Unit testing is a basic software testing activity that should be performed by every software developer. This handout produced by the Computer Science department of Stanford University introduces the ideas of unit testing and provides some examples on how to do it with JUnit in Eclipse.
Finding common naming conventions for software development items (variables, classes, etc.) is a major factor to help people collaborate in software development projects. Finding good names is also good if you work on your own and have to revisit your code some months after you wrote it. In this blog post Frank Appel discusses his experience with naming JUnit tests.
Unit testing seems to be the most natural way for programmers to test their own code. In this small blog post, Henrik Warne shares some of the issues that people have when they switch from manual testing to a unit testing framework like JUnit.
Easy Coverage is an open source framework that can dynamically generate Java unit tests to perform basic verifications. Easy Coverage is extensible and highly configurable. It can work as a standalone product or it can be used with JUnit. In his blog post, Romain Delamare explains how to dynamically generate Java unit tests with Easy Coverage.
The open source JUnit unit testing tool has been a blessing for Java developers. However, many programmers think that it is enough to learn the JUnit API and write a few tests in order to have a well-tested application. This idea is more dangerous than not doing unit tests because it leads to a wrong sense of code quality. Learning JUnit is the easiest part of unit testing your Java code, but writing good tests is the hard part.
This short video provides an introduction to automated software testing in Java with Selenium and Junit.
This is a brief video on how to use the JUnit open source unit testing framework for Java. By using JUnit, you can assert that methods in your Java code work as designed, without the need to set up the complete application.
