Testing Tools


TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use, such as: - JSR 175 Annotations (JDK 1.4 is also supported with JavaDoc annotations). - Flexible test configuration. - Default JDK functions for runtime and logging (no dependencies). - Powerful execution model (no more TestSuite). - Supports dependent methods.



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.



Given the interface or class, it generates source of Mock object for it.



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.



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.



Mockrunner is a lightweight framework for unit testing applications in the J2EE environment. It supports Struts actions and forms, servlets, filters and tag classes. Furthermore it includes a JDBC and a JMS test framework. The JDBC test framework can be used standalone or in conjunction with MockEJB to test EJB based applications.



StrutsTestCase is an extension of the JUnit TestCase class that allows testing of individual Action objects with or without a running servlet engine. This framework provides both mock servlet objects as well as Cactus support to simulate the environment.



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.
