing.

Use Cases and Deployment Scope

I am using JMeter for API testing. I designed a data-driven API testing framework with JMeter, which is very helpful for testing APIs as well as setting up some performance tests. I integrate JMeter with Jenkins. It helps our company a lot for performing and managing the API test. And it is easy to set up a performance test system. I have helped my company set up a lab with continuous load testing to measure the performance of our product, as well as setting up an automation performance testing system and shipped it to some of our customers.

Pros

Data-driven api testing framework.
Performance testing.
Easy Integrated with Jenkins.

Cons

When designing API testing with JMeter, the thread hold is very limited.

Likelihood to Recommend

JMeter is well suited for load testing/performance testing/API testing.

February 23, 2016

Use Cases and Deployment Scope

We are doing test cloud-based applications with Apache JMeter. This is used only by my team and not across the organization.

Pros

Extending functional JMeter scripts for reliability testing.
Using the Module Controller to modularize reusable fragments.
JMeter's capabilities as a testing tool for RESTful APIs.

Cons

I think JMeter hangs up on large loads. I have seen JMeter becoming unresponsive in the middle of a test. It is because of garbage collection in JMeter. We use best practices to mute all listeners, use non GUI mode, etc., but even with many best practices JMeter pauses in between load tests.
The reporting feature can be improved to provide better test results.

Likelihood to Recommend

JMeter has great capabilities as a testing tool for RESTful APIs.
