Java/Eclipse: How to configure Run Configuration's Classpath for JUnit test?

Question

I have an Eclipse project with the following directory structure:

MyProj/
    src/main/java/
        com.me.myproject.widgets
            Widget.java
    src         


        

Answer 1

If your WidgetTest class is written as a JUnit test, eclipse will try to run it as a Junit test automatically. If it doesn't, you should right click on the class in the package explorer, choose Run As >> Run Configuration >> choose Junit

To run a Junit test:

• in JUnit3, the class should implement TestCase and all the method names should start "test"

• in JUnit4, all the methods should be preceded by a @Test annotation

To place that config file in the classpath: when setting the Run Configuration as above, go to the Arguments tab in the upper right pane and in the VM arguments specify the classpath:

   -cp .:/path/to/the/config/file 

However, if that file is in a package in the source directory, it should automatically be included in the classpath.
