Open Source Java Performance Testing Software

The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by a dedicated international team of volunteers. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. It's also a great tool for experienced pentesters to use for manual security testing. ZAP is an easy to use integrated penetration testing tool for finding vulnerabilities in web applications. It is designed to be used by people with a wide range of security experience and as such is ideal for developers and functional testers who are new to penetration testing. ZAP provides automated scanners as well as a set of tools that allow you to find security vulnerabilities manually. It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application.

Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. There’s also a cross-platform stand-alone executable for teams not comfortable with Java. You don’t have to compile code. Just write tests in a simple, readable syntax, carefully designed for HTTP, JSON, GraphQL and XML. And you can mix API and UI test-automation within the same test script. A Java API also exists for those who prefer to programmatically integrate Karate’s rich automation and data-assertion capabilities. It is worth pointing out that JSON is a ‘first class citizen’ of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes.

Marathon provides an integrated environment for test script creation and execution. Supported FW: Web, Java Swing/ Java FX. Currently, Marathon supports JRuby script models for recording the test scripts.Marathon test runner generates Allure test reports.Marathon allows for grouping of test cases.It also has an option of inserting modules while recording(in MarathonITE while recording). It allows tester to inset checklist while recording and also takes screen capture and annotate it in playing the test cases. Extraction of code into modules and inserting it is very easy using marathon.It has different themes of UI which attracts tester to do work on it. Object mapping is quite simple and configuring is very easy for tester to understand and do the work. Debugging of test scripts is also easy and has script console which takes selenium commands. Slow play of test cases is also available.It allows to create multiple fixtures for different types of tests.

CAT is a distributed application performance monitoring and alerting system that specializes in tracking request flows, exceptions, and metrics across microservice ecosystems. It offers real-time dashboards showing throughput, response times, error rates, and service dependency graphs to help operations and development collaborate on reliability issues. In addition to metrics, it enables tracing—propagating context across RPC boundaries so problems like latency spikes or failed calls can be traced end-to-end. Alert rules and anomaly detection can be defined to notify teams proactively. The system supports multiple data backends and ingestion pipelines to collect data from JVM, C/C++, Python, and other ecosystems. With the collected data, Cat supports analysis of hotspots, trending anomalies, and capacity planning to drive continuous reliability improvements.

BenchLab is a Web Application benchmarking framework using real web browsers.

An open-source desktop application for load/performance testing a web site. It has a very simple UI to configure the load test. The future plan includes transaction support, record, playback and support for load injector agents.

Beet adds user behavior and performance tracking to a Spring-based Java app. HTTP requests, method calls, and SQL statements are tracked and associated to user and session. includes XML, binary XML, and JDBC loggers. See http://beet.sourceforge.net.

Boest is an application for stress testing an SAP BusinessObjects Enterprise deployment. It launches a series of tests in parallel from which we can measure performance of the BOE system

Java app. to utilise (waste) as much CPU as it can. The application allows the user to create multiple Java threads, each performing a CPU-intensive task tasks with a selectable memory footprint. The options let you 'thrash' the aspect you want.

Conductor is a Java based, multi-user platform for product agnostic testing. It runs under a web server, contains a UI for test configuration, and contains an optional thin test client.

In order to assure software performance, software needs to be tested accordingly as early as possible - only weaknesses diagnosed early can be assessed quickly and cheaply. ContiPerf enables performance testing already in early development phases and in an easy-to-learn manner: A developer writes a performance test in form of a JUnit 4 test case and adds performance test execution settings as well as performance requirements in form of Java annotations. When JUnit is invoked by an IDE, build script or build server, ContiPerf activates, performs the tests and creates an HTML report. The report provides a detailed overview of execution, requirements and measurements, even providing a latency distribution chart. A large feature set for execution settings and performance requirements is available, e.g. Ramp up, warm up, individual pause timing, concurrent exection of test groups and more.

Quite useful library for code diagnosis. As for now it can measure time of working for simple blocks of code, but features like loop or counters are developed.

Regulador de Temperatura de El Suri (GNU/GPL) Sólo para Linux, testeado en OpenSuSE 11.3 x64 con procesadores Turion X2 El Suri Temperature Control (GNU/GPL) Just for Linux, tested on OpenSuSE 11.3 x64 with Turion X2 processors

Real-time production information is needed to optimize manufacturing activities in a factory, but acquiring this information from isolated proprietary equipment is a manual process that takes time and introduces errors. Connecting equipment to the factory network can make accurate production information immediately available, but widespread interconnection of equipment has been inhibited by the lack of common information models and methods to measure performance and conformance. This project will develop and deploy a measurement science-based performance and conformance testing framework to enable real-time factory floor monitoring and optimization of manufacturing applications.

This is a Windows Form application, developed in C#. The purpose of this application is to edit and customize script taken from The Grinder recorder to suit ones needs. The recording, editing and testing of scripts can be done mostly within application. This application also supports managing multiple script executions at once. To learn more, please, take a look at users manual!
