List of Best Java Unit Testing Frameworks and Tools

If you have not done unit testing, you should not consider your code production-ready. Unit testing is the developer’s responsibility to complete before they ship the code for other white-box testing. There are many frameworks and tools available in the market. I have listed some of the Java unit testing frameworks and tools. Please feel free to comment on which one you are using and your opinion about that.

JUnit – Java Unit Testing Framework

junit testing framework

JUnit is one of the famous Java testing framework written by Erich Gamma and Kent Beck. It is a regression testing framework. Junit helps the developer write test cases, so-called white box testing because the programmer knows the code and can quickly write test cases using jUnit. Using class inheritance, developers can easily automate the testing.

Cactus – Java Unit Testing

cactus unit testing framework

Cactus is a simple test framework based on the JUnit framework for unit testing with server-side Java code. The Cactus framework’s primary goal is to use unit testing server-side Java Servlet objects such as HttpServletRequest, HttpServletResponse, HttpSession.

StrutsTestCase – JUnit Extension

struts junit extension

StrutsTestCase is the extension of the Junit TestCase class that provides code based on the Struts framework tests. StrutsTestCase provides both Mock objects and Cactus methods used to run the Struts ActionServlet. You can run the servlet engine to test. StrutsTestCase uses the ActionServlet controller to test your code.

You can test the Action object’s implementation, test mappings, and forwards declarations. StrutsTestCase does not start the servlet container to test your Struts application, but it mocks the object, different from the EasyMock. EasyMock provides the API for creating Mock objects, while StrutsTest is dedicated to testing the Mock Object.

JFCUnit – Java Unit Testing

  3. Acolyte : http://acolyte.eu.org/ : Allow to manage JDBC connection to mimic any DB to provide persistence cases required (which query/update are supported, with which resultset/updatecount in each case), isolated and without required cleanup for easy unit test about JDBC/persistence code.

    Usable either in vanilla Java (pure JDBC code, EJB, JPA, with JNDI, …), or with Scala (Anorm, Slick, …).
