![]() We really do mean "small", but there's enough for you to understand the BlueJ basics. If you've some development experience and want to jump right in, then there are some small example projects in the BlueJ folder (C:\Program Files (x86)\BlueJ\examples by default). If you are totally new to Java then you should probably begin with the BlueJ readme file (see C:\Program Files (x86)\BlueJ\README.TXT by default), which points you to a useful tutorial and offers other advice on getting started.

The BlueJ download we're linking here contains its own code and Oracle's Java Development Kit, which is everything you need to get started. It's designed to help novices learn Java and object-oriented programming, although the more experienced can also use it to develop simple applications.

As they become familiar with JUnit's terminology, they can write their own test cases in the source code editor window, much like they write plain Java code. The recording of the test methods allows the beginning student to capture testing expressions without having to know the syntax of JUnit. In BlueJ, you first create a test class, record your test cases (methods), and then execute either all of your test cases or individual test methods. If you have a recent version of BlueJ, you already have all you need to use JUnit. The current version of BlueJ (version 3.0.7), avialable at, includes support for testing directly integrated in the IDE. The JUnit home on SourceForge ( ) has several good sources for learning JUnit, including release notes, a Cookbook, Javadoc, and frequently asked questions.Īt the time of this writing, there are three main unit test frameworks for Java. Instructions for git are available on this page. You can download it in zip or tar format or even just clone the project using git. You can download JUnit from its home on the web ( ). Nevertheless, it is good to familiarize yourself with the online repository where JUnit lives and with the options for downloading JUnit directly. Since most IDEs include support for JUnit, the jar files for JUnit are already included in your setup. For more professional treatment of testing,Ĭheck the Reference section to see other material. Testing support that you can use in lectures, assignments or that your students To show you how to use testing in the classroom, and as such, we will focus on On how to run tests from the command line (shell), just in case you prefer the However, provides very different support for creating tests,Įxecuting tests, and managing your testing process. ![]() Versions of these systems come preconfigured with JUnit.
