Testing Tools


DDTUnit is a testing framework based on JUnit that focus on a datadriven approach to testing. It separates testcode from testdata by suppliing an easy to learn xml based data description schema. DDTUnit supports complex object description like collections, maps and value objects out of the box.



JTR (Java Test Runner) is a framework meant for fastening the building of both complex and simple test enviroments. It is based on concepts such as Inversion of Control, and is ready for EJB and JMS testing. The JTR 2.0 framework will give you the chance to code only the testing logic. All the boring middleware-related tasks (connecting to ConnectionFactories, opening connections, sharing connections, opening sessions, handleing exceptions, retrieving administered objects) are carried out by the JTR 2.0 runtime on your behalf according to what you have stated in the jtr.xml configuration file. Thanks to IoC (Inversion Of Control), the JTR 2.0 runtime is able to inject all these resources into your IRunner concrete implementations. This entails that you are not required to actively retrieve the resources you need: you declaratively tell the JTR 2.0 framework you are going to need them at runtime, and Inversion Of Control will do the work. The thing same happens with EJBs: all the low-level details are always handled by the JTR framework to let you work only on the pure logic of your tests.



Mock is a widely used technology in unit test domain. It shields exteral and unnecessary factors and helps developers focus on the specific function to be tested. EasyMock is a well known mock tool which can create mock object for given interface at runtime. The mock object's behavior can be fine defined prior the test code in the test case. EasyMock is based on java.lang.reflect.Proxy, which can create dynamic proxy class/object according to the given interfaces. It has the inherent limitation from the Proxy. It can create mock object for given interface only. Mocquer is a similar mock tool as EasyMock. With the help of Dunamis Project, it extends the function of EasyMock to support mock object creation for both class and interface.



p-unit is a framework for performance benchmark and unit test. It records memory consumption and execution time, and generates result in the form of plain text, image and pdf file. p-unit allows users to plugin their own result report. As a tool for unit-test, p-unit supports to run the same tests with a single thread or multi-threads.



T2 is a random testing tool. As one, it is fully automatic, but one must keep in mind that the code coverage of random testing is in general very limited. It should be used as a complement to other testing methods. T2 checks for internal errors, run time exceptions, method specifications, and class invariant. T2 does not check individual methods in isolation; instead T2 generates random executions where methods may interfere with each other, and thus it may discover more subtle errors. Violating executions can be saved for re-test (regression). No special specification language is needed. Specifications are written in plain Java. The current state is prototype.



Jumble is a Java mutation testing tool that works in conjunction with JUnit. The purpose of mutation testing is to provide a measure of the effectiveness of test cases. A single mutation is performed on the code to be tested, the corresponding test cases are then executed. If the modified code fails the tests, then this increases confidence in the tests. Conversely, if the modified code passes the tests this indicates a testing deficiency.



Jameleon is an acceptance-level automated testing tool that separates applications into features and allows those features to be tied together independently, creating test-cases. These test-cases can then be data-driven and executed against different environments. Even though it would be possible to write unit tests using Jameleon, Jameleon was designed with integration and acceptance-level testing in mind.



benerator is a framework for creating realistic and valid high-volume test data, used for testing (unit/integration/load) and showcase setup. Metadata constraints are imported from systems and/or configuration files. Data can imported from and exported to files and systems, anonymized or generated from scratch. Domain packages provide reusable generators for creating domain-specific data as names and addresses internationalizable in language and region. benerator is strongly customizable with plugins and configuration options.
