JUnit Factory is a free test-generation service from Agitar Software.
Upload a Java project and JUnit Factory will send back JUnit tests that
characterize your code's behavior.
You can download our plug-in for Eclipse or try the online demo at
http://www.junitfactory.com.
JUnit Factory includes a code coverage plug-in for Eclipse.
Lowering the step toward JUnit by offering a convenient way to create, organize and maintain JUnit tests. Generates TestSuites, TestCase skeletons and default tests from Java sources. Incremental behaviour keeps modified code when regenerating. Assists with refactorings (no tests get lost when renaming, moving, etc.). Because it is a Doclet it works very well with ANT.
Cricket Cage uses AspectJ to insert code into your classes to generate the code for the test case. The aspects defined capture every call executed from outside a set of classes to every call on classes within that set. Cricket Cage makes creating the test state gets very easy.
JavaBean Tester is a tool to automate the testing of JavaBeans. Eliminate the error-prone tedium of writing tests for JavaBean accessor/mutator pairs by letting these classes do it for you. They are simple to use in any Java environment.
Lets assume you started developing your application some weeks ago or some months ago or even some years ago. I am sure that testing your code was one of major problems. You thought about automating such process. And than you heard about Unit Testing. So you would like to start use it. However how to introduce Unit Testing for large number of source files. There is too much of stupid code to write in all places again. That is where this package comes in.
