EasyMock provides Mock Objects for interfaces in JUnit tests by generating them on the fly using Java's proxy mechanism. Due to EasyMock's unique style of recording expectations, most refactorings will not affect the Mock Objects. So EasyMock is a perfect
Test driven development (TDD) is emerging as one of the most successful developer productivity enhancing techniques to be recently discovered. The three-step: write test, write code, refactor – is a dance many of us are enjoying. This site is dedicated to promoting techniques, tools, and general good will in the test-driven community.
The simple, flexible Marathon Java testing tool reached version 1.0. With this Marathon garnered the ability to record almost all actions on standard Java/Swing controls including drag and drop. Marathon records all actions on unrecognized user interface elements, so you can use Marathon for even automating actions on non-standard components. Use custom component resolvers to further extend Marathon to record semantic actions on your custom components. Benefit from the improvements to Marathon, like dock-able windows, cut&paste operations in the editors and of course, tabbed editing facilities. Download Marathon now and explore the possibilities of test automation.
iValidator is a framework for XML-based test automation of complex test scenarios. iValidator is completely written in Java. The framework is available under an open source licence.
For those of you who've got into it you'll know that test driven development is great. It gives you the confidence to change code safe in the knowledge that if something breaks you'll know about it. Except for those bits you don't know how to test. Until now XML has been one of them. Oh sure you can use "<stuff></stuff>".equals("<stuff></stuff>"); but is that really gonna work when some joker decides to output a <stuff/>? -- damned right it's not ;-)
Feedback is vital for the practice of Continuous Integration (CI) -- in fact, it's the life blood of a CI system. Rapid feedback enables speedy responses to build events that require attention. Without feedback mediums like e-mail or RSS, builds in a broken state have the tendency to stay broken, which defeats the purpose of CI in the first place! In this installment of Automation for the people, automation expert Paul Duvall examines various feedback mechanisms that you can incorporate into CI systems.
Phantastic!
"EclEmma is a free Java code coverage tool for Eclipse, available under the Eclipse Public License. Internally it is based on the great EMMA Java code coverage tool, trying to adopt EMMA's philosophy for the Eclipse workbench:
* Fast develop/test cycle: Launches from within the workbench like JUnit test runs can directly be analyzed for code coverage.
* Rich coverage analysis: Coverage results are immediately summarized and highlighted in the Java source code editors.
* Non-invasive: EclEmma does not require modifying your projects or performing any other setup.
The Eclipse integration has its focus on supporting the individual developer in an highly interactive way.
The update site for EclEmma is http://update.eclemma.org/."
Canoo WebTest is a free open source tool for automated testing of web applications.
It calls web pages and verifies results, giving comprehensive reports on success and failure. The White Paper provides an overview of the features and the design rationale. Detailed information is provided in the Manual Overview as well as the Install and Troubleshooting guides.
In what I hope will be the first of several articles about Guice, a new lightweight dependency injection container from Bob Lee and Kevin Bourillion from Google, this article examines the simplest and most obvious use case for the Guice container, for mocking or faking objects in unit tests. In future articles I will examine other, more ambitious areas where it can be used, including dependency elimination in large code bases.
RMock 2.0.0 is a Java mock object framework to use with jUnit. RMock has support for a setup-modify-run-verify workflow when writing jUnit tests. It integrates better with IDE refactoring support and allows designing classes and interfaces in a true test-first fashion.
AtUnit minimizes boilerplate code in unit tests and guides test development by enforcing good practices.
* mark exactly one field with @Unit to indicate the object under test.
* mark fields with @Mock or @Stub to obtain mock objects
* inject your tests, and your test subjects, using your favorite IoC container
Mock Objects Integration
AtUnit integrates with JMock or EasyMock to provide mock objects:
* obtain a JMock context simply by declaring a field
* annotate fields with @Mock to obtain JMock or EasyMock mock objects
* annotate fields with @Stub to obtain a JMock or EasyMock stub object
... or you can use your own mock objects plug-in with two easy steps:
* implement the MockFramework interface
* annotate your tests with @MockFrameworkClass(MyMockFramework.class)
Container Integration
AtUnit integrates with Guice or Spring to take all of the work out of dependency-injected tests.
With Guice:
* never see the Injector, never write bootstrapping boilerplate!
* @Inject test class fields without even defining a Module
* declaratively obtain mock objects with @Inject @Mock
* if you need more binding flexibility, simply have your test class implement Module
With Spring:
* annotate fields with @Bean to get them from the Spring context
* fields annotated with @Bean which do not appear in your Spring context are added to it automatically! (This includes @Mock and @Stub fields.)
* AtUnit looks for a Spring XML file with the same name as your test, or you can specify the location yourself with @Context("filename")
* Most of the time, you don't even need a Spring XML file!
You can easily plug in other containers in two steps:
* implement the Container interface
* annotate your tests with @ContainerClass(MyContainer.class)
ClassMock is a framework that helps the creation of unit tests for components that use reflection or annotations. In this kind of classes, the behavior is dependent of the class structure. This way, each test case usually works with a different class created specifically for the test. With ClassMock is possible to define and generate classes in runtime, allowing a better test readability and logic sharing between tests.
Ripplet is a powerful,high available,flexible,collaborative load/stress test tool. It aims at providing an environment where users are able to do the tasks as follows :
* illustrate test design and outline load description clearly
* control realistic performance load efficiently, both on logic and data flow
* diagnose performance spikes and bottlenecks easily
* evaluate system capacity quickly and correctly
* share achievements for developers or customers, not only reports but test plan for product enviroment stage evaluation
Use it, extend it, just making your load test fruitful, your production stable. Hopefully, it's pretty much everything you seek in load test and it's beyond your expectation.
There are many Continuous Integration systems available. This page is an attempt to keep an unbiased comparison of as many as possible of them. The goals are:
* Make it easier to choose an appropriate CI tool for your project.
* "Healthy competition aid" for the people involved in the development of these various CI systems.
Nice article on IBM deveWorks: Ready to step up to the plate and hit a home run with your developer testing activities? In this installment of Automation for the people, development automation expert Paul Duvall covers some of the various types of automated developer tests you can run with every source code change. Paul provides examples of Selenium, DbUnit, and JUnitPerf tests that can help you discover application problems early -- that is, if they're run often.
Unitils is an open source library aimed at making unit testing easy and maintainable. Unitils builds further on existing libraries like DBUnit and EasyMock and integrates with JUnit and TestNG.
Unitils provides general asserion utilities, support for database testing, support for testing with mock objects and offers integration with Spring and Hibernate. It has been designed to offer these services to unit tests in a very configurable and loosely coupled way. As a result, services can be added and extended very easily.
Currently Unitils offers following features:
* General testing utilities
o Equality assertion through reflection, with different options like ignoring Java default/null values and ignoring order of collections
* Database testing utilities
o Automatic maintenance and constraints disabling of unit test databases
+ Support for Oracle, Hsqldb, MySql, DB2, Postgresql and Derby
o Simplify unit test database connection setup
o Simplify insertion of test data with DBUnit
o Simplify Hibernate session management for unit testing
o Automatically test the mapping of Hibernate mapped objects with the database
o Manage transactions during unit testing
* Mock object utilities
o Simplify EasyMock mock object creation
o Simplify mock object injection
o EasyMock argument matching using reflection equality
* Spring integration
o ApplicationContext configuration and easy injection of spring managed beans into a unit test
o Support for using a Spring-configured Hibernate SessionFactory in unit tests.
The project started begin 2006 from an Ordina J-Technologies discussion group on unit testing. The result was a list of guidelines and Unitils emerged in an attempt to write code to support these guidelines.

DJProf is an experimental Java profiling tool which employs AspectJ to insert the necessary instrumentation for profiling rather than, for example, the Java Machine Profiler Interface (JVMPI). DJProf can be used to profile Java programs without modification (i.e. there is no need to recompile them for profiling) and does not require the user to have any knowledge of AspectJ. The Load-Time Weaving capability of AspectJ is utilised to make this possible. The tool (including its source code) is release under a very straightforward (and unrestrictive) license for the benefit of all.
Profiler4j is an open-source CPU profiler for Java. To get started, just follow the tutorial or see some screenshots.
Notice that this project is in beta stage and still have some bugs. However, as far as I know, it is fairly stable with typical applications such as Tomcat and JBoss. A final hint: if you develop in JDK1.4 or 1.3, please see this FAQ.
