Netbeans working directory10/30/2023 With the source code written, the JUnit-based unit tests written, and the NetBeans Java Application project set up as shown above, it is almost trivial to run the unit tests.

The source code for the classes (source and test) displayed above is shown next.Īdder.java (Class to be tested) package dustin The image also shows that Java SE 6 and JUnit 4.5 are being used. The image above shows that this NetBeans project (which was created previously as a Java Application project using the NetBeans New Project creation wizard) is called "IndividualTesting." More importantly, this image shows the two main source classes (Adder and Multiplier in the "Source Packages" area) and their respective test classes (AdderTest and MultiplierTest in the "Test Packages" area). The directory structure for this project with the test classes and the classes to be tested is shown next in this screen snapshot of the NetBeans "Projects" window. For the IDE and command-line examples, I will be using two classes two be tested and two test classes that will test those classes. When using the NetBeans New Project wizard to create a Java Application project, one gets an Ant-compliant build.xml file as the main project build file, but most of the real work is delegated to the build-impl.xml file that is generated and placed in the nbproject subdirectory of the main project working directory.īefore demonstrating how to run an individual Test Class from the command-line line, I'll first look at how to do it through the IDE. This blog posting covers the minor things one needs to know to run individual JUnit-based unit tests from the command-line using an Ant build.xml file generated by NetBeans 6.1 or NetBeans 6.5 for a standard Java Application project. NetBeans supports executing a single unit test class from the command-line, but I have found that you need to be aware of a few tricks to do this. This is easy to do in the IDE itself, but it is something I also want to do from the command-line. It can be very useful to execute a single JUnit-based unit test class rather than executing the entire unit test suite. In particular, there are times when I want to do things from the command-line without the need to open up the IDE. However, I like to be able to do anything I might do often outside of the IDE as well as from within the IDE. The NetBeans IDE provides JUnit integration that can be very handy when writing and running JUnit-based unit tests.
