Open Source Performance Testing Tools for Java Application Release provides an integrated visual environment to develop performance tests for Java applications. This software supports developers to create performance test scripts using the scripting language Jython, import functional tests from popular tools like Jtest and Nunit, and execute test scripts within the platform to evaluate the real-world performance of web applications.
We’ve gathered some of the most widely used open source tools in the industry, composed them in a free downloadable toolset, and documented their use so you can easily integrate them into your own performance testing framework.
Siege
Siege is a command line HTTP load testing tool designed to measure codes under stress. It is also used for benchmarking utility. This tool supports basic authentication, cookies, FTP protocols and HTTP and HTTPS. It stimulates user to use the server with a configurable clients who are also stimulated.
Features of Siege
- Simple to use
- Brute-force type testing
- Support multi-protocols
- Stimulates clients
Testing Anywhere
Testing Anywhere is an Automated testing tool that can be employed for testing the performance of any website, web application or any other objects. Many developers and testers make use of this tool to find out the bottlenecks in their web applications and rectify them accordingly.
It is a powerful tool that can test any application automatically. This testing tool comes along with a built-in editor which allows the users to edit the testing criteria according to their needs.
Testing Anywhere tool involves 5 simple steps to create a test. They are object recorder, advanced web recorder, SMART test recorder, Image recognition, and Editor with 385+ comments. This testing software was originally developed by San Jose-based Automation Anywhere Inc. Today, there are more than 25000 users for this product.
System Requirement: This tool is compatible with all versions of Windows OS.
Appvance
The first unified software test automation platform, Appvance UTP eliminates the redundancies created by traditional siloed QA tools that clog DevOps teams.
By unifying tests with its advanced write-once methodology, a functional test can be re-used for performance, load, compatibility, app-penetration, synthetic APM and more, thereby increasing velocity and productivity, reducing costs and finally allowing teams to work and collaborate together.
Appvance UTP offers complete integration with Jenkins, Hudson, Rally, Bamboo & Jira, and also remains compatible with existing tools such as Selenium, JMeter, JUnit, Jython, and others. You can also pass data between applications and script types without any code needed.
Trial account: If you’re interested, you can sign up to “Test drive” the product and request a free demo on the website.
Apica LoadTest
Enterprise-Grade Application and Website Load Testing
Test the scalability of all your applications, identify performance bottlenecks and deliver remarkable customer experiences that transcend the ever-growing expectations of your end-users.
Apica offers flexible self-service and full-service load testing able to test 2M + concurrent users, through a network of 50+ locations around the world. Test on demand or automate testing throughout development lifecycles. Easily integrated into existing Dev stacks using their partnership integrations and their REST API.
Advanced Features include: AJAX/web services, XML/JSON Data Viewer, API data/Execution.
puppeteer-webperf
With most modern applications using javascript heavy front-ends the needs for client-side performance measurements have never been greater.
Don’t ignore front-end performance.
You can use Puppeteer WebPerf to collect web performance stats like a trace for a page load, grab a dev tools trace with screenshots, get runtime performance metrics, and a bunch more.
It currently has 1.4k stars on GitHub.
Flood Element
Want to test real browser load?
Flood created this open-source solution to help specifically with mimicking user behaviors using real browser load testing.
Element is an open-source Playwright that uses a browser-based load testing tool.
Scripts are created using Typescript.
You can use it against your Web app in the same way that your customers do, opening a browser and interacting with page elements.
This approach can help find user-facing performance issues.
It’s written like a functional test script, but with the help of Flood, you can quickly run load testing scripts on as many nodes as you want in the Cloud.
One of the few open-source tools that allow you to create performance testing using real browsers to more closely mimic how real users interact with your application.
It currently has 204 stars on GitHub.
Artillery.io
Artillery.io is an open-source application with an opt-in of premium services to create load tests to simulate load to emulate thousands of users.
It has detailed performance metrics including:
- latency
- requests per second
- concurrency
- capture average response time
- and throughput.
Peak performance testing to handle maximum traffic for your back-end application for stability and reliability.
It has the ability to write custom logic, post, and pretest scenarios using JavaScript, which has a wide variety of NPM modules that you can use.
It supports multiple protocols, including HTTP, Web Socket, Socket.IO, Kinesis, and HLS.
It currently has 4,397 stars on GitHub.
Predator
Open source load testing platform: Predator is the first tool of its kind, an end-to-end solution that manages the entire lifecycle of load testing APIs, from creating and managing existing performance tests to running these tests on a scheduled and on-demand basis, and finally viewing the test results in a highly informative and live, built-in report.
It has a simple, one-click installation, built with support for Kubernetes (helm charts), DC/OS (mesosphere universe), and Docker Engine, making it accessible for anyone and deployable in every machine that supports Docker.
Predator has no limit on the number of virtual users that can run a test, it supports running distributed load out of the box, enabling an unlimited amount of virtual users that can bombard your servers.
Unlike all other testing tools, Predator has a built-in DSL feature, thereby allowing developers to write functional and non-functional performance tests using their own business logic. Bootstrapped with a user-friendly UI alongside a simple REST API, Predator helps developers simplify their performance testing regime.
System Requirements: It works under every OS with Docker.
Conclusion
Performance tests provide a way to measure the application speed under specific load. Jmeter is a very useful tool for setting up such tests. It’s open source and can be easily extended. Freshmeat also has a collection of testing tools with jbehavior test, jwiki benchmark, etc. All of these testing tools can be used in development and testing environments supporting java application servers such as Tomcat, Weblogic, WebSphere, and BEA Weblogic Server.
